Abstract
Semen persicae is the dried mature seeds of Prunus persica (L.) Batsch and P. davidiana (Carr.) Franch and is commonly used in traditional Chinese medicine (TCM) formulations because of its variety of biological effects. The present study aimed to evaluate the antioxidant activity and toxicity profiles of semen persicae extract (SPE) after determining the amygdalin content (4.95%) using HPLC. Regarding the in vitro antioxidant activity, SPE with 2 mg/mL concentration scavenged 1,1-diphenyl-2-picrylhydrazyl (DPPH), hydroxyl, and ABTS free radicals with rates of 51.78%, 55.47%, and 57.16%, respectively. The same concentration of SPE chelated 30.76% Fe2+. The in vitro cytotoxicity study revealed that SPE induced 92.45% cell viabilities of HEPG2 even at 2000 μg/mL. In the acute toxicity study, oral administration of SPE did not provoke mortality or any toxic signs at doses up to 2000 mg/kg bw. Repeated oral administration for 28 days at doses of 100, 300, and 600 mg/kg per day in rats did not show any toxicity signs or gross pathological abnormalities. The results of the present research provide basic reference data for SPE with a moderate effect on antioxidant activity and low toxicity for future screening of biological and pharmacological properties.

Effects of Ultra-High-Pressure Treatment on Chemical Composition and Biological Activities of Free, Esterified and Bound Phenolics from Phyllanthus emblica L. Fruits. Molecules 2024; 29:3181. [PMID: 38999132 PMCID: PMC11243165 DOI: 10.3390/molecules29133181] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2024] [Revised: 06/23/2024] [Accepted: 06/29/2024] [Indexed: 07/14/2024] Open
Abstract
Phyllanthus emblica L. fruits (PEFs) were processed by ultra-pressure (UHP) treatment and then extracted by the ultrasonic-assisted extraction method. The influence of UHP on the phenolic composition, enzyme inhibitory activity and antioxidant activity of the free, esterified, and bound phenolic fractions from PEFs were compared. UHP pretreatment of PEFs significantly increased the total phenolic and flavonoid contents (p < 0.05). A total of 24 chemical compositions were characterized in normal and UHP-treated PEFs by UHPLC-ESI-HRMS/MS. Compared with normal PEFs, these three different phenolic fractions had stronger antioxidant activities and inhibitory effects on the intracellular reactive oxygen species (ROS) production in H2O2-induced HepG2 cells (p < 0.05). The ROS inhibition might be due to an up-regulation of the expressions of superoxide dismutase (SOD) and glutathione (GSH) activities. In addition, these three different phenolic fractions also significantly inhibited the activities of metabolic enzymes, including α-glucosidase, α-amylase and pancreatic lipase. This work may provide some insights into the potential economics and applications of PEFs in food and nutraceutical industries.

Abstract
In current study antioxidant, antidiabetic, antimicrobial, anticholinesterase, and human carbonic anhydrase I, and II (hCA I and II) isoenzymes inhibition activities of Astrodaucus orientalis different parts were investigated. Achetylcholinesterse (AChE) and butyrylcholinesterse (BChE) inhibitory activities of octyl acetate were determined via molecular docking. Quantitative assessment of specific secondary metabolites was conducted using LC-MS/MS. An examination of chemical composition of essential oils was carried out by GC-MS/MS. A thorough exploration of plant's anatomical characteristics was undertaken. The highest phenolics level and DPPH antioxidant capacity were seen in root and fruit. Fruit essential oil demonstrated the highest AChE inhibition (44.13±3.61 %), while root dichloromethane sub-extract had the best inhibition towards BChE (86.13±2.58 %). Cytosolic hCA I, and II isoenzymes were influentially inhibited by root oil with 1.974 and 2.207 μM IC50 values, respectively. The most effective extracts were found to be root all extract/sub-extracts (except water) against C. tropicalis and C. krusei strains with MIC value 160>μg/mL. Sabinene (29.4 %), α-pinene (20.2 %); octyl acetate (54.3 %); myrcene (28.0 %); octyl octanoate (71.3 %) were found principal components of aerial parts, roots, flowers, and fruits, respectively. Flower essential oil, fruit dicloromethane and ethyl acetate exhibited potent α-glucosidase inhibitory activity with 900, 40, and 937 μg/mL IC50 values, respectively.

Abstract
The world's population is in a demographical transition, with an increase in the number of older adults and prevalence of diseases related to aging. This study evaluated in vitro the potential of using Durvillaea incurvata extract (extracted using ultrasound-assisted extraction) to inhibit key enzymes associated with the development of age-related diseases. Our results show that an extract extracted via ultrasound-assisted extracted, as well as an extract conventional extracted from Durvillaea incurvata, presented antidiabetes potential by exhibiting inhibitory activity against α-glucosidase (91.8 ± 1.0% and 93.8 ± 0.3%, respectively, at 500 µg/mL) and α-amylase (42.2 ± 1.4% and 61.9 ± 0.9%, respectively, at 1500 µg/mL) enzymes related to starch digestion and postprandial glycemic response. Also, the extracts showed inhibitory activity against the enzymes acetylcholinesterase (51.5% and 50.8%, respectively, at 500 µg/mL) and butyrylcholinesterase (32.8% and 34.4%, respectively, at 0.5 mg/mL), the biomarkers associated with Alzheimer's disease, and angiotensin-converting enzyme (98.7 ± 7.4% and 93.0 ± 3.4%, respectively, at 2.0 mg/mL), which is key in the regulation of vascular tone and blood pressure and helps to prevent the development of hypertension. In conclusion, the extract of Durvillaea incurvata obtained from ultrasound-assisted extraction has the potential to prevent the development of age-related pathologies such as diabetes, Alzheimer's disease, and hypertension.

Abstract
This study examined the effects of methanol extract and its sub-extracts from Epilobium angustifolium on α-glucosidase and α-amylase activity. Secondary metabolites and amino acids were quantified using LC-MS/MS. Dichloromethane sub-extract displayed the highest activity and was chosen for further investigation. Despite the widespread use of E. angustifolium, genotoxicity studies were conducted to assess its safety. Dichloromethane significantly inhibited α-glucosidase (IC50 =17.340 μg/mL), making it approximately 293 times more effective than acarbose. Six known compounds, including gallic acid (1), a mixture of quercetin-3-O-α-galactoside (2a) and quercetin-3-O-α-glucoside (2b), quercetin-3-O-α-glucuronic acid (3), quercetin-3-O-α-rhamnoside (4), and kaempferol-3-O-α-rhamnoside (5) were identified. Quercetin-3-O-α-rhamnoside exhibited the highest inhibition of α-glucosidase (IC50 =1735±85 μM), making it 3.70 times more effective than acarbose. Dichloromethane also showed significant antigenotoxic activity against mutagenesis induced by NaN3, 9-AA, 4-NPD, and MNNG. Gallic acid was found in the highest abundance (13253.6931 ng/mL) in the methanolic extract. Furthermore, L-Aspartic acid was the most concentrated amino acid (363.5620 nmol/mL) in the methanolic extract.

Abstract
Heavy metal contamination especially lead (Pb) causes a serious threat to global public health. In the current study, we explored the protective and regulating effects of Emblica officinalis polysaccharide (EOP) in the liver against Pb-induced toxicity. According to our findings, EOP decreased the Pb-induced pathological lesions of liver and overall weight index in mice (p < 0.05). Following treatment with EOP, the levels of biological biomarkers for liver hepatic function (i.e., ALT and AST) were significantly decreased (p < 0.01) in a dose-dependent manner, consisted with histopathological changes. The key proteins involved in hepatic oxidative stress and apoptosis, including Nrf2, HO-1, Bcl-2, and Bax were quantified, which indicated EOP as an effective approach in protecting against the liver injury. Moreover, EOP treatment ameliorated the negative changes of liver metabolic profile (i.e., metabolites concentrations and metabolic patterns). In conclusion, EOP could protect the liver against oxidative stress and apoptosis induced by Pb poisoning, associated with the efficacy of ameliorating the negative changes in liver metabolic profile. Hence, the current findings recommend EOP as an efficient way for alleviating liver injury in lead poisoning.

Abstract
Ferula tingitana L. is a high perennial plant and its leaf is an alternate arrangement and yellow, and its flowers are unisexual like other Apiaceae. It has been used as a spice and for various medicinal purposes in the Mediterranean region. The paper reports antidiabetic, antimicrobial, anticholinesterase, antioxidant, and genotoxic activities of leaves, flowers, stems, and fruits methanol extracts of F. tingitana. Also, quantitative determination of some secondary metabolites was also analyzed by LC-MS/MS. Moreover, chemical composition of essential oils was analyzed. Consequently, anatomical, and morphological properties of plant were investigated. Germacrene D (23.6%), 1,3,5-trimethylbenzene (18.4%), and α-pinene (50.0%) were found as the main compounds in flower, leaf, and stem oils, respectively. The cortex in stem, pedicel, and fruit is characterized by angular collenchyma cells and a distinct cambium layer. 6 compounds (quinic acid, fumaric acid, keracyanin chloride, cyanidin-3-O-glucoside, chlorogenic acid, hesperidin) were observed in samples. Leaf extract showed anticholinesterase activity. Leaf and flower extracts showed the highest % inhibition value on ABTS·+ and DPPH•. Leaf extract has the strongest antioxidant effect because it is rich in total phenolic contents. All extracts of F. tingitana were found generally effective against C. albicans. Stem extract was found effective against E. coli and flower extract was found more effective against S. enterica and C. albicans. Bacterial genotoxicity results showed that extracts did not have genotoxic activity on tester strains S. typhimurium and E. coli WP2uvrA. Thus, it revealed that extracts were genotoxic-ally safe at applied concentrations up to 3 mg/plate.

Abstract
Gagea genus, which is native to the Mediterranean and Black Sea regions, has attracted significant attention due to its biodiversity and potential health benefits. In this study, the biochemical composition and biological activities of methanol extracts from various parts of G. taurica were investigated, along with their anatomical and morphological characteristics. The best antimicrobial activity was found to be MeOH extracts of corm and leaf against several Candida strains with MIC=640 μg/mL. The highest level of phenolics together with significant results of antioxidant activities were observed in flowers extracts. The α-amylase inhibition assay results showed that the highest inhibition percentage was observed with acarbose (59 %), followed by leaf extract (43 %). Leaf exhibited the most effective inhibitory activity in AChE inhibition assay, whereas flower demonstrated the most significant inhibitory activity in BChE inhibition assay. Hesperidin was found as 1621.0001 ng/ml value in flower extract and 283.9339 ng/ml value leaf.

Abstract
Ulcerative colitis (UC) is a chronic inflammatory disease significantly impacting patients' lives. This study aimed to elucidate the alleviating effect of ethyl acetate extract (TBEA) from Terminalia bellirica fruit on UC and to explore its mechanism. TBEA was the fraction with the best anti-inflammatory activity screened using in vitro anti-inflammatory assays, and HPLC initially characterized its composition. The mice model of ulcerative colitis was established after free drinking of 2.5% dextran sulfate sodium for six days, and the experimental group was treated with 50 mg/kg and 100 mg/kg TBEA for seven days. We found that TBEA significantly alleviated symptoms in UC mice, including a physiologically significant reduction in disease activity index and pathological damage to colonic tissue. TBEA dramatically slowed down oxidative stress and inflammatory process in UC mice, as evidenced by decreasing myeloperoxidase and malondialdehyde activities and increasing glutathione and catalase levels by reducing the concentrations of IL-6, IL-1β, TNF-α, and NO in UC mice, as well as by regulating key proteins in the IL-6/JAK2/STAT3 pathway. Meanwhile, TBEA maintained intestinal homeostasis by regulating intestinal flora structure. Our study provides new ideas for developing TBEA into a new drug to treat UC.

Abstract
This study aimed to investigate the chemical composition and antidiabetic properties of cultivated Hyoscyamus albus L. The ethanol extract was analyzed using LC-MS/MS, and 18 distinct phenolic compounds were identified. Among these, p-coumaric acid (6656.8 ± 3.4 µg/g), gallic acid (6516 ± 1.7 µg/g), luteolin (6251.9 ± 1.3 µg/g), apigenin (6209.9 ± 1.1 µg/g), and rutin (5213.9 ± 1.3 µg/g) were identified as the most abundant polyphenolic molecules. In the in vitro antidiabetic experiment, the ability of the plant extract to inhibit α-glucosidase and α-amylase activities was examined. The results indicated that the extract from H. albus L. exhibited a higher inhibitory effect on α-amylase compared to α-glucosidase, with an IC50 of 146.63 ± 1.1 µg/mL and 270.43 ± 1.1 µg/mL, respectively. Docking simulations revealed that luteolin, fisetin, and rutin exhibited the most promising inhibitory activity against both enzymes, as indicated by their high contrasting inhibition scores. To further investigate the in vivo antidiabetic effects of H. albus L., an experiment was conducted using STZ-induced diabetic mice. The results demonstrated that the plant extract effectively reduced the levels of cholesterol and triglycerides. These findings suggest that H. albus L. may have therapeutic potential for managing hyperlipidemia, a common complication associated with diabetes. This highlights its potential as a natural remedy for diabetes and related conditions.

Abstract
Background and purpose Bhamrung-Lohit (BRL) remedy is a traditional Thai medicine (TTM). There are few reports of biological activity, the activity of its constituent plants, or quantitative analytical methods for the content of phytochemicals. In this study, we investigated antioxidant, anti-inflammatory activity, and total phenolic and flavonoid content and validated a new analytical method for BRL. Experimental approach Antioxidant activity was evaluated by a 2,2-diphenyl-1-picrylhydrazyl (DPPH and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging. The cellular antioxidant activity was evaluated by inhibition of the superoxide anion (O2●-) production from HL-60 cells and anti-inflammatory activity by inhibition of nitric oxide production in RAW264.7 cells. The total phenolic and flavonoid contents were analyzed using the Folin-Ciocalteu method and an aluminum chloride colorimetric assay, respectively. Validated analytical procedures were conducted according to International Conference on Harmonization (ICH) guidelines. Findings/Results An ethanolic extract of BRL exerted potent DPPH radical scavenging activity and moderate antioxidant and anti-inflammatory activity. Caesalpinia sappan exerted the greatest effect and the highest content of total phenolics and flavonoids. The HPLC method validated parameters that complied with ICH requirements. Each peak showed selectivity with a baseline resolution of 2.0 and precision was less than 2.0% CV. The linearity of all compounds was > 0.999 and the recovery % was within 98.0%-102.0%. The validated results demonstrated specificity/selectivity, linearity, precision, and accuracy with appropriate LOD and LOQ. Conclusion and implication BRL remedy, a TTM demonstrated antioxidant and anti-inflammatory properties. This study is the first report on the biological activity and the validation of an HPLC method for BRL remedy.

Abstract
Oil-Gan, also known as emblica, is the fruit of the genus Phyllanthus emblica L. The fruits are high in nutrients and display excellent health care functions and development values. The primary aim of this study was to investigate the activities of ethyl acetate extract from Phyllanthus emblica L. (EPE) on type 1 diabetes mellitus (T1D) and immunoregulatory activities in non-obese diabetes (NOD) mice with spontaneous and cyclophosphamide (Cyp)-accelerated diabetes. EPE was vehicle-administered to spontaneous NOD (S-NOD) mice or Cyp-accelerated NOD (Cyp-NOD) mice once daily at a dose of 400 mg/kg body weight for 15 or 4 weeks, respectively. At the end, blood samples were collected for biological analyses, organ tissues were dissected for analyses of histology and immunofluorescence (IF) staining (including expressions of Bcl and Bax), the expression levels of targeted genes by Western blotting and forkhead box P3 (Foxp3), and helper T lymphocyte 1 (Th1)/Th2/Th17/Treg regulatory T cell (Treg) cell distribution by flow cytometry. Our results showed that EPE-treated NOD mice or Cyp-accelerated NOD mice display a decrease in levels of blood glucose and HbA1c, but an increase in blood insulin levels. EPE treatment decreased blood levels of IFN-γ and tumor necrosis α (TNF-α) by Th1 cells, and reduced interleukin (IL)-1β and IL-6 by Th17 cells, but increased IL-4, IL-10, and transforming growth factor-β1 (TGF-β1) by Th2 cells in both of the two mice models by enzyme-linked immunosorbent assay (ELISA) analysis. Flow cytometric data showed that EPE-treated Cyp-NOD mice had decreased the CD4+ subsets T cell distribution of CD4+IL-17 and CD4+ interferon gamma (IFN-γ), but increased the CD4+ subsets T cell distribution of CD4+IL-4 and CD4+Foxp3. Furthermore, EPE-treated Cyp-NOD mice had decreased the percentage per 10,000 cells of CD4+IL-17 and CD4+IFNγ, and increased CD4+IL-4 and CD4+Foxp3 compared with the Cyp-NOD Con group (p < 0.001, p < 0.05, p < 0.05, and p < 0.05, respectively). For target gene expression levels in the pancreas, EPE-treated mice had reduced expression levels of inflammatory cytokines, including IFN-γ and TNF-α by Th1 cells, but increased expression levels of IL-4, IL-10, and TGF-1β by Th2 cells in both two mice models. Histological examination of the pancreas revealed that EPE-treated mice had not only increased pancreatic insulin-expressing β cells (brown), and but also enhanced the percentage of Bcl-2 (green)/Bax (red) by IF staining analyses of islets compared with the S-NOD Con and the Cyp-NOD Con mice, implying that EPE displayed the protective effects of pancreas β cells. EPE-treated mice showed an increase in the average immunoreactive system (IRS) score on insulin within the pancreas, and an enhancement in the numbers of the pancreatic islets. EPE displayed an improvement in the pancreas IRS scores and a decrease in proinflammatory cytokines. Moreover, EPE exerted blood-glucose-lowering effects by regulating IL-17 expressions. Collectively, these results implied that EPE inhibits the development of autoimmune diabetes by regulating cytokine expression. Our results demonstrated that EPE has a therapeutic potential in the preventive effects of T1D and immunoregulation as a supplementary.

Antioxidant, Anti-Inflammatory, and Anti-Cancer Properties of Amygdalin Extracted from Three Cassava Varieties Cultivated in Benin. Molecules 2023; 28:4548. [PMID: 37299029 PMCID: PMC10254302 DOI: 10.3390/molecules28114548] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 05/23/2023] [Accepted: 05/30/2023] [Indexed: 06/12/2023] Open
Abstract
Given that cancer is a disease that is rampant in the world and especially in Africa, where the population has enormous difficulty treating it, plants are a safer and less expensive alternative. Cassava is a plant species valued in Benin because of its numerous medicinal and nutritional virtues. This study evaluated the biological activities of amygdalin from the organs of three cassava varieties most commonly produced in Benin (BEN, RB, and MJ). HPLC analysis was used to quantify amygdalin in cassava organs and derivatives. Phytochemical screening was performed to determine secondary metabolite groups. DPPH and FRAP methods were used to assess antioxidant activity. Cytotoxicity of the extracts was tested on Artemia salina larvae. The anti-inflammatory activity was evaluated in vivo in an albino mouse paw edema model induced by 5% formalin. The anticancer activity was evaluated in vivo on Wistar rats rendered cancerous by 1,2-dimethylhydrazine (DMH) using 5-fluorouracil as a reference molecule. The results showed that the organs of all three-cassava varieties contained glycosides, flavonoids, saponosides, steroids, tannins, coumarins, and cyanogenic derivatives. Young stems and fresh cassava leaves had the highest amygdalin concentrations, with 11,142.99 µg 10 g-1 and 9251.14 µg 10 g-1, respectively. The Agbeli derivative was more concentrated in amygdalin, with a content of 401.56 µg 10 g-1 than the other derivatives. The antioxidant activity results showed that the amygdalin extracts were DPPH radical scavengers with IC50 values ranging from 0.18 mg mL-1 to 2.35 mg mL-1. The cytotoxicity test showed no toxicity of the extracts toward shrimp larvae. Administration of amygdalin extracts from the leaves of BEN and MJ varieties prevents inflammatory edema. The percentages of edema inhibition varied between 21.77% and 27.89%. These values are similar (p > 0.05) to those of acetylsalicylic acid (25.20%). Amygdalin extract of the BEN variety significantly (p < 0.0001) reduces edema. Both BEN extracts inhibited cancer induction with DMH. In preventive and curative treatments, rats fed with amygdalin extracts showed low anti-cancer activity under the effect of DMH and a significant difference in biochemical results. Thus, the organs of all three cassava varieties studied have secondary metabolites and good antioxidant activity. The leaves contain high levels of amygdalin and can be used as anti-inflammatory and anticancer agents.

Abstract
The anti-inflammation effect of aqueous Phyllanthus emblica L. extract (APE) and its possible underlying mechanism in dextran sulfate sodium (DSS)-induced mice chronic colonic inflammation were studied. APE treatment significantly improved the colitic symptoms, including ameliorating the shortening of the colon, increasing the DSS-induced body weight loss, reducing the disease activity index, and reversing the condition of colon tissue damage of mucus lost and goblet cell reduction. Overproduction of serum pro-inflammatory cytokines were suppressed by the treatment of APE. Gut microbiome analysis showed that APE remodeled the structure of gut bacteria in phylum and genus levels, upregulating the abundance of phylum Bacteroidetes, family Muribaculaceae, and genus Bacteroides and downregulating the abundance of phylum Firmicutes. The reshaped gut microbiome caused metabolic functions and pathway change with enhanced queuosine biosynthesis and reduced polyamine synthesis pathway. Colon tissue transcriptome analysis further elucidated APE-inhibited mitogen-activated protein kinase (MAPK), cytokine-cytokine receptor interaction, and tumor necrosis factor (TNF) signaling pathways and the expressions of the genes that promote the progress of colorectal cancer. It turned out that APE reshaped the gut microbiome and inhibited MAPK, cytokine-cytokine receptor interaction, and TNF signaling pathways as well as the colorectal-cancer-related genes to exert its colitis protective effect.

Emblica officinalis mitigates intestinal toxicity of mice by modulating gut microbiota in lead exposure. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2023; 253:114648. [PMID: 36812873 DOI: 10.1016/j.ecoenv.2023.114648] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Revised: 02/05/2023] [Accepted: 02/11/2023] [Indexed: 06/18/2023]
Abstract
Lead (Pb) contamination has been affecting public health for decades. As a plant-derived medicine, the safety and effectiveness of Emblica officinalis (E. officinalis) fruit extract has been emphasized. The current study focused on mitigating the adverse effects of lead (Pb) exposure in reducing its toxicity worldwide. According to our findings, E. officinalis significantly improved weight loss and colon length shortening (p < 0.05 or p < 0.01). The data of colon histopathology and serum levels of inflammatory cytokines indicated a positive impact to the colonic tissue and inflammatory cell infiltration in a dose-dependent manner. Moreover, we confirmed the expression level improvement of tight junction proteins (TJPs), including ZO-1, Claudin-1, and Occludin. Furthermore, we found that the abundance of some commensal species necessary for maintaining homeostasis and other beneficial function decreased in Pb exposure model, while a remarkable reversion impact was noticed on the intestinal microbiome composition in the treatment group. These findings were consistent with our speculations that E. officinalis could mitigate the adverse effects caused by Pb in alleviating intestinal tissue damage, intestinal barrier disruption, and inflammation. Meanwhile, the variations in gut microbiota might drive the fulfilling current impact. Hence, the present study could provide the theoretical basis for mitigating intestinal toxicity induced by Pb exposure with the help of E. officinalis.

Abstract
Scilla siberica subsp. armena is known as Siberian Squill which is naturally distributed in Lebanon-Syria, Transcaucasus, and Turkey. It is a perennial bulbous plant with a short vegetation period from March to May. In this study, the antimicrobial, antioxidant, α-amylase, and α-glucosidase inhibitory activities of corm, leaf, and flower methanolic extracts were examined. The anatomy and morphology of the plant organs were investigated by light and electron microscopes. The anatomy of S. siberica subsp. armena was investigated for the first time by electron microscopy in this study. The corm, leaf, and flower methanolic extracts were assessed against E. coli ATCC 8739, S. aureus ATCC 6538, B. subtilis ATCC 19,659, C. albicans ATCC 10,231, C. krusei ATCC 14,243, and C. tropicalis ATCC 750. Among the extracts, that obtained from the blue pollen showed the best antimicrobial activity against C. tropicalis ATCC 750 strain with a MIC value of 312.5 µg/mL. The highest phenolic content was determined in leaf extract with 53.59211 µg GAE/mg extract value. The extract showed the best anti-lipid peroxidation activity with 376.69 µg/mL value. Using DPPH· and ABTS·+ tests, it was determined that the flower and leaf extracts have the best activity (IC50 = 756.13 μg/mL and IC50 = 94.07 μg/mL, respectively). The flower extract exhibited α-glucosidase inhibitory activity with the IC50 value of 5239 µg/mL. Based on the presented results of the in vitro antimicrobial, antioxidant, and antidiabetic activities of the S. siberica subsp. armena, we suggest that natural compounds from S. siberica subsp. armena are of potential use for the improvement of an antidiabetic, antioxidant, and antimicrobial agent.

[PMID: 36557959 PMCID: PMC9783910 DOI: 10.3390/molecules27248827] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 12/01/2022] [Accepted: 12/06/2022] [Indexed: 12/15/2022] Open
Abstract
Managing diabetes is challenging due to the complex physiology of the disease and the numerous complications associated with it. As part of the ongoing search for antidiabetic chemicals, marine algae have been demonstrated to be an excellent source due to their medicinal properties. In this study, Ulva reticulata extracts were investigated for their anti-diabetic effect by examining its inhibitory effects on α-amylase, α-glucosidase, and DPP-IV and antioxidant (DPPH) potential in vitro and its purified fraction using animal models. Among the various solvents used, the Methanolic extract of Ulva reticulata (MEUR) displayed the highest antidiabetic activity in both in vitro and in vivo; it showed no cytotoxicity and hence was subjected to bioassay-guided chromatographic separation. Among the seven isolated fractions (F1 to F7), the F4 (chloroform) fraction exhibited substantial total phenolic content (65.19 μg mL-1) and total flavonoid content (20.33 μg mL-1), which showed the promising inhibition against α-amylase (71.67%) and α-glucosidase (38.01%). Active fraction (F4) was further purified using column chromatography, subjected to thin-layer chromatography (TLC), and characterized by spectroscopy techniques. Upon structural elucidation, five distinct compounds, namely, Nonane, Hexadecanoic acid, 1-dodecanol, Cyclodecane methyl, and phenol, phenol, 3,5-bis(1,1-dimethylethyl) were identified. The antidiabetic mechanism of active fraction (F4) was further investigated using various in vitro and in vivo models. The results displayed that in in vitro both 1 and 24 h in vitro cultures, the active fraction (F4) at a concentration of 100 μg mL-1 demonstrated maximum glucose-induced insulin secretion at 4 mM (0.357 and 0.582 μg mL-1) and 20 mM (0.848 and 1.032 μg mL-1). The active fraction (F4) reduces blood glucose levels in normoglycaemic animals and produces effects similar to that of standard acarbose. Active fraction (F4) also demonstrated outstanding hypoglycaemic activity in hyperglycemic animals at a dose of 10 mg/kg B.wt. In the STZ-induced diabetic rat model, the active fraction (F4) showed a (61%) reduction in blood glucose level when compared to the standard drug glibenclamide (68%). The results indicate that the marine algae Ulva reticulata is a promising candidate for managing diabetes by inhibiting carbohydrate metabolizing enzymes and promoting insulin secretion.

Abstract
Hemerocallis citrina Borani (daylily) has various health benefits. However, the structural characterization and hypoglycemic effects of its polysaccharide remain unclear. Here, we first report for the first time, the effects of subcritical water extraction temperature on bioactivity of Hemerocallis citrina Borani polysaccharide (HCBP). HCBP extracted at 160 °C had better scavenging ability of free-radical and pancreatic lipase inhibition. This study aimed to investigate the structural characterization and anti-diabetic effects of aforementioned HCBP. HCBP was separated into three fractions using a DEAE-Sepharose Fast Flow. HCBP-1 was the major component with lower molecular weight, HCBP-2 was the least abundant component, HCBP-3 was the component with higher uronic acid and molecular weight. HCBP treatment significantly decreased the concentrations of fasting blood glucose, insulin, total cholesterol, triglyceride, and low density lipoprotein, as well as improved glucose intolerance and insulin resistance in type 2 diabetes mellitus (T2DM) rats. HCBP also protected the kidneys and pancreatic organs by histopathology and immunohistochemical analyses in T2DM rats. In addition, HCBP significantly increased the antioxidant enzymes activities and decreased the level of malonaldehyde to alleviated the oxidative stress injury. The results indicate HCBP extracted by subcritical water is promising functional food ingredients and could be used in T2DM treatment.

Abstract
Phyllanthus emblica L. fruits were extracted by a hot water assistant with ultrasonication to obtain aqueous Phyllanthus emblica L. extract (APE). The ameliorating functional dyspepsia (FD) effect of a low dose (150 mg/kg) and a high dose (300 mg/kg) of APE was exhibited by determining the gastrointestinal motility, gastrointestinal hormones, and gut microbiome shifts in reserpine induced FD male balb/c mice. APE increased the gastrointestinal motility including the gastric emptying (GE) rate and small intestinal transit (SIT) rate. The level of serum gastrointestinal hormones such as motilin (MTL) and gastrin (GAS) increased, and the vasoactive intestinal peptide (VIP) level decreased after the administration of APE. Furthermore, the gut microbiome analysis demonstrated that APE could regulate the microbiome structure and restore homeostasis by elevating useful bacterial abundance, while simultaneously decreasing harmful bacterial abundance. This study demonstrated the ameliorating FD effect of APE and its potential efficacy in curing functional gastrointestinal disorders and maintaining a healthy digestive tract.

Abstract
Black soybean (BS) is a nutritious legume that is high in proteins, essential amino acids, dietary fiber, vitamins, minerals, anthocyanins, phenolic acids, isoflavones, and flavones. Traditional approaches for extracting BS bioactive compounds are commonly employed because they are simple and inexpensive, but they use toxic solvents and have lower yields. As a result, new extraction techniques have been developed, such as microwave, ultrasound, and enzyme-assisted extraction. Modern approaches are less harmful to the environment, are faster, and produce higher yields. The major anthocyanin in the BS seed coat was discovered as cyanidin-3-O-glucoside, accounting for nearly 75% of the total anthocyanins. BS and its seed coat also contains phenolic acids (p-hydroxybenzoic, gallic, vanillin, syringic acid), isoflavones (daidzein, glycitein and genistein), flavones, flavonols, flavanones, and flavanols. Bioactive compounds present in BS exhibit antioxidant, anti-cancerous, anti-diabetic, anti-obesity, anti-inflammatory, cardio and neuroprotective activities. The characterization and biological activity investigation of these bioactive compounds has provided researchers and food manufacturers with valuable information for developing functional food products and nutraceutical ingredients. In this review, the nutritional makeup of BS is reviewed, and the paper seeks to provide an insight of bioactive compound extraction methods as well as bioactive compounds identified by various researchers. The biological activities of BS extracts and their potential applications in food products (noodles), biodegradable films (pH sensitive film), and therapeutic applications (wound healing and anti-inflammation) are also discussed in the study. Therefore, BS have enormous potential for use in developing functional foods and nutraceutical components. This is the first review of its sort to describe and explain various extraction methodologies and characterization of bioactives, as well as their biological activity recorded in diverse works of literature, making it possible for food manufacturers and scientists to get a quick overview.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The fruits of Phyllanthus emblica Linn or Emblica officinalis Gaertn (Phyllanthaceae), (FPE) commonly known as Indian gooseberry or Amla, gained immense importance in indigenous traditional medicinal systems, including Ayurveda, for its medicinal and nutritional benefits. It is used to cure several diseases such as common cold, fever, cough, asthma, bronchitis, diabetes, cephalalgia, ophthalmopathy, dyspepsia, colic, flatulence, hyperacidity, peptic ulcer, erysipelas, skin diseases, leprosy, hematogenesis, inflammation, anemia, emaciation, hepatopathy, jaundice, diarrhea, dysentery, hemorrhages, leucorrhea, menorrhagia, cardiac disorders, and premature greying of hair. AIM OF THE STUDY In the present review, we presented a comprehensive analysis of the ethnopharmacology, bioactive composition, and toxicity of P. emblica to identify the gap between research and the current applications and to help explore the trends and perspectives for future studies. MATERIALS AND METHODS We collected the literature published before April 2021 on the phytochemistry, pharmacology, and toxicity of FPE. Literature in English from scientific databases such as PubMed, ScienceDirect, Wiley, Springer, and Google Scholar, books. These reports were analyzed and summarized to prepare this review. The plant taxonomy was verified by "The Plant List" database (http://www.theplantlist.org). RESULTS AND CONCLUSION s: FPE have been used as a rich source of vitamin C, minerals, and amino acids. Several bioactive molecules were isolated and identified from FPE such as tannins, flavonoids, saponins, terpenoids, alkaloids, ascorbic acid etc. The in vitro and in vivo pharmacological studies on FPE revealed its antimicrobial, antioxidant, anti-inflammatory, anti-diabetic, anticancer, radioprotective, hepatoprotective, immunomodulatory, hypolipidemic, anti-venom, wound healing, HIV-reverse transcriptase effect. Toxicological studies on fruits indicated the absence of any adverse effect even at a high dose after oral administration. CONCLUSIONS Although FPE showed remarkable therapeutic activities against several diseases such as diabetes, cancer, inflammation, hepatitis B virus, and malaria, there were several drawbacks in some previous reports including the lack of information on the drug dose, standards, controls, and mechanism of action of the extract. Further in-depth studies are required to explain the mechanism of action of the extracts to reveal the role of the bioactive compounds in the reported activities.

Abstract
Diabetes mellitus (DM) and its complications pose a major public health threat which is approaching epidemic proportions globally. Current drug options may not provide good efficacy and even cause serious adverse effects. Seeking safe and effective agents for DM treatment has been an area of intensive interest. As a healing system originating in Tibet, Traditional Tibetan Medicine (TTM) has been widely used by Tibetan people for the prevention and treatment of DM and its complications for hundreds of years. Tibetan Materia Medica (TMM) including the flower of Edgeworthia gardneri (Wall.) Meisn., Phyllanthi Fructus, Chebulae Fructus, Huidouba, and Berberidis Cortex are most frequently used and studied. These TMMs possess hypoglycemic, anti-insulin resistant, anti-glycation, lipid lowering, anti-inflammatory, and anti-oxidative effects. The underlying mechanisms of these actions may be related to their α-glucosidase inhibitory, insulin signaling promoting, PPARs-activating, gut microbiota modulation, islet β cell-preserving, and TNF-α signaling suppressive properties. This review presents a comprehensive overview of the mode and mechanisms of action of various active constituents, extracts, preparations, and formulas from TMM. The dynamic beneficial effects of the products prepared from TMM for the management of DM and its complications are summarized. These TMMs are valuable materia medica which have the potential to be developed as safe and effective anti-DM agents.

Abstract
Wheat bran is a rich source of phenolic compounds, and the health benefits of phenolic compounds depend on its bioaccessibility. The release behavior and functional properties of phenolic compounds in different particle size wheat bran during in vitro digestion were investigated. Coarse wheat bran (CWB, 1110.39 μm) was milled by airflow impact mill to produce medium wheat bran (MWB, 235.68 μm), fine wheat bran (FWB, 83.73 μm) and superfine wheat bran (SWB, 19.16 μm). The reduction in particle size increased the release of phenolic compounds, mainly ferulic acid, after digestion. The free p-coumaric acid content in SWB was nearly five times higher than that in CWB, MWB and FWB due to the complete destruction of aleurone cell walls. Moreover, SWB showed higher bioaccessible phenolic compounds content (65.51%) than CWB. The improved phenolic bioaccessibility increased the antioxidant capacities and carbohydrate-digestive enzymes inhibitory activities of SWB and significantly reduced its starch digestibility.

Abstract
Elaeagnus angustifolia L. (Elaeagnaceae) is an important medicinal plant associated with numerous pharmacological activities. Its leaves are used as a therapeutic agent in traditional medicinal systems to treat diabetes. However, the active compounds responsible for the beneficial effects of E. angustifolia remain unclear. In this study, we determined the bioactive profile of E. angustifolia leaves using open column chromatography and semi-preparative HPLC. Further, we sought to determine its α-glucosidase and α-amylase inhibitory activities, and its DPPH and ABTS radical-scavenging activities. Four undescribed flavonol glycosides, igdoside A-D, and four known glucosides were isolated from the ethyl acetate and n-butanol extracts of E. angustifolia leaves. Thereafter, the compound structures were identified using spectroscopic methods, including NMR and mass spectrometry. Of the compounds extracted, kaempferol-3-O-(6″-trans-p-coumaroyl)-β-D-glucopyranoside (trans-tiliroside), exhibited the highest α-glucosidase inhibitory activity with an IC50 value of 2128 ± 63 μM compared to the positive control, acarbose (IC50 = 6561 ± 207 μM). trans-Tiliroside was also found to exhibit potent scavenging activity against the ABTS radical, with an IC50 value of 5 ± 0 μM, compared to the positive controls, trolox (31 ± 1 μM) and α-tocopherol (50 ± 1 μM). In addition, isorhamnetin-3-O-β-D-galactopyranoside (IC50 = 6 ± 0 μM) and astragalin (IC50 = 6 ± 0 μM) showed similar ABTS radical-scavenging activity as trans-tiliroside. Based on HPLC, the content of trans-tiliroside was 9.69% in the ethyl acetate extract, 1.04% in decoction, 0.34% in 70% methanol extract, and 0.23% in infusion. None of the extracts and compounds showed α-amylase inhibition or DPPH-scavenging activity.

Triphala Rasayana is mentioned in Ayurveda, comprising fruits of three plant species viz. Phyllanthus emblica L. (P. emblica), Terminalia chebula Retz (T. chebula), and Terminalia bellirica Roxb (T.bellirica). Triphala Rasayana has been utilized in various traditional medicine systems, viz., Ayurveda, Siddha, and Unani. Traditionally Rasayana based drugs are utilized in different kinds of diseases without pathophysiological associations as indicated by current medication. Various medicinal attributes of Triphala Rasayana include antioxidant, anticancer, antidiabetic, antimicrobial, immunomodulatory, and anticataract and is also considered as a pillar for gastrointestinal treatment, specifically in functional gastrointestinal disorders (FGIDs). Due to Rasayana's accessible mode of administration, availability, and affordability, there is an increase in its global acceptance. AIM OF REVIEW This review article summarizes the scientific validation, traditional uses, bioactive compounds, and ethnopharmacological properties of Triphala Rasayana. It also documents recent data on in vivo and in vitro pharmacological studies and clinical effects of Triphala Rasayana. MATERIAL AND METHOD A literature review is carried out using PubMed, ScienceDirect, Scopus, web of science, Ayush Research Portal, and Clinical Trials Registry-India. In addition to an electronic search, traditional ayurvedic texts and books were used as sources of information. RESULTS Traditionally, "Triphala Rasayana" is classified as a tridoshic rasayana and one of the most well-studied ayurvedic Rasayana. It showed various pharmacological activities such as anticancer, antioxidant, antibacterial, immunomodulatory, cardioprotective, and antidiabetic. Besides this, Rasayana has reported ethnopharmacological activities such as antimicrobial, anticataract, wound healing, and radioprotection. It has shown a good impact on the gastrointestinal tract (GIT) system with the reported pharmacological activities in gastrointestinal disorders such as constipation, gastric ulcer, and inflammatory bowel disease (IBD). Phytochemical studies of Triphala Rasayana revealed chemical constituents like gallic acid, ellagic acid, chebulic acid, chebulinic acid, methyl gallate, emblicanin A, and emblicanin B. Additionally, clinical studies found Triphala Rasayana to be effective against diabetes, constipation, and obesity. CONCLUSION The present review revealed that Triphala Rasayana may treat a diverse range of diseases, especially GIT disorders. Considering the beneficial properties of Triphala Rasayana and it's proven non-toxic nature could be a source of rejuvenation in contemporary healthcare. Nevertheless, its clinical data effectively provided precious signals to correlate ayurvedic biology and modern medicine.

Abstract
Neuropathy is a common complication of diabetes affecting a large number of people worldwide. Triphala churna is a formulation mentioned in Ayurveda-a traditional system of medicine. It is a simple powder formulation consisting of powders of three fruits, Emblica officinalis L., Terminalia bellirica (Gaertn.) Roxb. and Terminalia chebula Retz. Individual components of Triphala churna have anti-diabetic and antioxidant activities. Hence, this study was designed to evaluate the effect of Triphala churna on diabetic neuropathy. Diabetes was induced with streptozotocin (STZ, 55 mg/kg, i. p.) in rats. Animals were grouped and treated orally with Triphala churna at a dose of 250, 500, and 1,000 mg/kg after 6 weeks of diabetes induction for the next 4 weeks. At the end of study, parameters such as body weight, plasma glucose level, motor nerve conduction velocity were determined. The effect of Triphala churna on thermal hyperalgesia, mechanical hyperalgesia, and mechanical allodynia was also determined at the end of study. The plasma cytokine levels like TGF-β1, TNF-α, and IL-1β were determined by ELISA assay. Histopathology study of the sciatic nerve was studied. Western blotting was performed to study the expression of neuronal growth factor.Treatment with Triphala churna showed a significant reduction in plasma glucose and a significant rise in body weight. Triphala treatment significantly increased the motor nerve conduction velocity and decreased the thermal and mechanical hyperalgesia, as well as mechanical allodynia. The treatment significantly inhibited levels of circulatory cytokines like TGF-β1, TNF-α, and IL-1β. Histopathology study confirmed the neuroprotective effect of Triphala churna. The expression of NGF was significantly increased in sciatic nerves after treatment with Triphala churna. From the results, it can be concluded that Triphala churna delays the progression of neuropathy in diabetic rats.

Abstract
The fruits of Terminalia bellirica (Gaertn.) Roxb. (TB) are used as a multi-use therapeutic herbal product in the Tibetan medicinal system and are prescribed as a general health tonic in the traditional Ayurvedic medicinal system. It has been demonstrated that these fruits have a variety of pharmacological activities, including anti-tumor, anti-oxidative, anti-inflammatory, hepatoprotective and immunoregulatory effects, etc. However, the therapeutic effects of tannins in TB on HCC and the underlying mechanisms remain uncharacterized. In the current study, we aimed to identify the anti-tumor effect of tannins in TB by employing a H22 xenograft mouse model and by performing cell-based in vitro studies with the assistance of the network pharmacology analysis. The crude extract of TB was purified to yield total tannin fraction (TB-TF), and our results found that TB-TF significantly inhibited the tumor growth of H22 xenografts in mice by inducing apoptosis and reducing angiogenesis. A total of 90 compounds were then identified in TB-TF by UPLC-MS/MS, and 27 were found in serum after oral administration of TB-TF in mice. The network pharmacology analysis based on these absorbed components was performed and, along with experimental evidence, it revealed that the ERBB, PI3K-Akt, and MAPK signaling pathways may be involved in the anti-tumor effect of TB-TF on HCC. Furthermore, we suggested that TB-TF effectively modulated the immunosuppressive tumor microenvironment in H22 xenograft mice. In summary, our study demonstrated that TB-TF could be developed as a functional food, which is not only a promising anti-cancer reagent but also a potential candidate with bright prospects for the emerging trends of immunotherapy for HCC.

Abstract
BACKGROUND Obesity and type 2 diabetes mellitus are the most extended current chronic diseases and also Alzheimer pathology which is a progressive degenerative neurological disorder. Therefore, finding effective enzyme inhibitors responsible for the development of these diseases are essential. Therefore, the aim of this study was to investigate the impact of fruit purée (Cydonia oblonga, Ziziphus jujube and Malus domestica) and pomegranate juice cultivar ('Mollar de Elche' and 'Wonderful') of dried pomegranate sheets (DS) on the inhibition of enzymes associated with metabolic (α-amylase, α-glucosidase, and pancreatic lipase activity), and neurological disorder (acetylcholinesterase and butyrylcholinesterase activity). Quality properties (colour coordinates, texture properties and sensory characteristics) of DS were also studied. In addition, it was researched the effect of storage conditions (4 months at 4 and 20 °C) on phenolic content. RESULTS DS from jujube had the highest antioxidant capacity and were characterized by the highest storage stability with respect to phenolic compounds. The α-amylase and α-glucosidase half maximal inhibitory concentration (IC50 , in mg mL-1 ) inhibition of DS ranged from 107 to 216 and from 55.2 to values indicating no effect, respectively. The inhibition toward pancreatic lipase (IC50 < 5 mg mL-1 ), acetylcholinesterase (ranged 9.15-22.2%) and butyrylcholinesterase (ranged 20.6-48.6%) was increased with the presence of total flavonoids and hydroxycinnamic acids content (identifying mainly in DS from quinces). It is noteworthy that none of the samples presented off-flavour notes, supporting the high quality of the products. CONCLUSION DS can be an innovative supplement to a diet as a snack used in the prevention of neurological changes and disorders of carbohydrate and lipid metabolism. © 2020 Society of Chemical Industry.

Abstract
This work describes a novel approach for the synthesis of (−)-epigallocatechin gallate (EGCG) palmitate by a chemical-synthesis method, where the elevated stability of the EGCG derivative is achieved. Various parameters affecting the acylation process, such as the base, solvent, as well as the molar ratio of palmitoyl chloride, have been studied to optimize the acylation procedure. The optimized reaction condition was set as follows: EGCG/palmitoyl chloride/sodium acetate was under a molar ratio of 1:2:2, with acetone as the solvent, and the reaction temperature was 40 °C. Under the optimized condition, the yield reached 90.6%. The EGCG palmitate (PEGCG) was isolated and identified as 4′-O-palmitoyl EGCG. Moreover, the stability of PEGCG under different conditions was proved significantly superior to EGCG. Finally, PEGCG showed better inhibition towards α-amylase and α-glucosidase, which was 4.5 and 52 times of EGCG, respectively. Molecular docking simulations confirmed the in vitro assay results. This study set a novel and practical synthetic approach for the derivatization of EGCG, and suggest that PEGCG may act as an antidiabetic agent.

Antioxidant, anti-inflammatory and hepatoprotective activities of Terminalia bellirica and its bioactive component ellagic acid against diclofenac induced oxidative stress and hepatotoxicity. Toxicol Rep 2020; 8:44-52. [PMID: 33391996 PMCID: PMC7772792 DOI: 10.1016/j.toxrep.2020.12.010] [Citation(s) in RCA: 43] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2020] [Revised: 11/07/2020] [Accepted: 12/10/2020] [Indexed: 12/19/2022] Open
Abstract
Long term usage and overdose of diclofenac (DCF), an anti-inflammatory drug is known to cause oxidative stress and liver injury. The present study reports the antioxidant, anti-inflammatory and hepatoprotective activities of Terminalia bellirica (Tb) fruit aqueous and ethyl acetate extracts and its bioactive compound ellagic acid (EA) against DCF-induced toxicity. in vitro antioxidant activities were measured by ABTS and FRAP assays while anti‐inflammatory activity was assessed by the albumin denaturation method. The adverse effects of DCF and hepatoprotective potential of Tb extracts and EA were assessed in serum and liver tissue of rats after oral administration for 21 days. Silymarin was used as standard hepatoprptective agent for comparison. Hepatic markers analyzed in serum included ALP, GPT, GOT, LDH, γ-glutamyl transferase, total protein, creatinine, and uric acid while superoxide dismutase (SOD) and catalase (CAT) were analyzed in liver tissue. The EA exhibited superior ABTS radical scavenging, FRAP, and anti-inflammatory activities as compared to fruit extracts. DCF treatment led to rise in the levels of most of the serum hepatic markers with decline in total serum protein as well as SOD and CAT in liver tissue. The supplementation of extracts, EA and silymarin in DCF treated rats significantly reduced the adverse effects of DCF on serum and tissue markers. Histopathology of the liver indicated that extracts and EA significantly decreased the degree of liver fibrosis. The hepatoprotective ability of EA was comparable to the silymarin but activity of Tb fruit extracts was little lower. Among fruit extracts ethyl acetate extract exhibited better activity than aqueous extract. The results revealed that ellagic acid and T. bellirica fruit extracts have potential to mitigate oxidative stress and hepatotoxicity produced by long term use of diclofenac.

Abstract
BACKGROUND Aceclofenac (ACF), a widely used nonsteroidal anti-inflammatory drug, has been associated with a number of severe cases of clinical hepatotoxicity. Terminalia bellirica, an evergreen tree, is known to have several ethnomedicinal uses including antioxidant and hepatoprotective effects. Hence T. bellirica fruit extracts and its phytoconstituent ellagic acid (EA) are expected to provide protection against oxidative stress and liver damage produced by long-term use of ACF.
AIM To evaluate the antioxidant and hepatoprotective activities of T. bellirica fruit extracts and EA against ACF-induced toxicity in albino Wistar rats.
METHODS The in vitro antioxidant activities of T. bellirica fruit ethyl acetate and aqueous extracts were measured by metal ion chelation and nitric oxide radical scavenging assays. The in vivo antioxidant and hepatoprotective effects of T. bellirica extracts (200 mg/kg) and EA (40 mg/kg) in ACF-induced hepatotoxic rats were assessed in serum and liver tissue after oral administration for 21 d. Silymarin (40 mg/kg) was used as a standard control. Oxidative stress markers in the blood (ferric reducing ability of plasma and lipid peroxidation inhibition) and liver tissues (superoxide dismutase, catalase and malondialdehyde) were analyzed using standard protocols. Liver function markers such as alkaline phosphatase, glutamic pyruvic transaminase, glutamic oxaloacetic transaminase, lactate dehydrogenase, γ-glutamyl transferase, creatinine, total protein, and uric acid were evaluated in rat serum.
RESULTS The T. bellirica fruit ethyl acetate extract exhibited superior metal ion chelating and nitric oxide radical scavenging abilities during in vitro antioxidant assays as compared to aqueous extracts. Oral administration of ACF in rats (15 mg/kg) for 21 d produced oxidative stress and adversely affected liver function suggesting liver injury. Treatment with extracts (ethyl acetate and aqueous), EA and silymarin accounted for a significant reduction in the adverse effects of ACF on oxidative stress and liver function markers in serum and hepatic tissue in rats. Histopathological evaluation of the liver indicated that the extracts and EA significantly decreased the degree of liver damage. The in vivo efficacy of EA was higher than T. bellirica fruit extracts. Of these extracts, ethyl acetate extract revealed comparatively better antioxidant and hepatoprotective activity.
CONCLUSION Ellagic acid and T. bellirica fruit extracts exhibited considerable hepatoprotective and antioxidant activities in long-term ACF-treated rats.

Abstract
In this paper, we report the synthesis of novel 1 H-pyrano[2,3- d]pyrimidine-2,4(3 H,5 H)-dione derivatives 5(a–j) by a facile multicomponent reaction. The structures of all the newly synthesized compounds were characterized by different spectroscopic techniques including infrared, nuclear magnetic resonance (1H and 13C) and mass spectral analysis. All the new compounds were assessed for their in vitro α-amylase and α-glucosidase enzyme inhibitory potential. The results of the assays revealed that all compounds showed different enzyme inhibition activities. The concentration required to inhibit enzyme activity is less in the case of α-glucosidases than for α-amylases, that is, the synthesized compounds are more potent in arresting α-glucosidase enzyme activity.

Abstract
Arabinoxylan (AX) has many beneficial health effects that are closely related to its structural characteristics. The current study aimed to investigate the effects of molecular weight (Mw) and degree of substitution (DS) on the antioxidant and hypoglycemic activities of triticale bran AX and its hydrolysates in vitro. At low and similar Mw, the antioxidant activity of AX was inversely proportional to its DS. When DS was close, the antioxidant activity of AX was inversely proportional to its Mw at high DS, but the opposite result was found at low DS. As for the hypoglycemic performance, when DS was similar, the hypoglycemic activity of AX was proportional to its Mw. At low and similar Mw, the α-glucosidase inhibitory ability and glucose adsorption ability of AX was positively correlated with DS, whereas the α-amylase inhibitory ability and glucose delayed absorption ability showed the opposite results. Mw and DS had significant effects on the antioxidant and hypoglycemic activities of AX, and these two factors often need to be combined to explain the varied effects under different conditions.

Abstract
BACKGROUND Terminalia bellirica (Gaertn.) Roxb. is one of the oldest medicinal herbs of India, Pakistan, Nepal, Bangladesh and Sri Lanka as well as South-East Asia. Its medicinal utility has been described in the different traditional medicinal systems, such as Ayurveda, Unani, Siddha, and traditional Chinese medicine. PURPOSE The present study is aimed at providing a comprehensive overview on the traditional medicinal use, major phytoconstituents, biological and pharmacological activities and related mechanisms of actions and clinical studies of T. bellirica. Another objective is to describe current limitations and future direction of T. bellirica-related research. METHODS PubMed, ScienceDirect, Scopus, Cochrane Library, and EBOSCO host databases were selected to explore literature published between 1980 and 2020 (till March). Keywords used in various combinations comprised of Terminalia bellirica, phytoconstituents, health effects, pharmacological activities, molecular targets, in vitro, in vivo, clinical studies, and disease prevention. RESULTS A broad spectrum in vitro and in vivo studies suggested various biological and pharmacological effects, including antioxidant, anti-inflammatory, immunomodulatory, antimicrobial, hepatoprotective, renoprotective, antidiabetic, anti-hyperlipidemic, and anticancer activities. Diverse bioactivities of T. bellirica have been ascribed to the presence of many bioactive phytochemicals, such as glucoside, tannins, gallic acid, corilagin, ellagic acid, ethyl gallate, galloyl glucose, chebulagic acid, and arjunolic acid. CONCLUSION Preclinical and clinical studies have suggested that T. bellirica plant and its phytoconstituents have immense potential for prevention and treatment of various diseases. Additional in vivo studies and clinical trials are warranted to realize the complete medicinal attributes of this plant.

Abstract
Type II diabetes mellitus is a common and costly disease worldwide, characterized by hyperglycemia. Alpha (α)-amylase and α-glucosidase are important targets in diabetes therapy. Inhibition of these enzymes may lessen hyperglycemia, preventing diabetic complications. Oxidative stress is another factor involved in the disease's etiology. In the present study, we investigated antidiabetic profiles of the various extracts and phytochemicals of Rumex acetosella. Since the plant has been traditionally used for the antidiabetic purposes. α-amylase and α-glucosidase inhibitory studies in addition to DPPH•, ABTS•+, NO 2 - radical scavenging, and phosphomolybdate antioxidant assays were performed to evaluate the antidiabetic property. Specifically, the ethanol and ethanol-water extracts remarkably inhibited α-glucosidase than that of acarbose, unlike their slight/no inhibition on α-amylase. Convincing α-glucosidase inhibitory and antioxidant potential of alcohol-including extracts verified the ethnobotanical use of R. acetosella as an antidiabetic agent. PRACTICAL APPLICATIONS: The incidence of Type II DM is rising globally. Reducing hyperglycemia holds great importance to prevent devastating outcomes of diabetic complications. Ethnobotanical use of natural sources for medical purposes provides a basis for their potential activity against various diseases. The introduction of herbal agents may lead to the development of new drug candidates with convincing activity. Rumex acetosella L. has been traditionally used for the antidiabetic purposes. The research pointed out various extracts and phytochemical constituents from R. acetosella may act as antihyperglycemic agents. Particularly, alcohol-including extracts of R. acetosella may be considered as promising alternatives in the prevention or treatment of type II DM. The study puts emphasis on the therapeutic value of the plants for antidiabetic medication.

Chemical and instrumental studies revealed that SLWPP-3 with a molecular mass of 3.5 kDa was composed of rhamnose, glucose, arabinose, galactose and uronic acid with a weight ratio of 1: 1: 4: 6: 15, and primarily contained →3,6)-β-d-Galp-(1→, →4)-α-GalpA-(1→(OMe), →4)-α-GalpA-(1→, →2,4)-α-d-Rhap-(1→, →3)-β-d-Galp-(1→, →4)-α-d-Glcp, and →4)-β-d-Galp residues in the backbone. The branch chain passes were connected to the main chain through the O-4 atom of glucose and O-3 atom of arabinose. Physiologically, the ability of SLWPP-3 to inhibit carbohydrate-digesting enzymes and DPPH and ABTS radicals, as well as protect pancreatic β cells from oxidative damage by decreasing MDA levels and increasing SOD activities, was confirmed. The findings elucidated the structural types of pumpkin polysaccharides and revealed a potential adjuvant natural product with hypoglycemic effects.
