Abstract
Fatty liver disease (FLD), which includes both non-alcoholic fatty liver disease (NAFLD) and alcoholic fatty liver disease (ALD), is a worldwide health concern. The etiology of ALD is long-term alcohol consumption, while NAFLD is defined as an abnormal amount of lipid present in liver cells, which is not caused by alcohol intake and has recently been identified as a hepatic manifestation of metabolic syndrome (such as type 2 diabetes, obesity, hypertension, and obesity). Inflammation, oxidative stress, and lipid metabolic dysregulation are all known to play a role in FLD progression. Alternative and natural therapies are desperately needed to treat this disease since existing pharmaceuticals are mostly ineffective. The aldose reductase (AR)/polyol pathway has recently been shown to play a role in developing FLD by contributing to inflammation, oxidative stress, apoptosis, and fat accumulation. Herein, we review the effects of plantderived compounds capable of inhibiting AR in FLD models. Natural AR inhibitors have been found to improve FLD in part by suppressing inflammation, oxidative stress, and steatosis via the regulation of several critical pathways, including the peroxisome proliferator-activated receptor (PPAR) pathway, cytochrome P450 2E1 (CYP2E1) pathway, AMP-activated protein kinase (AMPK) pathway, etc. This review revealed that natural compounds with AR inhibitory effects are a promising class of therapeutic agents for FLD.

Abstract
Chrysanthemum originates in China and has been cultivated for tea and food utilizations over 2 thousand years. According to differences in origin and processing methods, Chrysanthemum morifolium Ramat. can be categorized into many cultivars. This study aims to investigate the chemical components of chrysanthemum and clarify the similarities and differences between different chrysanthemum varieties. A total of 55 non-volatile components and 66 volatile components in chrysanthemum were identified by ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS/MS) and gas chromatography-mass spectrometry (GC-MS) methods, respectively. A rapid UPLC-MS/MS method was developed and validated for the simultaneous determination of 13 active components in 30 batches chrysanthemum samples of ten different cultivars. Multivariate statistical techniques were applied to analyze the samples. The result indicated that Boju, Huaiju and Chuju were more similar in terms of the ingredient content and Qiju, Jinsihuangju, Huangju, Hangju, Gongju, Fubaiju, Baiju have a high degree of similarity. Furthermore, isochlorogenic acid C, luteolin, apigenin-7-glucoside, chlorogenic acid, apigenin and cryptochlorogenic acid plays an important role in distinguishing different varieties of chrysanthemum. The established strategy explains the similarities and differences between different varieties of chrysanthemums to some extent, and provides certain reference value for the choice of chrysanthemums for eating or medicinal purposes in daily life.

Abstract
Phenolic compounds, widespread in plants, are a necessary part of the human regimen due to their antioxidant and pro-oxidative properties. Naturally, phenolics structurally range from a very simple phenolic molecule moiety to an intricate polymer. For decades, phenolic compounds have gained pronounced attention because of their protective effects against degenerative disorders such as inflammation, diabetes and cancer. Physico-chemical properties (eg, solubility) restricted their bioactivity and also limited their usage as nutraceutical ingredients. However, encapsulation technology like liposomal formulations has been developed for the delivery of phenolic compounds without affecting their original aesthetic and organoleptic property. Hence, this review outlines the antioxidant and pro-oxidative properties of phenolic compounds and focuses on biological activity reports of flavonoids and phenolic acids as antidiabetic, anti-inflammatory and anticancer agents. Also, the delivery applications of phenolic compounds as liposomes are discussed with few examples.

Abstract
Aldose reductase (AR) has been reported to be involved in the development of nonalcoholic fatty liver disease (NAFLD). Hepatic AR is induced under hyperglycemia condition and converts excess glucose to lipogenic fructose, which contributes in part to the accumulation of fat in the liver cells of diabetes rodents. In addition, the hyperglycemia-induced AR or nutrition-induced AR causes suppression of the transcriptional activity of peroxisome proliferator-activated receptor (PPAR) α and reduced lipolysis in the liver, which also contribute to the development of NAFLD. Moreover, AR induction in non-alcoholic steatohepatitis (NASH) may aggravate oxidative stress and the expression of inflammatory cytokines in the liver. Here, we summarize the knowledge on AR inhibitors of plant origin and review the effect of some plant-derived AR inhibitors on NAFLD/NASH in rodents. Natural AR inhibitors may improve NAFLD at least in part through attenuating oxidative stress and inflammatory cytokine expression. Some of the natural AR inhibitors have been reported to attenuate hepatic steatosis through the regulation of PPARα-mediated fatty acid oxidation. In this review, we propose that the natural AR inhibitors are potential therapeutic agents for NAFLD.

[PMID: 32048962 DOI: 10.2174/1381612826666200212115826] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2019] [Accepted: 12/05/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND For a long time, the researchers have been looking for new efficient methods to enhance production and obtain valuable plant secondary metabolites, which would contribute to the protection of the natural environment through the preservation of various plant species, often rare and endangered. These possibilities offer plant in vitro cultures which can be performed under strictly-controlled conditions, regardless of the season or climate and environmental factors. Biotechnological methods are promising strategies for obtaining the valuable plant secondary metabolites with various classes of chemical compounds including caffeoylquinic acids (CQAs) and their derivatives. CQAs have been found in many plant species which are components in the daily diet and exhibit a wide spectrum of biological activities, including antioxidant, immunomodulatory, antihypertensive, analgesic, anti-inflammatory, hepato- and neuroprotective, anti-hyperglycemic, anticancer, antiviral and antimicrobial activities. They have also been found to offer protection against Alzheimer's disease, and play a role in weight reduction and lipid metabolism control, as well as modulating the activity of glucose-6-phosphatase involved in glucose metabolism. METHODS This work presents the review of the recent advances in use in vitro cultures of various plant species for the alternative system to the production of CQAs and their derivatives. Production of the secondary metabolites in in vitro culture is usually performed with cell suspension or organ cultures, such as shoots and adventitious or transformed roots. To achieve high production of valuable secondary metabolites in in vitro cultures, the optimization of the culture condition is necessary with respect to both biomass accumulation and metabolite content. The optimization of the culture conditions can be achieved by choosing the type of medium, growth regulators or growth conditions, selection of high-productivity lines or culture period, supplementation of the culture medium with precursors or elicitor treatments. Cultivation for large-scale in bioreactors and genetic engineering: Agrobacterium rhizogenes transformation and expression improvement of transcriptional factor or genes involved in the secondary metabolite production pathway are also efficient strategies for enhancement of the valuable secondary metabolites. RESULTS Many studies have been reported to obtain highly productive plant in vitro cultures with respect to CQAs. Among these valuable secondary metabolites, the most abundant compound accumulated in in vitro cultures was 5-CQA (chlorogenic acid). Highly productive cultures with respect to this phenolic acid were Leonurus sibiricus AtPAP1 transgenic roots, Lonicera macranthoides and Eucomia ulmoides cell suspension cultures which accumulated above 20 mg g-1 DW 5-CQA. It is known that di- and triCQAs are less common in plants than monoCQAs, but it was also possible to obtain them by biotechnological methods. CONCLUSION The results indicate that the various in vitro cultures of different plant species can be a profitable approach for the production of CQAs. In particular, an efficient production of these valuable compounds is possible by Lonicera macranthoides and Eucomia ulmoides cell suspension cultures, Leonurus sibiricus transformed roots and AtPAP1 transgenic roots, Echinacea angustifolia adventitious shoots, Rhaponticum carthamoides transformed plants, Lavandula viridis shoots, Sausera involucrata cell suspension and Cichorium intybus transformed roots.

Abstract
Alcoholic liver disease (ALD) is caused by heavy alcohol consumption over a long period. Acetaldehyde-mediated toxicity, oxidative stress, and imbalance of lipid metabolism are generally considered involved in the initiation of ALD. There is an increasing requirement for alternative and natural medicine to treat ALD. Recently, aldose reductase (AR) has been reported to be involved in the development of ALD by affecting inflammatory cytokines, oxidative stress, and lipid metabolism. Here, we review the effect of plant-derived AR inhibitors on ALD in rodents. And we conclude that AR inhibitors of plant origin may enhance antioxidant capacity, inhibit lipid peroxidation and inflammatory cytokines expression, and activate AMP-activated protein kinase thereby subsequently suppressing alcohol-induced lipid synthesis in liver to achieve ALD protection. This review reveals that natural AR inhibitor may be potential therapeutic agent for ALD.

Abstract
Hepatocellular carcinoma (HCC) is the most common liver cancer and is known to be resistant to conventional chemotherapy. The use of herbal medicine and supplements has increased over recent decades following side effects and resistant to conventional chemotherapy. The seeds of Bixa orellana L. commonly known as annatto have recently gained scientific attention due to presence of a carotenoid bixin for its substantial anticancer properties. However, molecular mechanisms underlying bixin-induced apoptosis are still unclear. Treatment of bixin significantly decreased the number of Hep3B cells and morphological study revealed the change in cellular and nuclear morphology that trigger the events of apoptosis confirmed by annexin V/PI staining. Further DCFDA and rhodamine 123 spectrofluorimetry study showed elevation in reactive oxygen species (ROS) production and loss of mitochondrial membrane potential (MMP), respectively. ROS production caused DNA damage and apoptosis was marked by cell cycle arrest, up-regulation of Bax and FasL protein as well as cleavage of caspase-9, caspase-8 and caspase-3 protein. Docking study with pro-apoptotic molecule Bax and surface Fas ligand exhibited energetically favourable binding interaction. Collectively, these results suggest that bixin capable of modulating the extrinsic and intrinsic molecules of apoptosis indicating its potential for development of promising candidate for hepatocellular carcinoma.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The prevalence of diabetes is on a steady increase worldwide and it is now identified as one of the main threats to human health in the 21st century. In Nigeria, the use of herbal medicine alone or alongside prescription drugs for its management is quite common. We hereby carry out a review of medicinal plants traditionally used for diabetes management in Nigeria. Based on the available evidence on the species׳ pharmacology and safety, we highlight ways in which their therapeutic potential can be properly harnessed for possible integration into the country׳s healthcare system. MATERIALS AND METHODS Ethnobotanical information was obtained from a literature search of electronic databases such as Google Scholar, Pubmed and Scopus up to 2013 for publications on medicinal plants used in diabetes management, in which the place of use and/or sample collection was identified as Nigeria. 'Diabetes' and 'Nigeria' were used as keywords for the primary searches; and then 'Plant name - accepted or synonyms', 'Constituents', 'Drug interaction' and/or 'Toxicity' for the secondary searches. RESULTS The hypoglycemic effect of over a hundred out of the 115 plants reviewed in this paper is backed by preclinical experimental evidence, either in vivo or in vitro. One-third of the plants have been studied for their mechanism of action, while isolation of the bioactive constituent(s) has been accomplished for twenty three plants. Some plants showed specific organ toxicity, mostly nephrotoxic or hepatotoxic, with direct effects on the levels of some liver function enzymes. Twenty eight plants have been identified as in vitro modulators of P-glycoprotein and/or one or more of the cytochrome P450 enzymes, while eleven plants altered the levels of phase 2 metabolic enzymes, chiefly glutathione, with the potential to alter the pharmacokinetics of co-administered drugs. CONCLUSION This review, therefore, provides a useful resource to enable a thorough assessment of the profile of plants used in diabetes management so as to ensure a more rational use. By anticipating potential toxicities or possible herb-drug interactions, significant risks which would otherwise represent a burden on the country׳s healthcare system can be avoided.

Abstract
The Brazilian flora was widely used as source of food and natural remedies to treat various diseases.Bixa orellanaL. (Bixaceae), also known as annatto, urucù, or achiote, is a symbol for the Amazonian tribes that traditionally use its seeds as coloured ink to paint their bodies for religious ceremonies. The aim of this study was to investigate the volatile organic compounds (VOCs) profile ofB. orellanafresh fruits (in vivosampled), dried seeds, wood, bark, and leaves analyzed with Headspace solid-phase microextraction coupled with gas chromatography and mass spectrometry. A screening on phenolic content (the Folin-Ciocalteu assay) and antiradical activity (DPPH assay) of seeds was also conducted. In addition, the repellent properties of seed extracts againstAedes aegyptiL. were investigated. Volatile compounds detected inB. orellanasamples consisted mainly of sesquiterpenes, monoterpenes, and arenes:α-humulene is the major volatile compound present in seed extracts followed by D-germacrene,γ-elemene, and caryophyllene.B. orellanaproved to be a good source of antioxidants. Preliminary data on repellency againstA. aegyptiof three different dried seed extracts (hexane, ethanol, and ethanol/water) indicated a significant skin protection activity.

Abstract
A multicomponent quantification fingerprint based on HPLC coupled with diode array detection and electrospray ionization tandem mass spectrometry (HPLC-DAD-ESI/MS) technique has been established for the analysis of phenolic compounds in 12 samples originated from 5 different cultivars of Chrysanthemum morifolium flowers in China. Four caffeoylquinic acids and 15 flavonoids in the capitulum were identified by comparing the retention times and ultraviolet spectra as well as the mass spectrum and/or matching the empirical molecular formula with that of reference compounds, and the contents of these compounds have been determined simultaneously. The samples from three medicinal cultivars significantly differed in the quality and quantity of flavonoid aglycones and glycosides compared with those from two edible cultivars, which allows the possibility of showing the chemical distinctness of these cultivars and may be useful in their standardization. Moreover, the antiallergic effects of these cultivars were comparatively assayed for the first time. A representative medicinal cultivar, 'huaiju', showed potential activity on the inhibition of antigen-induced degranulation from RBL-2H3 cells and compound 48/80-induced scratching in mice, whereas the in vitro and in vivo antiallergic activities of two edible cultivars were weak. The results suggested that the quality and quantity of some active flavonoid aglycones should be responsible for the pharmacological profiles of these cultivars.

Abstract
AIM OF STUDY The ethnobotanical study surveyed the different types of medicinal plants used for the treatment of malaria in the south-western region of Nigeria. MATERIALS AND METHODS Information was collected by interviewing indigenous people, using a semi-structured questionnaire. Collected plant samples were identified and authenticated in Forestry Research Institute of Nigeria, Ibadan, Nigeria. RESULTS A total of 151 respondents were interviewed of which 64% were females and 36% males. This population comprised of herbal medicine sellers (39%), traditional doctors (15%), housewives (24%) and farmers (22%). Twenty two plants species used in the treatment of malaria belonging to 18 families were identified and compiled detailing information such as common and vernacular names, parts used, methods of preparation and previous scientific reports. Of the plants identified during the survey, Azadirachta indica (12.9%), Alstonia congensis (11.9%) and Cymbopogon citratus (11.3%) showed the highest incidence of encounter whereas Nauclea latifolia recorded the lowest incidence of encounter (0.2%). The traditional usage of Persea americana and Ludwigia peruviana in the treatment of malaria is reported here for the first time. CONCLUSION Though a large number of traditionally used plants for the treatment of malaria were identified, scientific validation of the traditional claims of anti-malarial properties is imperative. This would establish their candidature for any possible future research for active principles and the possible development of new cheaper and more effective anti-malarial drugs, as well as in the conservation of this rich diversity of anti-malarial plants.

Abstract
Five polar constituents of Origanum vulgare L. ssp. hirtum were investigated for their ability to inhibit aldose reductase (ALR2), the first enzyme of the polyol pathway implicated in the secondary complications of diabetes. The most active compound was found to be lithospermic acid B. Caffeic acid was inactive as it showed no inhibitory activity against the enzyme. The order of the inhibitory activity of the remaining compounds was: rosmarinic acid >12-hydroxyjasmonic acid 12-O-beta-glucopyranoside > p-menth-3-ene-1,2-diol 1-O-beta-glucopyranoside. Docking studies have been undertaken to gain insight into the binding mode of the investigated compounds at the active site of ALR2. The predicted hydrogen bonding and hydrophobic interactions may explain the observed inhibitory activity.

Abstract
Caesalpinia ferrea MART. (Leguminosae) called as Juca is one of the medicinal plants in Brazil used for diabetes. From the fruits of this plant, ellagic acid (EA) and 2-(2,3,6-trihydroxy-4-carboxyphenyl)ellagic acid (TEA) have been recently isolated as aldose reductase (AR) inhibitors. In this study, we examined to prove the inhibitory activity against AR of EA and TEA in vitro, and EA in vivo by measurement of the accumulation of sorbitol, which is the product of glucose reduction catalyzed by AR. TEA was not examined in vivo because of its shortage of yield from the fruits. EA and TEA significantly and dose-dependently inhibited sorbitol accumulation in erythrocytes, lens and sciatic nerve under incubating with glucose in vitro. EA at a dose of 75 mg/kg/d showed the most potent inhibition of sorbitol accumulation in erythrocytes, lens and sciatic nerve at 50, 75 and 100 mg/kg/d in vivo. These results suggest that the inhibitory activity of EA against AR causes to inhibit sorbitol accumulation by in vitro and in vivo experiments. EA is distributed in fruits and vegetables, so that taking them might be able to relieve diabetic complications.

Abstract
Annatto preparations based on extracts of the seed of tropical bush Bixa orellana L consist of carotenoid-type pigments. Previous reports indicate that commercial annatto extracts have biological activities against microorganisms of significance to food fermentation, preservation, and safety. The objective of this study was to separate and identify the compound(s) responsible for the antimicrobial activity of annatto preparations. Commercial water-soluble annatto extracts were screened by thin-layer chromatography and bioautography followed by liquid chromatography/photodiode array/mass spectrometry (LC/PDA/MS) analysis of active fractions. Bioautography revealed two fractions with antimicrobial activity against Staphylococcus aureus. LC/PDA/MS analysis of both fractions revealed 9'-cis-norbixin (UV(max) 460 and 489 nm) and all-trans-norbixin (UV(max) 287, 470, and 494 nm) as the major components. Structure confirmation was achieved by (1)H NMR spectroscopy. Results indicate that 9'-cis-norbixin and all-trans-norbixin are responsible for the antimicrobial properties of annatto.

Abstract
A crude extract prepared from roots of Mallotus resinosus exhibited significant Cu(2+)-dependent DNA strand scission activity and was thus selected for bioassay-guided fractionation. Scopoletin (1), a simple coumarin, was identified as the active principle responsible for DNA cleavage activity of the crude extract. The DNA strand scission activity of 1, as well as that of three structural analogues, is reported.

Abstract
Annatto preparations are used to impart distinctive flavor and color to foods and are a primary colorant in dairy foods such as cheese and butter. There are several reports indicating that certain fractions of the annatto plant have biological activities against microorganisms of significance in food fermentation, food preservation, and human health. However, little is reported describing the nature of the antimicrobial compound(s) or their potential presence in commercial annatto colorant preparations. This study was conducted to determine whether commonly available annatto extracts are capable of influencing the outgrowth of selected lactic acid, spoilage, and pathogenic microorganisms. Disk diffusion and tube macrodilution techniques were used to determine the MICs and MBCs of double-strength water-soluble annatto extracts. Standard antibiotic disks were used as controls for the disk diffusion assay. The results demonstrate that annatto has an inhibitory effect on Bacillus cereus, Clostridium perfringens, and Staphylococcus aureus, with MICs of 0.08, 0.31, and 0.16% (vol/vol) and diameters of inhibition of 9 to 10, 12 to 13, and 15 to 16 mm, respectively. A concentration of 0.63% (vol/vol) inhibited the growth of Streptococcus thermophilus, Lactobacillus casei subsp. casei, Lactococcus lactis, and Paenibacillus polymyxa. The MICs for Listeria monocytogenes and Enterococcus durans were 1.25 and 2.5% (vol/vol), respectively. No activity was detected against Lactobacillus plantarum, Bifidobacterium bifidum, yeasts, or selected gram-negative bacteria.
