[PMID: 38170152 PMCID: PMC10761219 DOI: 10.1155/2023/5967638] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 11/20/2023] [Accepted: 12/19/2023] [Indexed: 01/05/2024]
Abstract
A molecule's antibacterial and antiviral action is exclusively linked to substances that selectively eradicate bacteria and viruses or inhibit their growth without significantly damaging adjacent tissues. The purpose of this research is to evaluate quantitative and qualitative phytochemical analysis and the antibacterial effects of Manilkara zapota fruit extract on some Gram-positive (Staphylococcus aureus, Enterococcus faecalis, Micrococcus luteus, Bacillus cereus, and Listeria monocytogenes) and Gram-negative (Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae) bacteria in laboratory conditions. Qualitative chemical screening was used to identify different classes of active chemical compounds, and quantitative analysis of the chemical composition of the plant was used to measure the contents of flavonoid, total phenol, anthocyanin, and antioxidant activity. Antibacterial effects of Manilkara zapota ethanol extract were determined by disk diffusion methods, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC). Qualitative chemical screening revealed the presence of flavonoids, tannins, quinones, terpenoids, and glycosides while the presence of saponins was not observed. The bacterial inhibition zones against Listeria monocytogenes, Enterococcus faecalis, Pseudomonas aeruginosa, Staphylococcus aureus, Micrococcus luteus, Escherichia coli, Klebsiella pneumoniae, and Bacillus cereus are 15.44 ± 0.33, 12.23 ± 0.11, 8.85 ± 0.2, 14.22 ± 0.33, 15 ± 0.44, 9.33 ± 0.13, 10.33 ± 0.36 and 14.55 ± 0.45 mm, respectively. MIC and MBC of the extract in Gram-positive bacteria were 25 and 50, and in Gram-negative bacteria were 50 and 100 mg/ml, respectively. The findings imply that Manilkara zapota extract includes a good amount of plant compounds and can be a significant source for a variety of uses, including antibacterial.

Antidiabetic, antihyperlipidemic and protective effects of Gladiolus psittacinus on hyperglycemia-mediated oxidative stress in streptozotocin-induced diabetic rats. JOURNAL OF COMPLEMENTARY & INTEGRATIVE MEDICINE 2023; 20:353-364. [PMID: 36883746 DOI: 10.1515/jcim-2023-0018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Accepted: 02/16/2023] [Indexed: 06/16/2023]
Abstract
OBJECTIVES Gladiolus psittacinus (GP) is an important medicinal plant in folk medicine where its corm is used for treatment of diabetes mellitus. Despite this, there is paucity of scientific information to justify its use as antidiabetic drug. Hence, this study was designed to explore antidiabetic, antihyperlipidemic and effects of aqueous extract of Gladiolus psittacinus (AGP) on hyperglycemia-associated oxidative stress in pancreas, kidney and liver of diabetic rats. METHODS Diabetes mellitus (DM) was induced in rats using streptozotocin 50 mg/kg (i.p.). Normal and diabetic rats were treated orally with AGP once a day for 14 days. Antidiabetic effects were evaluated on body weight, fasting blood glucose concentration (FBGC), lipid profiles and serum chemistry. Also, protective effects of AGP were also determined on markers of oxidative stress, antioxidant enzymes and histopathology of pancreas, kidney and liver of diabetic rats. RESULTS Treatment with AGP emanated to significant decrease of FBGC (552.67-157.33 mg/dL), increase in body weight (100.01-133.76 g) and positive modulation of lipid parameters in diabetic rats. The alteration in the contents of markers of liver and kidney function were significantly modulated in the diabetic rats upon treatment. Also, oxidative damage and antioxidant depletions in pancreas, kidney and liver were significantly mitigated in treated diabetic rats. Structural aberrations in the histopathology slides of pancreas, kidney and liver were improved upon treatment. CONCLUSIONS It can be concluded that AGP could be used in the treatment of diabetes mellitus and its related ailments, thereby justifying its usage in traditional medicine.

Abstract
The antihyperglycemic activity of ethanolic extract from Annona cherimola Miller (EEAch) and its products were evaluated using in vivo and in silico assays. An α-glucosidase inhibition was evaluated with oral sucrose tolerance tests (OSTT) and molecular docking studies using acarbose as the control. SGLT1 inhibition was evaluated with an oral glucose tolerance test (OGTT) and molecular docking studies using canagliflozin as the control. Among all products tested, EEAc, the aqueous residual fraction (AcRFr), rutin, and myricetin reduced the hyperglycemia in DM2 mice. During the carbohydrate tolerance tests, all the treatments reduced the postprandial peak such as the control drugs. In the molecular docking studies, rutin showed more affinity in inhibiting α-glucosidase enzymes and myricetin in inhibiting the SGLT1 cotransporter, showing ∆G values of -6.03 and -3.32 kcal/mol-1, respectively, in α-glucosidase enzymes. In the case of the SGLT1 cotransporter, molecular docking showed ∆G values of 22.82 and -7.89 in rutin and myricetin, respectively. This research sorts in vivo and in silico pharmacological studies regarding the use of A. cherimola leaves as a source for the development of new potential antidiabetic agents for T2D control, such as flavonoids rutin and myricetin.

Abstract
The reuse of food by-products is crucial for the well-being of the planet. Considering the high content of nutrients and other bioactive compounds in many of them, investigating their suitability for use as human food ingredients is an interesting challenge. In this study, in addition to the proximate composition, phenol content and antioxidant activity (AOA = 3.2 mmol Trolox equivalent (TE)/100 g, db) of orange juice powder by-product (CoP), different in vitro properties related to carbohydrate metabolism have been characterised. Specifically, the glycaemic index (GI), the glycaemic load (GL), the glucose dialysis retardation index (GDRI = 13.6%), the glucose adsorption capacity (GAC = 22.5 mM) and the inhibition capacity of α-amylase (α-A = 46.9%) and α-glucosidase (α-G = 93.3%) of powdered orange juice waste have been determined and related to fibre and phenolics composition. Taking advantage of the high fibre content of the by-product (36.67%), its GL was calculated for a CoP dose that allows labelling the food to which it is added as a source of fibre. The low GI value (24.4%) and the low GL (0.918 g available carbohydrates per serving) allowed us to conclude that the product studied could be an interesting opportunity for the food industry to offer it as a healthy food ingredient to be included in the diet, especially for those suffering from type 2 diabetes mellitus. Of the total phenolic compounds (TP = 509 mg equivalent of gallic acid (GAE)/100 g, db), 68% were found in free fraction (FP), and their contribution to the total AOA was 40.6%, while this was 54.9% for the 32% of phenols bound to plant tissues (BP).

Abstract
This study was designed to screen novel thiourea derivatives against different enzymes, such as α-amylase, α-glucosidase, protein tyrosine phosphatase 1 B, and advanced glycated end product (AGEs). A cytotoxicity analysis was performed using rat L6 myotubes and molecular docking analysis was performed to map the binding interactions between the active compounds and α-amylase and α-glucosidase. The data revealed the potency of five compounds, including E (1-(2,4-difluorophenyl)-3-(3,4-dimethyl phenyl) thiourea), AG (1-(2-methoxy-5-(trifluoromethyl) phenyl)-3-(3-methoxy phenyl) thiourea), AF (1-(2,4-dichlorophenyl)-3-(4-ethylphenyl) thiourea), AD (1-(2,4-dichlorophenyl)-3-(4-ethylphenyl) thiourea), and AH (1-(2,4-difluorophenyl)-3-(2-iodophenyl) thiourea), showed activity against α-amylase. The corresponding percentage inhibitions were found to be 85 ± 1.9, 82 ± 0.7, 75 ± 1.2, 72 ± 0.4, and 65 ± 1.1%, respectively. These compounds were then screened using in vitro assays. Among them, AH showed the highest activity against α-glucosidase, AGEs, and PTP1B, with percentage inhibitions of 86 ± 0.4% (IC50 = 47.9 μM), 85 ± 0.7% (IC50 = 49.51 μM), and 85 ± 0.5% (IC50 = 79.74 μM), respectively. Compound AH showed an increased glucose uptake at a concentration of 100 μM. Finally, an in vivo study was conducted using a streptozotocin-induced diabetic mouse model and PTP1B expression was assessed using real-time PCR. Additionally, we examined the hypoglycemic effect of compound AH in diabetic rats compared to the standard drug glibenclamide.

Abstract
Background Bioaccumulation of aluminum in the brain is associated with adverse neuroinflammatory and neurodegenerative changes, such as those seen in Alzheimer's disease (AD). Objective This study aimed to assess the impact of the administration of Lepidium sativum (LS) extract on behavioral, biochemical, and cerebral histopathological changes in rats with AlCl3-induced AD and explore the mechanism behind this effect. Materials and Methods This study was conducted on 40 male albino rats divided into four groups (n=10): LS (control, 20 mg/kg body weight for 8 weeks), AD (AlCl3, 10 mg/kg body weight), and an LS-treated AD group. Behavioral assessment included radial armed maze and active avoidance training tests. Proinflammatory cytokines, oxidant/antioxidant markers, Aβ, AchE, tau protein, TGFβ1, homocysteine, folic acid, and vitamin B12 were biochemically assessed in the serum. The cerebral cortex was histopathologically examined. Results AlCl3 administration significantly impaired rats' memory, indicating AD-like behavioral changes, significantly increased (P<0.001) oxidative stress markers, enhanced proinflammatory cytokines, and significantly increased AChE (P<0.001) adding to cytotoxic effects and neuronal loss in the cerebral cortex. LS administration significantly improved the antioxidant parameters, reduced proinflammatory cytokines, and alleviated AD-associated histopathological changes. Conclusion LS ameliorated AlCl3-induced changes through its antioxidant, anti-inflammatory, and antiapoptotic effects, suggesting that it has a neuroprotective effect.

Abstract
Diabetes is a metabolic pathology with chronic high blood glucose levels that occurs when the pancreas does not produce enough insulin or the body does not properly use the insulin it produces. Diabetes management is a puzzle and focuses on a healthy lifestyle, physical exercise, and medication. Thus far, the condition remains incurable; management just helps to control it. Its medical treatment is expensive and is to be followed for the long term, which is why people, especially from low-income countries, resort to herbal medicines. However, many active compounds isolated from plants (phytocompounds) are poorly bioavailable due to their low solubility, low permeability, or rapid elimination. To overcome these impediments and to alleviate the cost burden on disadvantaged populations, plant nanomedicines are being studied. Nanoparticulate formulations containing antidiabetic plant extracts or phytocompounds have shown promising results. We herein aimed to provide an overview of the use of lipid- and inorganic-based nanoparticulate delivery systems with plant extracts or phytocompounds for the treatment of diabetes while highlighting their advantages and limitations for clinical application. The findings from the reviewed works showed that these nanoparticulate formulations resulted in high antidiabetic activity at low doses compared to the corresponding plant extracts or phytocompounds alone. Moreover, it was shown that nanoparticulate systems address the poor bioavailability of herbal medicines, but the lack of enough preclinical and clinical pharmacokinetic and/or pharmacodynamic trials still delays their use in diabetic patients.

Abstract
Fruit extracts of Momordica charantia L. (Cucurbitaceae) and Abelmoschus esculentus (L.) Moench (Malvaceae) have shown promising antidiabetic activities in clinical trials. However, they remain underutilized due to insufficient standardization and lack of formulation containing their mixture. This study’s overall purpose was to develop and optimize a capsule dosage form containing dried fruit extracts of M. charantia and A. esculentus. The design of the experiment involved two steps; first, response surface methodology (RSM) with a five-level two-factor central composite rotatable design (CCRD) was employed to determine the optimal dose of a mixture of extracts for adequate glycemic control. The extract of M. charantia and A. esculentus were the independent variables while fasting plasma glucose (FPG) was the dependent factor. In the second step, a D-optimal mixture design was applied to study the interaction effect of the optimal dose and selected excipients on granules flowability and capsules’ disintegration time. Moreover, a second-order quadratic model determined the interrelationship of excipients and the desired capsules’ quality attributes. The validity of the predicted models was confirmed. The findings indicated that a combined dose of 175 A. esculentus and 281 M. charantia (mg/kg) significantly reduced the FPG level compared to vehicle at day 14 (mean difference -2.7 ± 0.21, p < 0.001). This dose was used to make a 600 mg capsule (DM083) with 76% drug loading. The DM083 had 40.4 ± 0.62 mg GAE/gDW total polyphenols, 12 peaks HPLC fingerprint, and 26.6 ± 4.75 min average disintegration time. Together, these findings showed that a mixture of M. charantia and A. esculentus fruit extracts could be formulated in a stable capsule dosage form with acceptable quality standards. Further biological studies such as toxicity assays and long-term efficacy studies of the developed capsules could be carried out before large-scale commercial production.

Abstract
Diabetes has become common lifestyle disorder associated with obesity and cardiovascular diseases. Environmental factors like physical inactivity, polluted surroundings and unhealthy dieting also plays a vital role in diabetes pathogenesis. As the current anti-diabetic drugs possess unprecedented side effects, traditional herbal medicine can be used an alternative therapy. The paramount challenge with the herbal formulation usage is the lack of standardized procedure, entangled with little knowledge on drug safety and mechanism of drug action. Heavy metal contamination is a major environmental hazard where plants tend to accumulate toxic metals like nickel, chromium and lead through industrial and agricultural activities. It becomes inappropriate to use these plants for phytotherapy as it may affect the human health on long term consumption. This review discuss about the environmental risk factors related to diabetes and better implication of medicinal plants in anti-diabetic therapy using network pharmacology. It is an in silico analytical tool that helps to unravel the multi-targeted action of herbal formulations rich in secondary metabolites. Also, a special focus is attempted to pool the databases regarding the medicinal plants for diabetes and associated diseases, their bioactive compounds, possible diabetic targets, drug-target interaction and toxicology reports that may open an aisle in safer, effective and toxicity-free drug discovery.

Abstract
There is an increasing trend of investigating natural bioactive compounds targeting pancreatic β-cells for the prevention/treatment of diabetes mellitus (DM). With the exploration of multiple mechanisms by which β-cells involve in the pathogenesis of DM, herbal medicines are gaining attention due to their multitasking ability as evidenced by traditional medicine practices. This review attempts to summarize herbal medicines with the potential for improvement of β-cell functions and regeneration as scientifically proven by in vivo/in vitro investigations. Furthermore, attempts have been made to identify the mechanisms of improving the function and regeneration of β-cells by herbal medicines. Relevant data published from January 2009 to March 2020 were collected by searching electronic databases “PubMed,” “ScienceDirect,” and “Google Scholar” and studied for this review. Single herbal extracts, polyherbal mixtures, and isolated compounds derived from approximately 110 medicinal plants belonging to 51 different plant families had been investigated in recent years and found to be targeting β-cells. Many herbal medicines showed improvement of β-cell function as observed through homeostatic model assessment-β-cell function (HOMA-β). Pancreatic β-cell regeneration as observed in histopathological and immunohistochemical studies in terms of increase of size and number of functional β-cells was also prominent. Increasing β-cell mass via expression of genes/proteins related to antiapoptotic actions and β-cell neogenesis/proliferation, increasing glucose-stimulated insulin secretion via activating glucose transporter-2 (GLUT-2) receptors, and/or increasing intracellular Ca2+ levels were observed upon treatment of some herbal medicines. Some herbal medicines acted on various insulin signaling pathways. Furthermore, many herbal medicines showed protective effects on β-cells via reduction of oxidative stress and inflammation. However, there are many unexplored avenues. Thus, further investigations are warranted in elucidating mechanisms of improving β-cell function and mass by herbal medicines, their structure-activity relationship (SAR), and toxicities of these herbal medicines.

Antihyperglycemic and Antilipidemic Properties of a Tea Infusion of the Leaves from Annona cherimola Miller on Streptozocin-Induced Type 2 Diabetic Mice. Molecules 2021; 26:molecules26092408. [PMID: 33919145 PMCID: PMC8122452 DOI: 10.3390/molecules26092408] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Revised: 04/15/2021] [Accepted: 04/18/2021] [Indexed: 01/02/2023] Open
Abstract
The antihyperglycemic and antilipidemic effects of the tea infusion extracts of leaves from Annona cherimola Miller (IELAc-0.5, IELAc-1.5, and IELAc-3.0) were evaluated on normoglycemic (NG) and streptozocin-induced diabetic (STID) mice. In the acute test, IELAc-1.5 at 300 mg/kg bodyweight (bw) exhibited antihyperglycemic activity on STID mice since the first hour of treatment. Then, its antidiabetic potential was analyzed in a subchronic evaluation. IELAc-1.5 was able to reduce the blood glucose level, glycated hemoglobin (HbA1c), cholesterol (CHO), and triglycerides (TG); high-density lipoprotein (HDL) showed an increase at the end of treatment. IELAc-1.5 did not modify the urine profile at the end of the evaluation, and neither toxicity nor macroscopic organ damage were observed in acute and subchronic assays. In addition, a major flavonol glycoside present in the tea infusion extracts was identified using high-performance liquid chromatography with diode array detection (HPLC-DAD). The analysis of the tea infusion extracts by HPLC revealed that rutin was the major component. This study supports the use of tea infusions from Annona cherimola for the treatment of diabetes and suggests that rutin could be responsible, at least in part, for their antidiabetic properties.

Abdulmalek SA, Fessal M, El-Sayed M. Effective amelioration of hepatic inflammation and insulin response in high fat diet-fed rats via regulating AKT/mTOR signaling: Role of Lepidium sativum seed extracts. JOURNAL OF ETHNOPHARMACOLOGY 2021; 266:113439. [PMID: 33017634 DOI: 10.1016/j.jep.2020.113439] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Revised: 09/21/2020] [Accepted: 09/28/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Obesity-induced insulin resistance and chronic inflammation appears to be the most frequent cause of diabetes and its related metabolic complications; in this way a new therapeutic approaches are needed to prevent the chronic obesity and insulin resistance. Lepidium sativum has been extensively used in traditional alternative medicine for cough, skin disease, liver disorder, diuretic, gastrointestinal problems, hair loss treatment, milk secretion during lactation as well as antioxidant, antihypertensive, anti-inflammatory, and antidiabetic activities. The hypoglycemic and hypolipidemic effect of Lepidium sativum have been observed by previous studies, but the underlying molecular mechanisms are unclear. AIM OF THE STUDY In this study, we investigated the beneficial effect of Lepidium sativum ethanol and aqueous seed extracts on obesity, oxidative, inflammatory, and insulin sensitivity changes in the liver tissue of high fat diet (HFD)-fed rats. The bioactive constituents responsible for these activities have been identified for both extracts using HPLC and GC-MS. MATERIALS AND METHODS Rats were fed HFD for 10 weeks. The obese rats were treated orally with the Lepidium sativum ethanol extracts (LSEE) at dose 200 and 400 mg/kg body weight (BW) and Lepidium sativum aqueous extracts (LSAE) at dose 200 mg/kg BW daily for 8 weeks. RESULTS The findings of the present study pointed out a significant increase in the hepatic transaminases, lipid profile, leptin, and hepatic oxidative stress with decreased antioxidant capacity of HFD-fed rats. Consistent with this depiction; we determined the up-regulation of liver inflammatory markers with a significant down-regulation of insulin signaling components phospho-insulin receptor (p-IR), p-AKT, p-mammalian target of rapamycin (p-mTOR), and p-p70S6K after consumption of HFD for 10 weeks that indicates a deterioration of insulin sensitivity. Interestingly, the phytochemical screening of LSEE and LSAE exhibited positive results for phenolic, flavonoid, lipid, and some bioactive components as well as the in vitro antioxidant activity of both extracts clearly demonstrated their high antioxidant activities. Notably, LSEE and LSAE displayed a wide range of biological features including anti-obesity, anti-inflammatory, and antioxidant properties. Both extracts significantly decreased high glucose, leptin, lipid profile, liver enzymes levels, and body weight. We also found that LSEE and LSAE significantly alleviated lipid peroxidation and restored the antioxidant enzymes to normal levels. In parallel, the intracellular phosphorylation of classical markers of insulin signaling cascade p-IR/p-AKT/p-mTOR/p-p70S6K was up-regulated in the hepatic tissues of LSEE and LSAE-treated groups. CONCLUSION This study provides evidence that LSEE and LSAE might be one promising dietary supplementation that could safely and effectively prevent the early metabolic alterations and weight gain caused by HFD further regulate the activation of insulin signaling pathway beside their powerful antioxidant and low-toxicity properties.

Abstract
ETHNOPHARMACOLOGY RELEVANCE Nowadays, there is an increase in global tendency to use medicinal plants as preventive and therapeutic agents to manage diabetes and its long-term complications such as cardiovascular disorders owing to their availability and valuable traditional background. AIM OF STUDY This review aims to introduce common medicinal plants, which have been demonstrated to have cardioprotective effects on diabetes and their mechanisms of action. MATERIALS AND METHODS Online literature databases, including Web of Sciences, PubMed, Science Direct, Scopus and Google Scholar were searched without date limitation by May 2020. The following keywords (natural products or medicinal plants or herbal medicine or herb or extract) and (diabetes or antidiabetic or hyperglycemic) and (cardiomyopathy or heart or cardioprotective or cardiac or cardio) were used, and after excluding non-relevant articles, 81 original English articles were selected. RESULTS The surveyed medicinal plants induced cardioprotective effects mostly through increasing antioxidant effects leading to attenuating ROS production as well as by inhibiting inflammatory signaling pathways and related cytokines. Moreover, they ameliorated the Na+/K + ATPase pump, the L-type Ca2+ channel current, and the intracellular ATP. They also reduced cardiac remodeling and myocardial cell apoptosis through degradation of caspase-3, Bax, P53 protein, enhancement of Bcl-2 protein expression as well as downregulation of TGFβ1 and TNFα expression. In addition, the extracts improved cardiac function through increasing EF% and FS% as well as restoring hemodynamic parameters. CONCLUSIONS The reviewed medicinal plants demonstrated cardioprotective manifestations in diabetes through intervention with mechanisms involved in the diabetic heart to restore cardiovascular complications.

Abstract
Type 2 diabetes (T2D) is a chronic disease with a growing prevalence worldwide. In addition to the conventional therapy, many T2D patients use phytotherapeutic preparations. In the present study, chemical composition, antioxidant, and α-glucosidase inhibiting activity of traditional antidiabetics from Croatian ethnomedicine (Achillea millefolium, Artemisia absinthium, Centaurium erythraea, Morusalba, Phaseolus vulgaris, Sambucus nigra, and Salvia officinalis) were assessed. The efficacy of water and 80% ethanol as extraction solvents for bioactive constituents was compared. HPLC analysis revealed that the prepared extracts were rich in phenols, especially rutin, ferulic, and chlorogenic acid. Antiradical (against DPPH and ABTS radicals), reducing (towards Mo6+ and Fe3+ ions), and enzyme inhibiting properties were in linear correlation with the content of phenolic constituents. Ethanolic extracts, richer in phenolic substances, showed dominant efficacy in those assays. Aqueous extracts, on the other hand, were better Fe2+ ion chelators and more active in the β-carotene linoleic acid assay. Extracts from S. officinalis and A. millefolium were particularly active antioxidants and α-glucosidase inhibitors. A. absinthium, another potent α-glucosidase inhibitor, contained chromium, a mineral that promotes insulin action. The investigated plants contained significant amounts of minerals useful in management of T2D, with negligible amounts of heavy metals deeming them safe for human use.

Abstract
Abstract
Background
Brassica nigra is a plant of Brassicaceae family, which possesses numerous medicinal values. Our present study is intended to assess the potential in vitro thrombolytic, anthelminthic, cytotoxic and in vivo anxiolytic properties of MCE of B. nigra flowers. MCE was fractioned for separating the compound on the basis of polarity by using chloroform, n-hexane and ethyl acetate solvent. Thrombolytic and anthelminthic activities were explained by collecting human erythrocytes and earthworms as test models, respectively. Anxiolytic activity was evaluated by elevated plus maze and hole board models while cytotoxic test was conducted through brine shrimp lethality bioassay.
Results
MCE revealed the presence of alkaloids, flavonoids, tannin, diterpenes, glycosides, carbohydrates, phenols, fixed oils and fat. In case of thrombolytic test, the MCE, CSF, ASF and n-HSF had produced maximum clot lysis activity at 5 and 10 mg/ml dose conditions. Two different concentrations (10 and 20 mg/ml) of MCE and its fractions showed significant (p < 0.05) anthelminthic activities in a dose-dependent manner. Significant anxiolytic activity was observed for all fractions which was comparable to the standard drug diazepam (p < 0.05). Again, the cytotoxic screening also presented good potentials for all fractions.
Conclusion
From the findings of present study, we can conclude that MCE of B. nigra flowers and its fraction possess significant anxiolytic, anthelmintic, anticancer and thrombolytic properties which may be a good candidate for treating these diseases through the determination of bio-active lead compounds.

Abstract
We investigated the antidiabetic activity of Pistacia terebinthus (PT) extracts in streptozotocin (STZ) induced diabetic rats. We used 40 Wistar albino male rats divided into five groups: control (C), diabetes (DM), diabetes + acarbose (DM + AC), diabetes + PT (DM + PT) and PT. DM was established by intraperitoneal injection of STZ. Immunohistochemistry revealed that STZ reduced insulin immunoreactivity in the pancreas of the diabetic rats. To the contrary, insulin immunoreactivity in the pancreatic β cells of PT treated diabetic rats was increased significantly. Decreased levels of blood glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), glucose, total triglyceride (TG), total cholesterol (TC), high density lipoprotein (HDL) and low density lipoprotein (LDL) were found in the PT supplemented diabetic group. Also, malondialdehyde (MDA) and antioxidant defense system enzyme levels were normalized in the DM + PT group. PT exhibited a protective effect on liver, kidney and pancreas that had been damaged by STZ induced DM.

Abstract
OBJECTIVES To investigate the cytotoxic potential of S. aethiopicus extracts in combination with chitosan and Pharmacel® 101, on two cell lines. METHODS Extracts were chemically characterised utilising UPLC-Q-TOF/MS, followed by determination of cell viability and membrane integrity. KEY FINDINGS Ethanol (EtOH) and diethyl ether (DiEt) extracts contained significant quantities of all chosen biomarker molecules; however, only two were scarcely quantifiable in aqueous extracts. Aqueous extracts did not induce any cytotoxic effects, whereas EtOH and DiEt extracts caused concentration-dependent decreases in cell viability and membrane integrity loss in both cell lines. Ensuing exposure to EtOH extracts at 50, 100 and 150 μg/ml, HepG2 cells were considered 15.5%, 12.5% and 32.8% apoptotic, whereas DiEt extracts caused 4.5%, 13.5% and 33.9% apoptotic cells. Exposure to EtOH and DiEt extracts at 50 μg/ml ensued in 20.2% and 21.3% apoptosis in Caco-2 cells; 100 μg/ml induced apoptosis in 19.9% and 10.3% of Caco-2 cells; whereas exposure to 150 μg/ml EtOH extracts caused 12.6% apoptosis compared to 11.7% induced by the DiEt extract. CONCLUSIONS None of the excipients caused any significantly altered cellular effects, indicating little chance for physicochemical interactions. Aqueous extracts did not possess any cytotoxic properties. However, it is clear that organic extracts caused apoptotic and necrotic cell death.

Evaluation of polyherbal ayurvedic formulation 'Peedantak Vati' for anti-inflammatory and analgesic properties. JOURNAL OF ETHNOPHARMACOLOGY 2019; 235:361-374. [PMID: 30703493 DOI: 10.1016/j.jep.2019.01.028] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/27/2017] [Revised: 08/19/2018] [Accepted: 01/26/2019] [Indexed: 06/09/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Peedantak Vati (PV) is a polyherbal ayurvedic formulation, which is regularly prescribed by the ayurvedic practitioner for the inflammatory disorders and joints pain in India. It is composed of 23 different herbs and minerals, described in ayurvedic text for their anti-inflammatory and analgesic properties. AIM OF THE STUDY To investigate anti-inflammatory and anti-nociceptive potential of 'Peedantak Vati' using in vitro and in vivo methods. MATERIALS AND METHODS In-vitro anti-inflammatory activity of PV was studied by estimating nitric oxide (NO) and LPS-induced pro-inflammatory cytokines IL-6 and TNF-α, using murine macrophage RAW264.7 and human monocyte THP-1 cell lines. PV's anti-inflammatory potential was studied in vivo using carrageenan-induced rat paw edema model. Similarly, anti-nociceptive property of PV was evaluated using hot plate, tail flick, formalin and writhing tests on CD-1 mice. Phytochemical profiling of hydro-alcoholic extract of PV was done using HPLC and HPTLC techniques to identify different marker compounds. These identified marker compounds were confirmed using LC-MS/MS analysis. RESULTS In vitro results strongly suggest that, PV significantly (p < 0.001) inhibited NO release and LPS-stimulated pro-inflammatory cytokines IL-6 and TNF-α, in murine RAW264.7 and human THP-1 cells. Further, PV demonstrated significant (p < 0.05) anti-inflammatory activity at different time points after carrageenan injection with maximum effect at 2 h (40.4 ± 5.2% at 400 mg/kg). Similarly, PV significantly (p < 0.05) decreased nociceptive pain, studied using hot plate, tail flick, formalin and writhing tests. Moreover, HPLC and HPTLC methods were developed for the standardization of PV. Five marker phytocompounds viz. rutin, caffeic acid, colchicine, withaferin A and curcumin were identified and quantified by HPLC and HPTLC methods. The presence of these phytoconstituents was confirmed by LC-MS/MS analysis. CONCLUSION The findings of the study strongly suggest that, the polyherbal ayurvedic formulation 'Peedantak Vati' possesses remarkable anti-inflammatory and analgesic property, providing potent alternative for currently available allopathic medicines such as non steroidal anti-inflammatory drugs (NSAIDs).

Abstract
The longan industry produces a large amount of byproducts such as pericarp and seed, resulting in environmental pollution and resource wastage. The present study was performed to systematically evaluate functional components, i.e., polyphenols (phenolics and flavonoids) and alkaloids, in longan byproducts and their bioactivities, including antioxidant activities, nitrite scavenging activities in simulated gastric fluid and anti-hyperglycemic activities in vitro. Total phenolic and total flavonoid contents in pericarp were slightly higher than those in seeds, but seeds possessed higher alkaloid content than pericarp. Four polyphenolic substances, i.e., gallic acid, ethyl gallate, corilagin and ellagic acid, were identified and quantified using high-performance liquid chromatography. Among these polyphenolic components, corilagin was the major one in both pericarp and seed. Alkaloid extract in seed showed the highest DPPH radical scavenging activity and oxygen radical absorbance capacity. Nitrite scavenging activities were improved with extract concentration and reaction time increasing. Flavonoids in seed and alkaloids in pericarp had potential to be developed as anti-hyperglycemic agents. The research result was a good reference for exploring longan byproducts into various valuable health-care products.

Abstract
Significance: Compounds derived from plants are gaining importance for the treatment of several diseases. Many plants from the Convolvulaceae family contain compounds that have demonstrated wound healing and antidiabetic activity. Such compounds can be effectively used as a part of treatments to promote wound healing in diabetics and used in combination with antimicrobial therapy to reduce the likelihood of drug resistance and allergic reactions. Novel strategies for developing herbal formulations such as nanoparticles and adhesive patches can improve the delivery of plant-based therapeutic agents. Recent Advances: Studies have confirmed the antidiabetic and wound healing activities of Merremia tridentata, Argyreia speciosa, and Ipomoea batatas, whereas Evolvulus alsinoides, Evolvulus nummularius, Argyreia cuneata, and Ipomoea carnea have wound healing activity. Critical Issues: Drug resistance is a major problem associated with antimicrobial therapy and can affect wound healing processes. Phytoconstituents can facilitate healing processes and reduce reliance on antibiotics. Future Directions: Plants from the Convolvulaceae family have had frequent traditional uses, and all plants selected for this study have antimicrobial, antidiabetic, and wound healing properties. Detailed phytochemical studies of these plants can help develop novel wound healing therapies.

Abstract
In the last decade, mass spectrometry has been widely employed in the study of diabetes. This was mainly due to the development of new, highly sensitive, and specific methods representing powerful tools to go deep into the biochemical and pathogenetic processes typical of the disease. The aim of this review is to give a panorama of the scientifically valid results obtained in this contest. The recent studies on glycation processes, in particular those devoted to the mechanism of production and to the reactivity of advanced glycation end products (AGEs, AGE peptides, glyoxal, methylglyoxal, dicarbonyl compounds) allowed to obtain a different view on short and long term complications of diabetes. These results have been employed in the research of effective markers and mass spectrometry represented a precious tool allowing the monitoring of diabetic nephropathy, cardiovascular complications, and gestational diabetes. The same approaches have been employed to monitor the non-insulinic diabetes pharmacological treatments, as well as in the discovery and characterization of antidiabetic agents from natural products. © 2018 Wiley Periodicals, Inc.

Dietary fatty acids from pomegranate seeds (Punica granatum) inhibit adipogenesis and impact the expression of the obesity-associated mRNA transcripts in human adipose-derived mesenchymal stem cells. J Food Biochem 2018; 43:e12739. [PMID: 31353555 DOI: 10.1111/jfbc.12739] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2018] [Revised: 10/10/2018] [Accepted: 11/04/2018] [Indexed: 11/30/2022]
Abstract
Obesity is a metabolic disorder that manifests into various forms. Recent studies have indicated that the pomegranate (Punica granatum) seed oil (PSO) has many biologically active components that help in controlling diet-induced obesity and insulin resistance. However, its impact on the adipogenic differentiation of human adipose-derived mesenchymal stem cells (HADMSC) remains unclear. Here we have attempted to study the anti-obesity potential of SHAMstat3pg, a fatty acid composite extracted from PSO. It is composed of three dietary fatty acids: punicic acid [(9Z,11E,13Z)-9,11,13-Octadecatrienoic acid], oleic acid [Cis-9-Octadecenoic acid], and linoleic acid [(9Z,12Z)-octadeca-9,12-dienoic acid]. In this study, we discuss the impact of the fatty acids on adipogenesis, inflammation, glucose uptake, and mitochondrial ATP production. The impact of SHAMstat3pg on the expression of various obesity-associated protein and mRNA transcripts in HADMSC was also analyzed. The results indicate that exposure to 10 µg/ml of SHAMstat3pg (24 hr) inhibited adipogenesis of HADMSC, ameliorated inflammation, attenuated ATP production, and glucose uptake. Also, the extract favorably regulated the mRNA expression of the studied obesity-associated gene transcripts. PRACTICAL APPLICATIONS: SHAMstat3pg has the potential to serve as a multi-targeted therapy for the management of obesity. This study demonstrated that the dietary fatty acids inhibited the differentiation of preadipocytes to adipocytes. SHAMstat3pg has also shown to have a favorable impact on the expression of the obesity-linked proteins and genes in HADMSC that are associated with adipogenesis, inflammation, satiety, energy intake/expenditure (central and peripheral signaling molecules). The study gives an overview of the vast number of genes impacted by the treatment with SHAMstat3pg paving the way for future studies to demonstrate the exact mode of action of how dietary fatty acids can help manage obesity, insulin resistance, and type 2 diabetes.

An in vivo study of the pharmacological activities of a methanolic acetate fraction of Pistia stratiotes L.: An ethno-medicinal plant used in Bangladesh. Animal Model Exp Med 2018; 1:221-227. [PMID: 30891568 PMCID: PMC6388050 DOI: 10.1002/ame2.12037] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2018] [Revised: 09/08/2018] [Accepted: 09/26/2018] [Indexed: 11/05/2022] Open
Abstract
BACKGROUND The present study covered an assessment of methanolic acetate fractions of Pistia stratiotes, commonly known as water lettuce, for analgesic, anti-inflammatory, and CNS depressant activities. METHODS The methanol acetate fractions were extracted from Pistia stratiotes and administered to the experimental animals as 200 and 400 mg/kg doses to determine the effect on acetic acid-induced writhing and formalin-induced licking and biting, for the assessment of analgesic activity. The anti-inflammatory assay was done using the carrageenan-induced hind paw edema method, while assessment of CNS depressant activity was done using the open field and hole cross tests. The effects were compared to standard reference drugs. RESULTS At both doses (200 and 400 mg/kg body weight), the methanolic acetate extract of P. stratiotes showed significant analgesic action (P < 0.05) against acetic acid-induced writhing. The extract was also found to give significant protection against licking and biting at both doses. The methanolic acetate extract of P. stratiotes showed a significant (P < 0.05) anti-inflammatory effect from 0 minutes up to 3 hours in the carrageenan-induced paw edema test. In the CNS depressant assay, the methanolic acetate extract showed significant (P < 0.05) depressant activity at both doses from 30 to 120 minutes in both the hole cross and open field tests. CONCLUSION Thus we can conclude that P. stratiotes extracts have significant analgesic, anti-inflammatory, and CNS depressant activity, compared to standard compounds, in an animal model.

Abstract
Globally, traditional medicine has long been used to address relatively common illness, mental ill health and during childbirth and post-natal care. However, traditional medicine is primarily provided by the private sector and it is unclear how far expenditures on traditional medicine contribute to household impoverishment. A life history method was used to understand the health seeking experience of 24 households over the last 60 years in Cambodia, a country with high out-of-pocket expenditures for health. The life histories suggest that traditional medicine in Cambodia has been undergoing a process of commercialization, with significant impacts on poor households. In the earlier lives of respondents, payments for traditional medicine were reported to have been flexible, voluntary or appropriate to patients’ financial means. In contrast, contemporary practitioners appear to seek immediate cash payments that have frequently led to considerable debt and asset sales by traditional medicine users. Given traditional medicine‘s popularity as a source of treatment in Cambodia and its potential to contribute to household impoverishment, we suggest that it needs to be included in a national conversation about achieving Universal Health Coverage in the country.

Abstract
The use of botanicals for maintaining good health and preventing diseases is undisputed. The claimed health benefits of natural health products and herbal medicines are based on traditional claims, positive results obtained in preclinical studies and early phase clinical trials that are not backed by safety and efficacy evidences approved by regulatory agencies. Although, the popularity of botanicals is growing, health care practitioners of modern medicine seldom recommend their use because of ill equipped database of their safety and potency. This review discusses problems that preclude botanicals from integrating into the mainstream contemporary therapeutics and cues that provide impetus for their realisation.

Abstract
Phytotherapy has long been a source of medicinal products and over the years there have been many attempts to use herbal medicines for the treatment of diabetes. Several medicinal plants and their preparations have been demonstrated to act at key points of glucidic metabolism. The most common mechanisms of action found include the inhibition of α-glucosidase and of AGE formation, the increase of GLUT-4 and PPARs expression and antioxidant activity. Despite the large amount of literature available, the actual clinical effectiveness of medicinal plants in controlling diabetes-related symptoms remains controversial and there is a crucial need for stronger evidence-based data. In this review, an overview of the medicinal plants, which use in the management of diabetes is supported by authoritative monographs, is provided. References to some species which are currently under increasing clinical investigation are also reported.

[PMID: 29629018 PMCID: PMC5882212 DOI: 10.11604/pamj.2017.28.232.12585] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2017] [Accepted: 11/06/2017] [Indexed: 11/11/2022] Open
Abstract
Complementary and alternative medicine is an integral component of primary healthcare in Kenya. This is because the infrastructural health setup in the country is inadequate in catering for all the medical needs of the population. This particularly holds true in the rural areas where many rural folk rely on products of herbal origin to offset their healthcare needs. More often than not these products are an elaborate cacophony of several different substances of biological origin and thus need personnel adept in their preparation. Sadly, due to loopholes in legislation and regulation, quacks have a field day in the practice. Moreover, the process of planting, harvesting, preparation and storage of herbs and related products dictates that a significant number of people will ultimately be involved in the whole process. This is likely to set the stage for manipulation and compromise of the safety, quality and efficacy of these products. This state of affairs appears unabated especially in the context of the current legal and regulatory framework governing herbal medicine use and practice in Kenya. Not only are these laws inadequate, they are shrouded in ambiguity, open to interpretation and the authorities mandated to implement them often end up performing duplicate roles. The aim of this review is to critique the legal and regulatory provisions governing herbal medicine use and practice in Kenya. In conclusion, laws and regulations meant to control herbal medicine use and practice in Kenya are wanting. Clear and definitive legislation on herbal medicine use and practice coupled with effective implementation by mandated institutions will go a long way in inspiring confidence to all stakeholders of herbal medicine.

Abstract
AIM As diabetes mellitus is multi-factorial disease, use of several oral hypoglycemic agents (OHAs) is the main stay of pharmacological treatment. The treatment has become more challenging and controversial as OHAs are heterogeneous in their mode of action that causes unwanted side effects. Complementary approaches such as use of medicinal plants and dietary polyunsaturated fatty acids (PUFA) with hypoglycemic and hypolipidemic activities are therefore imperative. A vast literature has independently documented the effects of OHAs, medicinal plants and PUFA for management of diabetes. In the present article, we have reviewed the current literature to describe the effects of commonly used OHAs, their mechanisms of action and reported controversies. The antidiabetic potential of herbs and/or formulations and omega-3 PUFA with its potential benefits and mode of action is also discussed. METHODS PUBMED, MEDLINE, Cochrane Library etc., were searched for relevant articles using appropriate terms (until February 2015). Human and animal studies were selected for the review. Data extraction was carried out by one author and checked by second author. RESULTS There is still controversy over the safety profile of OHAs. Medicinal herbs with hypoglycemic activities are increasingly sought because of its natural origin, active constituents and minimal side effects. The current literature suggests that supplementation with PUFA improves macro- and microvascular complications. CONCLUSION There is a need for best possible individualized treatment based on variations in biochemical parameters with combinational therapy of nutritional/herbal supplementations. Such a combination may be helpful for better management of diabetes and its complications.

Abstract
BACKGROUND Loss of white adipose tissue (WAT), associated with type 1 diabetes (DM1), contributes to increased chronic systemic inflammation. AIM The aim of this study was to investigate the effects of leucine supplementation and resistance training (RT) in attenuating WAT loss and improving inflammatory parameters and glucose metabolism in DM1 rats. METHODS Thirty-two male Wistar rats were distributed into four groups: DA (sedentary and supplemented with non-essential amino acids (NEAA)), DL (sedentary and supplemented with leucine), DTA (submitted to RT and supplemented with NEAA) and DTL (submitted to RT and supplemented with leucine). DM1 was induced by streptozotocin (STZ). An 8-week period of RT consisted of climbing a ladder with a progressively increased load, and supplementation was offered in the feed. RESULTS Glycemia, polyphagia and polydipsia were lower in DL, DTA and DTL groups compared with the DA group by approximately 20% ( p<.0001), 28% ( p=.004) and 64% ( p<.0001), respectively. Weight of total WAT and retroperitoneal adipose tissue (RPAT) were higher by approximately 21% ( p=.01) and 54% ( p=.0004), respectively, in DL, DTA and DTL groups compared with DA. However, gene expression of adiponectin and leptin in RPAT was only increased by RT (DTA and DTL) compared with DA and DL by approximately 93% ( p<.0001) and 78% ( p=.0002), respectively. Similarly, the levels of adiponectin in the serum, tissue IL-10 (RPAT) and serum IL-10 were only increased in DTA and DTL compared with DA and DL by approximately 31% ( p=.03), 45% ( p=.0009) and 35% ( p=.003), respectively. CONCLUSIONS Both interventions, isolated or together, reduced hyperglycemia and excessive loss of WAT, but RT was the main factor responsible for attenuating inflammation.

Abstract
Ethanol (95%) and dichloromethane : methanol (DCM : M, 1 : 1 v/v) bark extracts (BEs) and leaf extracts (LEs) of authenticated Ceylon cinnamon (CC) were studied for antiamylase, antiglucosidase, anticholinesterases, and antiglycation and glycation reversing potential in bovine serum albumin- (BSA-) glucose and BSA-methylglyoxal models in vitro. Further, total proanthocyanidins (TP) were quantified. Results showed significant differences (p < 0.05) between bark and leaf extracts for the studied biological activities (except antiglucosidase) and TP. BEs showed significantly high (p < 0.05) activities for antiamylase (IC50: 214 ± 2–215 ± 10 μg/mL), antibutyrylcholinesterase (IC50: 26.62 ± 1.66–36.09 ± 0.83 μg/mL), and glycation reversing in BSA-glucose model (EC50: 94.33 ± 1.81–107.16 ± 3.95 μg/mL) compared to LEs. In contrast, glycation reversing in BSA-methylglyoxal (EC50: ethanol: 122.15 ± 6.01 μg/mL) and antiglycation in both BSA-glucose (IC50: ethanol: 15.22 ± 0.47 μg/mL) and BSA-methylglyoxal models (IC50: DCM : M: 278.29 ± 8.55 μg/mL) were significantly high (p < 0.05) in leaf. Compared to the reference drugs used some of the biological activities were significantly (p < 0.05) high (BEs: BChE inhibition and ethanol leaf: BSA-glucose mediated antiglycation), some were comparable (BEs: BSA-glucose mediated antiglycation), and some were moderate (BEs and LEs: antiamylase, AChE inhibition, and BSA-MGO mediated antiglycation; DCM : M leaf: BSA-glucose mediated antiglycation). TP were significantly high (p < 0.05) in BEs compared to LEs (BEs and LEs: 1097.90 ± 73.01–1381.53 ± 45.93 and 309.52 ± 2.81–434.24 ± 14.12 mg cyanidin equivalents/g extract, resp.). In conclusion, both bark and leaf of CC possess antidiabetic properties and thus may be useful in managing diabetes and its complications.

Abstract
The purpose of this exploratory study was to investigate how nursing students in Indonesia and Scandinavia characterize a healthy person. Two hundred thirty-two nursing students from Indonesia, 50 students from Sweden, and 119 students from Norway participated by answering an open-ended question. Qualitative content analysis was used to identify patterns of health in a cultural and national context. The characteristics of a healthy person were summarized in the theme “external and inner balance,” which are intertwined because of the wholeness of self-image and appearance. The subcategories were having a strong and positive body image, feeling well and having inner harmony, following the rules of life, coping with challenges, and acting in unison with the environment. There were more similarities than differences between the Indonesian and Scandinavian nursing students’ understanding of being a healthy person. The difference is that the Scandinavian students mentioned individuality, whereas the Indonesian students referred to collective values.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Type 2 diabetes is the most common type of diabetes and its prevalence is rapidly increasing throughout the world. Modifications of lifestyle such as suitable diet and exercise programs along with pharmacotherapy and education of patients are beneficial therapies for patients with type 2 diabetes. The ethnopharmacological use of herbal medicines, many of them part of our diet as spices, vegetables and fruits, has been developed for the treatment of diabetes due to inexpensiveness, easy availability and few side effects. AIM OF THE STUDY Our aim is to present a review for researchers who are interested in the biologically active dietary plants traditionally utilized in the treatment of diabetes. MATERIALS AND METHODS Information was obtained from a literature search of electronic databases such as Google Scholar, Pubmed, Sci Finder and Cochrane. Common and scientific name of the fruits, vegetables, beverages, oils and spices and the words 'antidiabetic', 'hypoglycemic', 'anti-hyperglycemic', 'type 2 diabetes' were used as keywords for search. RESULTS Certain fruits and vegetables are functional foods and their consumption reduces the incidence of type 2 diabetes. Hypoglycemic effects of fruits and vegetables may be due to their inducing nature on pancreatic β-cells for insulin secretion, or bioactive compounds such as flavonoids, alkaloids and anthocyanins, which act as insulin-like molecules or insulin secretagogues. CONCLUSION This write-up covers hypoglycemic, anti-hyperglycemic and anti-diabetic activities of some dietary fruits, vegetables, beverages, oils and spices and their active hypoglycemic constituents. Including such plant species in the diet might improve management of type 2 diabetes.

[PMID: 28298260 PMCID: PMC5377522 DOI: 10.1016/j.jaim.2016.12.004] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2016] [Revised: 10/11/2016] [Accepted: 12/22/2016] [Indexed: 11/30/2022] Open
Abstract
Due to dearth of literature on the effect of herbal toothpaste on saliva and salivary constituents, the present study was undertaken to evaluate and compare the effect of three different herbal toothpastes with the focus on on salivary pH and salivary glucose. Forty five subjects in the age group of 19–21 years were randomly divided into 3 groups (15 in each group) and were randomly intervened with three different herbal toothpastes (Dant Kanti, Himalaya Complete Care and Vicco Vajradanti). Unstimulated saliva samples were collected before and after brushing and salivary glucose and pH levels were assessed at an interval of one week each for a period of 4 weeks starting from day 1. All the three toothpastes were effective in reducing the overall (p < 0.05) levels as well as levels of salivary glucose from pre-brushing to post-brushing at each interval (p < 0.05) and in increasing the overall levels as well as levels of salivary pH (p < 0.05) from pre-brushing to post-brushing at each interval. Herbal toothpastes were effective in reducing salivary levels of glucose and improving pH of the saliva.

Abstract
BACKGROUND The traditional use of Eugenia uniflora L. ("Pitanga") is reported due to several properties, which have often been related to its flavonoid content. OBJECTIVE The aim was to evaluate analytical procedures for quantification of total flavonoids content (TFCs) by ultraviolet-visible (UV-Vis) spectrophotometry in the herbal material (HM), crude extract (CE), and fractions from leaves of E. uniflora. MATERIALS AND METHODS The method for quantification of flavonoids after complexation with aluminum chloride (AlCl3) was evaluated: amount of sample (0.25-1.5 g); solvent (40%-80% ethanol); reaction time and AlCl3 concentration (2.5%-7.5%). The procedures by direct dilution (DD) and after acid hydrolysis (AH) were used and validated for HM and CE and applied to the aqueous fraction (AqF), hexane fraction, and ethyl acetate fractions (EAF). RESULTS The ideal conditions of analysis were ethanol 80% as solvent; 0.5 g of sample; λmax of 408 (DD) and 425 nm (AH); 25 min after addition of AlCl3 5%. The procedures validated for standards and samples showed linearity (R2 > 0.99) with limit of detection and limit of quantification between 0.01 and 0.17 mg/mL (rutin and quercetin); and 0.03 and 0.09 mg/mL (quercetin), for DD and AH, respectively. The procedures were accurate (detect, practice, and repair < 5% and recovery >90%), and stable under robustness conditions (luminosity, storage, reagents, and equipment). The TFCs in AqF and EAF were 0.65 g% and 17.72 g%, calculated as rutin. CONCLUSIONS UV-Vis methods for quantification of TFC in HM, CE, and fractions from leaves of E. uniflora were suitably validated. Regarding the analysis of fractions, the EAF achieved enrichment of about nine times in the content of flavonoids. SUMMARY The total flavonoids content (TFCs) of herbal material, crude extract, and fractions from Eugenia uniflora can be quantified by ultraviolet-visibleThe spectrophotometric methods (direct dilution and acid hydrolysis) were reproducible and able to quantify TFC in raw material and derivatives from leaves of E. unifloraHigher flavonoids content was observed in ethyl acetate fractions after enrichment. Abbreviations Used: HM: Herbal material, CE: Crude extract, AqF: Aqueous fraction, HF: Hexanic fraction, EAF: Ethyl acetate fraction, TFC: Total flavonoids content, HCl: Hydrochloric acid, DD: Direct dilution, AH: After hydrolysis, RSD: Relative standard, A.U.: Absorption units.

Abstract
BACKGROUND Polyherbalism, an alternative natural-based therapy for various disorders, has been quoted about 1,300 years before in Sharangdhar Samhita. Herbal-based combination therapy stages a vital role for the treatment of type 2 diabetes mellitus (T2DM) and associated complications. The present study aims at developing an Ayurvedic-based polyherbal formulation (ADPHF6) and the assessing its antidiabetic and antioxidant property. METHODS ADPHF6 polyherbal formulation was measured for phytochemical components by qualitative methods. The polyherbal formulation was quantitatively estimated for its phytochemical constituents, i. e. total phenol and flavonoid content. Further, the antioxidant property of ADPHF6 formulation was evaluated by 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) radical scavenging assay, hydrogen peroxide radical scavenging assay and metal chelating assay. α-Amylase and α-glucosidase inhibitory activities of polyherbal formulation were also assessed. ADPHF6 was further analysed for its protective antioxidant property against reactive oxygen species (ROS‾)-induced damage in human lymphocyte DNA and pUC19 plasmid. RESULTS ADPHF6 polyherbal formulation revealed the presence of phytochemical constituents such as alkaloids, flavonoids, phenols, tannins, terpenoids, saponins and cardiac glycosides in significant levels. Further, it also measured the higher levels of total phenols (473.3±3.05 mg/g) and flavonoid (664±5.29 mg/g) content. Polyherbal formulation also exhibited IC50 values of 49.9±0.15, 65.1±0.10 and 60.1±0.05 mg/mL for 2,2- diphenyl-1-picryl-hydrazyl-hydrate (DPPH), hydrogen peroxide (H2O2) and Fe2+ radical scavenging activities, respectively. ADPHF6 revealed an inhibitory activity (IC50) of 0.67±0.01 and 0.81±0.01 mg/mL for α-amylase and glucosidase, respectively. Pre-treated human peripheral blood lymphocytes with ADPHF6 aqueous extract illustrated enhanced protection against ROS-mediated damage as compared with post-treated groups. DNA nicking assay rendered protective activity against the OH¯ radical-induced DNA damage in supercoiled pUC19 plasmid. CONCLUSIONS Our present study demonstrates that ADPHF6 offers potent inhibitory activity against free radicals as well as digestive enzymes. However, studies should be conducted using in vivo model to further elucidate the effect against free radicals and its anti-hyperglycaemic activity in the management of non-insulin-dependent diabetes.

Abstract
Previous studies reveal that fibroblast growth factor 21 (FGF21) sensitizes insulin to achieve a synergy in regulating glucose metabolism. Here, we report that insulin sensitizes FGF21 in regulating both glucose and lipid metabolisms. db/db diabetic mice were subcutaneously administrated once a day for 6 weeks. Effective dose of insulin (1 U) could control blood glucose level of the db/db mice for maximum of 2 h, increased the body weight of the db/db mice and did not improve serum lipid parameters. In contrast, effective dose of FGF21 (0.5 mg/kg) could maintain blood glucose of the db/db mice at normal level for at least 24 h, repressed the weight gain of the mice and significantly improved lipid parameters. Ineffective doses of FGF21 (0.125 mg/kg) and insulin had no effect on blood glucose level of the db/db mice after 24 h administration, body weight or lipid parameters. However, combination of the two ineffective doses could maintain blood glucose level of the db/db mice for at least 24 h, suppressed weight gain and significantly improved lipid parameters. These results suggest that insulin sensitizes FGF21 in regulating both glucose and lipid metabolism. The results aimed to study the molecular basis of FGF21 sensitization indicates that combination of the two ineffective doses increased the mRNA expression of glut1, glut4, β-Klotho, sirt1, pgc-1α, ucp-1 and AKT phosphorylation, decreased fasn. The results demonstrate that insulin sensitizes FGF21 through elevating the phosphorylation of common gene Akt and amplifying FGF21 downstream signaling, including increasing expression of glut1 sirt1, pgc-1α, ucp-1, and decreasing fasn expression. In summary, we reports herein for the first time that insulin sensitizes FGF21 to achieve a synergy in regulating glucose and lipid metabolism. Along with previous studies, we conclude that the synergistic effect between FGF21 and insulin is realized through mutual sensitization.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Being one of the most common types of life threatening diseases in Southern Assam, India, the digestive system disorders (DSD) have gained much attention in recent decades. Traditional beliefs and inadequate income of mass population result in the use of alternative phytotherapies to treat the diseases. AIM OF THE STUDY The present paper documents the medicinal knowledge and utilization of plants for treatment of digestive system disorders in Southern Assam, India by Disease Consensus Index (DCI). It also determines the most suitable plant species used to treat digestive system disorders in the study area. MATERIALS AND METHODS The study was based on ethnomedicinal field survey covering a period of 1 year from 2014-2015. The ethnomedicinal information was collected by using semi-structured questionnaires from different traditional Bengali people having knowledge on medicinal plants. Collected data were analyzed by calculating DCI. RESULTS During the survey, 29 informants were interviewed and a total of 49 plants under 46 genera belonging to 33 families were listed. Data analysis revealed that Litsea glutinosa, Momordica charantia, Andrographis paniculata, Lawsonia inermis, Cleome viscosa, Psidium guajava, Ageratum conyzoides, Cuscuta reflexa, Cynodon dactylon and Carica papaya are the most prominent plants among the people of Southern Assam for treating DSD. CONCLUSION This explorative survey emphasizes the need to preserve and document the traditional healing practices for managing DSD inviting for more imminent scientific research on the plants to determine their efficacy as well as safety. With the help of statistical analysis (DCI), we propose 10 priority plants for DSD in present work. Systematic pharmacological study with these plants may contribute significant result.

Abstract
Background Leaf extracts of Scoparia dulcis, is used as a herbal remedy by diabetics worldwide. Fresh Scoparia dulcis porridge elicited a low glycaemic index (GI) and anti-hyperglycaemic effects when fed to diabetic Wistar rats. Commercially produced Scoparia dulcis porridge (SDC) elicited medium GI. Present study was aimed at studying the anti-diabetic effects of consumption of commercially produced S. dulcis porridge. Method A randomized crossover clinical trial with type 2 diabetic patients (n = 35) on medication, with mild and moderate diabetes [fasting blood glucose (FBG) 126–300 mg/dL, age 35–70 years] was conducted. Within the first three months (study period 1) group 1 was the test and group 2 was the control. Following a wash-out period, the two groups were crossed over (study period 2: group 1 – control; group 2 - test). Test group consumed commercially produced SDC for 3 days/week for three months and the control group any other food. At the onset and end of each study period glucose measurements [Fasting Blood Glucose (FBG), HbA1c], lipid measurements (total cholesterol, HDL-C, LDL-C, triglycerides, cholesterol ratios), toxicity parameters (liver enzymes, creatinine, CRP, eGFR) were analyzed by enzyme assay kit methods using a KONELAB 20XT auto analyzer. Significances between groups were analyzed by one way ANOVA (normal distribution) and Mann Whitney test (if the values were not normally distributed). Within group comparisons were carried out by Bonferroni post hoc test. Results During the crossover clinical trial HbA1c of group 1 decreased from 7.9 ± 0.5 to 6.5 ± 0.3 (p = 0.003) while HbA1c of group 2 decreased from 7.0 ± 0.3to 6.7 ± 0.3 while in the test group. Therefore, both test groups (1 and 2) elicited a decrease in HbA1c compared to respective control groups. Both test groups elicited a non significant decrease in FBG following the intervention (group 1 - from 174 ± 14 to 160 ± 10 mg/dL; group 2 - from 183 ± 13 to 160 ± 7 mg/dL). No significant differences (p >0.05) in insulin, cholesterol measurements (total cholesterol, LDL-C, HDL-C, triglycerides and cholesterol ratios) and atherogenic index between or within groups were observed. All other measurements (AST, ALT, ALP, creatinine, CRP, eGFR) were normal and not significantly different between or within groups. Conclusion Porridge made with SDC leaf extract decreased FBG and HbA1c (p >0.05) of type 2 diabetic patients. The porridge had no effect on cholesterol measurements and no toxicity was observed at the dose tested. Therefore, the SDC porridge can be recommended as a suitable meal for diabetic patients.

Abstract
INTRODUCTION Worldwide, plant based medicines are increasing in popularity due to perceptions of safety and efficacy. Herbalists in Kenya are widely consulted for the management of many diseases including Type 2 Diabetes Mellitus (T2DM). This study investigated the level of knowledge of the herbalists in management of T2DM. METHODS Purposive sampling was used to identify 4 herbalists working in the urban areas who actively manage T2DM. Key informant interviews were used to gather data about the management of T2DM. It was analyzed using a content thematic approach. RESULTS Diverse management methods which included both pharmacological and non- pharmacological were noted. Glycemic control was assessed with the help of a glucometer. In addition, presenting signs and symptoms were key in diagnosing T2DM. The herbalists used various herbs, minerals and animals as medicinal sources. The drugs were dispensed as decoctions with excipients being added appropriately. Adverse effects were recorded. The herbalists acknowledged that patients use both herbal and allopathic medicine together. A level of record keeping was observed but patient follow-up was poor. The cost of the herbal drugs was perceived to be excessive. CONCLUSION Some similarities exist in the management of T2DM between allopathic and traditional medicine practitioners. Training of herbalists is required to improve the quality of care given to patients.

Abstract
The genus Cyclopia, an indigenous South African fynbos plant used to prepare honeybush tea, contains phytoestrogenic compounds. An extract from C. subternata, SM6Met, displays three desirable estrogenic attributes for future development of a phytoestrogenic nutraceutical, namely, ERα antagonism, ERβ agonism, and also antagonism of E2-induced breast cancer cell proliferation. Activity-guided fractionation of SM6Met was used in an attempt to isolate and identify compounds conferring the desirable estrogenic profile to SM6Met. Initial liquid-liquid fractionation of SM6Met yielded a polar fraction (PF) and a non-polar fraction (NPF), with the desirable estrogenic attributes retained in the NPF. Subsequent high performance counter-current chromatography (HPCCC) fractionation of the NPF yielded three fractions (F1-F3). Interestingly, the fractions revealed separation of the previously demonstrated positive estrogenic attributes of the NPF into separate fractions, with F1 and F2 acting as ERα antagonists, only F2 inducing antagonism of E2-induced breast cancer cell proliferation and only F3 retaining robust ERβ agonist activity. In terms of major polyphenols, quantitative HPLC and liquid chromatography tandem mass spectrometry (LC-MS/MS) indicated that HPCCC fractionation resulted in a divergence of polyphenolic classes, with F1 emerging as the dihydrochalcone-rich fraction and F2 as the flavanone- and benzophenone-rich fraction, while the xanthones, flavones and phenolic acids were retained in F3. F3 was re-engineered into F3R by reassembling the major polyphenols identified in the fraction. F3R could, however, not replicate the effect of F3. In conclusion, although activity-guided fractionation results suggest that retention of all the desirable estrogenic attributes of the original SM6Met in one fraction is not an attainable goal, fractionation is a useful tool to enhance specific desirable estrogenic attributes.

Abstract
In the present study, Sugar Remedy, a polyherbal formulation (manufactured by Umalaxmi Organics Pvt Ltd, Jodhpur, Rajasthan, India) was evaluated for its antihyperglycemic, antihyperlipidemic, and antioxidant effects against normal and streptozotocin (STZ)-induced diabetic rats. Type II diabetes was induced in male Wistar rats by administration of a single intraperitoneal (IP) injection of STZ at a dose of 60 mg/kg. Effects of three different doses of Sugar Remedy suspension (185, 370, and 740 mg/kg/day, orally) and Metformin (500 mg/kg/day, orally) administered for 21 days were studied on parameters such as blood glucose, lipid profile, and antioxidant levels. Results were analyzed using one-way analysis of variance (ANOVA) followed by Dunnett's test. No significant changes were noticed in blood glucose, serum lipid levels, and kidney parameters in normal rats treated with Sugar Remedy suspension alone. The efficacy of Sugar Remedy as an antihyperglycemic, antihyperlipidemic, and antioxidant agent in STZ-induced diabetes was comparable to that of the standard, 500 mg/kg of Metformin. Present findings provide experimental evidence that Sugar Remedy has significant antihyperglycemic, antihyperlipidemic, and antioxidative effects in diabetic experimental rats. Hence, Sugar Remedy may be regarded as a promising natural and safe remedy for the prevention or delay of diabetic complications.
