Abstract
OBJECTIVE Present study was to observe the therapeutic aspects of seed cake extracts of Ocimum sanctum against the oral cancer cell line with the activation of p53 apoptotic pathway. METHOD Seed cake extracts were characterized using GC-MS analysis. Cytotoxic activity was observed on KB cells and L929 cell through MTT assay and scratch assay. Antioxidant activity on KB cells were determined using enzymatic and non enzyme content in the treated cells. Chick chorioallantoic membrane (CAM) was established to check the presence of blood vessel formation and neuvasculature pattern in the treated fertilized eggs. DNA fragmentation and gene expression studies were also determined in the treated cells to check the upregulation of apoptotic pathways. RESULTS GC-MS analysis confirmed alkaloids, phenols, and many. The cytotoxic activity showed maximum antiproliferative potential with aqueous extract, whereas no cytotoxic effect was observed on L929 cells. The ethanolic and aqueous extract has shown a greater SI value. Scratch assay has signified that aqueous extract has a lower migration rate of KB cells. Aqueous extract showed maximum enzymatic activity and lower malondialdehyde content in cells treated with ethanolic extract. CAM model confirmed that eggs treated with aqueous extract has shown inhibition of vasculature pattern and dissolutions of blood vessels. DNA Fragmentation and Gene expression studies confirmed maximum fold in the KB cell treated with an aqueous extract of seed cake leading to activation of p53 dependent apoptotic pathway. CONCLUSION The potent therapeutic properties of seed cake extracts have been proven, and they can be used as herbal treatments to prevent oral cancer.

Abstract
Abrus precatorius L. is a traditional remedy with a long history of use in medicine around the globe due to its diverse phytochemical composition and bioactivities which are of utmost significance to the scientific community. With the aim to provide new insights into the antioxidant, antiproliferative and antiangiogenic properties of A. precatorius aqueous seed extracts, different extraction methods were employed. Aqueous extract prepared by Soxhlet method APW (Sox) had higher total phenolics, flavonoids and tannin content. In DPPH assay, APW (Sox) had the maximum free radical scavenging activity. The maximum FRAP value was displayed by APW (Mac). The maximum inhibition was shown by APW (Sox) against HPV18 (Hep2C) cells and APW (Mac) against HPV18 (KB) cells. In cervical cancer (Hep2C) cells, catalase (CAT), glutathione-s-transferase (GST) activity, and glutathione (GSH) content were all highest in APW (Sox) extract, whereas APW (Mac) extract demonstrated the highest superoxide dismutase (SOD) activity and the lowest malondialdehyde (MDA) content. Similarly, in oral cancer (KB) cells, APW (Mac) extract showed the highest SOD, CAT, GST activity and GSH content whereas APW (Sox) extract showed the least MDA content. Docking studies showed that tannic acid and rutin had the highest binding affinity, while MD simulations showed that they were stable in complex with COX-2 for at least 90 ns. Promising antiangiogenic activities were observed in both APW (Sox) and APW (Mac) in a dose dependent manner. Therefore, aqueous seed extracts of A. precatorius could be considered promising candidates for anticancer and antiangiogenic drugs.Communicated by Ramaswamy H. Sarma.

Abstract
Abrus precatorius is a poisonous plant known since ancient times. Accidental poisoning is more common due to the intake of plant seeds containing deadly abrin which is a highly toxic and a thermolabile plant toxalbumin. Abrin has also been reported to be a potential chemical agent that can be used as bioweapon in military or terrorism. Abrin is a ribosome inactivating protein that contains multiple isotoxic forms of protein subunits called chain A and B. The identification of this toxalbumin in the plant is important to determine cause of death in poisoning cases. Therefore, the present review focuses on the structure, mode of administration, tokicokinetics, extraction procedures and forensic analysis of abrin and other constituents. It is observed that most of the researchers have utilized immunological methods for the detection of plant components. This technique has proved to be more sensitive, reliable and accurate for the detection of extremely low concentrations of toxin.

Abstract
Abrus precatorius is a tropical medicinal plant with multiple medicinal benefits whose seeds have not yet been studied against cervical cancer. Herein, we have assessed the antioxidant and antiproliferative properties of seed extracts (ethyl acetate and 70% ethanol) prepared from Soxhlet and Maceration extraction methods against Hep2C and HeLa Cells. We observed that the APE (Sox) extract had a significantly higher total flavonoid content, APA (Mac) extract had a high total phenolic content, and APA (Sox) extract had a high total tannin content. Further, HPLC analysis of extracts revealed the presence of tannic acid and rutin. Moreover, APA (Sox) exhibited the highest free radical scavenging activity. APE (Mac) had the best antiproliferative activity against Hep2C cells, while APA (Sox) had the best antiproliferative activity against HeLa cells. In Hep2C cells, APE (Mac) extract revealed the highest SOD, catalase activity, GSH content, and the lowest MDA content, whereas APA (Mac) extract demonstrated the highest GST activity. In HeLa cells, APA (Sox) extract showed the highest SOD, GST activity, GSH content, and the least MDA content, whereas APA (Mac) extract showed the highest catalase activity. Lastly, docking results suggested maximum binding affinity of tannic acid with HER2 and GCR receptors. This study provides evidence that A. precatorius seed extracts possess promising bioactive compounds with probable anticancer and antioxidant properties against cervical cancer for restricting tumor growth.

Abstract
Schedule E1 is an important part of Drugs and Cosmetics Act (Government of India) that comprises the list of poisonous drugs from plant, animal and mineral origins to be consumed under medical supervision. Ayurveda, the world's oldest medicinal system has a list of drugs represented in schedule E1 that are used since thousands of years. This review reports the anti-cancer activities of fifteen toxic ayurvedic drugs from plant origin represented in Drugs and Cosmetics Act, 1940. The information was collected from the various authentic sources, compiled and summarised. The plant extracts, formulations, phytoconstituents and other preparations of these drugs have shown effective activities against mammary carcinoma, neuroblastoma, non-small cell lung carcinoma, lymphocytic leukaemia, colorectal adenocarcinoma, Ehrlich ascites carcinoma, prostate adenocarcinoma, glioblastoma asterocytoma and other malignancies. They have various mechanisms of action including Bax upregulation, Bcl2 downregulation, induction of cell cycle arrest at S phase, G2/M phase, inhibition of vascular endothelial growth factors, inhibition of Akt/mTOR signalling etc. Certain traditional ayurvedic preparations containing these plants are reported beneficial and the possibilities of these drugs as the alternative and adjuvant therapeutic agents in the current cancer care have been discussed. The studies suggest that these drugs could be utilised in future for the critical care of malignancies.

Abstract
Abrus precatorius is considered to be a valuable source of natural products for the development of drugs against various diseases. Herein, the genome size and phytochemical compounds in the leaves and callus of A. precatorius were evaluated. The endangered A. precatorius was collected from the Al-Baha mountains, Saudi Arabia and identified based on the phylogenetic analysis of a DNA sequence amplified by ITS1 and ITS4 primers. The callus was induced by the culture of stem explants onto Murashige and Skoog medium (MS) supplemented with various combinations of 2,4-dichlorophenoxyacetic acid (2,4D) and 6-Benzylaminopurine (BAP). The callus with the highest fresh weight (2.03 g) was obtained in the medium containing 0.5µM BA and 5 µM 2,4-D after 8 weeks of culture; thus, the callus of this combination was selected for the genome estimation and phytochemical compound extraction. The genetic stability of the leaves from the donor as well as in the regenerated callus was analyzed by flow cytometry with optimized tomato (2C = 1.96 pg) as an external reference standard. The 2C DNA content was estimated to 1.810 pg ± 0.008 and 1.813 pg ± 0.004 for the leaves and callus, respectively. Then, the total phenol and total flavonoid contents in the methanol extract of the callus and leaves were measured using a spectrophotometer and the High-performance liquid chromatography (HPLC ) methods. The results showed that the methanolic extract of the leaves was higher in total phenols and total flavonoids than the callus extract. Finally, the extracts of callus and leaves were analyzed for phytochemical compound through the Gas chromatography and Mass spectroscopy (GC-MS). A total of 22 and 28 compounds were detected in the callus and leaves, respectively. The comparative analysis showed that 12 compounds of the secondary metabolites were present in both extracts.

In-vitro cytotoxicity in relation to chemotypic diversity in diploid and tetraploid populations of Gentiana kurroo Royle. JOURNAL OF ETHNOPHARMACOLOGY 2021; 274:113966. [PMID: 33647427 DOI: 10.1016/j.jep.2021.113966] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Revised: 11/27/2020] [Accepted: 02/22/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Gentiana kurroo is a multipurpose critically endangered medicinal herb prescribed as medicine in Ayurveda in India and exhibits various pharmacological properties including anti-cancer activity. The species is rich repository of pharmacologically active secondary metabolites together with secoiridoidal glycosides. AIM OF THE STUDY The study aimed to investigate the chemical diversity in different populations/cytotypes prevailing in G. kurroo to identify elite genetic stocks in terms of optimum accumulation/biosynthesis of desired metabolites and having higher in-vitro cytotoxicity potential in relation to chemotypic diversity. MATERIAL AND METHODS The wild plants of the species were collected from different ranges of altitudes from the Kashmir Himalayas. For cytological evaluation, the standard meiotic analysis was performed. The standard LC-MS/MS technique was employed for phytochemical analysis based on different marker compounds viz. sweroside, swertiamarin, and gentiopicroside. Different tissues such as root-stock, aerial parts, and flowers were used for chemo-profiling. Further, the methanolic extracts of diploid and tetraploid cytotypes were assessed for cytotoxic activity by using MTT assay against four different human cancer cell lines. RESULTS The quantification of major bioactive compounds based on tissue- and location-specific comparison, as well as in-vitro cytotoxic potential among extant cytotypes, was evaluated. The comprehensive cytomorphological studies of the populations from NW Himalayas revealed the occurrence of different chromosomal races viz. n = 13, 26. The tetraploid cytotype was hitherto unreported. The tissue-specific chemo-profiling revealed relative dominance of different phytoconstituents in root-stock. There was a noticeable increase in the quantity of the analyzed compounds in relation to increasing ploidy status along the increasing altitudes. The MTT assay of methanolic extracts of diploid and tetraploid cytotypes displayed significant cytotoxicity potential in tetraploids. The root-stock extracts of tetraploids were highly active extracts with IC50 value ranges from 5.65 to 8.53 μg/mL against HCT-116 colon cancer. CONCLUSION The chemical evaluation of major bioactive compounds in diverse cytotypes from different plant parts along different altitudes presented an appreciable variability in sweroside, swertiamarin, and gentiopicroside contents. Additionally, the concentrations of these phytoconstituents varied for cytotoxicity potential among different screened cytotypes. This quantitative difference of active bio-constituents was in correspondence with the growth inhibition percentage of different tested cancer cell lines. Thus, the present investigation strongly alludes towards a prognostic approach for the identification of elite cytotypes/chemotypes with significant pharmacological potential.

[PMID: 32682384 DOI: 10.2174/1871520620666200719000449] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 06/09/2020] [Accepted: 06/25/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND The use of medicinal plants for general wellbeing and disease treatment is a common practice among tribal communities of Kokrajhar districts of Assam. However, little works have been done to study the pharmacological aspect of the plants. OBJECTIVES The present study intends to study the antioxidant and antiproliferative properties of selected medicinal plants used by the tribal communities of the Kokrajhar district of Assam since ancient times. METHODS Five traditionally important medicinal plants, namely, Cassia fistula, Citrus grandis, Lindernia crustacea, Sacciolepis myosuroides, and Zingiber zerumbet were investigated for antioxidant, antiproliferative (cytotoxic) and apoptosis-inducing potential in the malignant cancer cell line. Phytochemical content, such as phenolic and flavonoid content, were estimated following standard protocol. The methanolic extract of plants was investigated following the phosphomolybdate method (TAC), FRAP, DPPH, ABTS, and TBARS assays. Antiproliferative activities of the plants were carried out by MTT assay in DL and PBMC cells. The apoptotic study was carried out following the acridine orange and ethidium bromide staining method and fluorescent microscopic imaging. Based on the significant (P≤0.05) high apoptotic inducing potential of the plant and to further dissect the molecular mode of action, including downstream biological action, major phytochemicals derived from L. crustacea were investigated for its prospective binding affinity with anti-apoptotic cancer target proteins. RESULTS Antioxidant studies by FRAP, DPPH, ABTS, and TBARS assay revealed that all five plants contain considerable free radical scavenging activity. C. fistula showed the strongest free radical scavenging activity while the fruit peel extract of C. grandis showed poor activity. The overall antioxidant activities of plants such as TAC, FRAP, DPPH, ABTS, and TBARS may be arranged in decreasing activity as C. fistula > Z. zerumbet > L. crustacea > S. myosuroides > C. grandis. MTT based cell proliferation study showed that all the plants extract significantly (P≤0.05) inhibited cell viability with negligible cytotoxicity (~5-12%) in normal cells. Moreover, L. crustacea showed promising antiproliferative and apoptosis-inducing ability against Dalton's lymphoma. It is worth mentioning that the major bioactive compounds of the most potent plant extract, L. crustacea interacted with anti-apoptotic proteins (cancer target) with higher affinity and the results are compared with reference inhibitors. CONCLUSION It is worth noting that these plants have the potential to consider for further scientific studies in different cell lines and animal models. Furthermore, isolation and characterization of bioactive compound(s) may promise the discovery of new and valuable drugs candidate to tackle various human diseases.

Abstract
Complexes of 4-(((2-aminopyridin-3-yl)methylene)amino)benzoic acid ligand with cobalt(II) (1), nickel(II) (2), copper(II) (3), zinc(II) (4) and palladium(II) (5) are synthesized and characterized by using different spectroscopic methods like, UV-Visible, infrared, 1H, 13C NMR, molar conductance, ESR and elemental analysis. Quantum chemical computations were made using DFT (density functional theory), B3LYP functional and 6-31+ +G(d,p)/SDD basis set in order to determine optimized structure parameters, frontier molecular orbital parameters and NLO properties. Based on DFT and experimental evidence, the complexes ensured that the octahedral geometry have been proposed for complexes 1, 2 and 4, square planar for complexes 3 and 5. All the complexes showed only residual molar conductance values and hence they were considered as non-electrolytes in DMF. In addition, the anti-proliferative activity of the compounds was evaluated against different human cancer cell lines (IMR-32, MCF-7, COLO205, A549, HeLa and HEK 293) and cisplatin is used as a reference drug. Compounds 1 and 4 showed remarkable cytotoxicity in five cancer cell lines tested except MCF-7. Also, the compounds were examined for their in vitro antimicrobial and scavenging activities. The molecular docking results are well corroborated with the experimental anticancer activity results.

Abstract
Artemisia and its allied species have been employed for conventional medicine in the Northern temperate regions of North America, Europe, and Asia for the treatments of digestive problems, morning sickness, irregular menstrual cycle, typhoid, epilepsy, renal problems, bronchitis malaria, etc. The multidisciplinary use of artemisia species has various other health benefits that are related to its traditional and modern pharmaceutical perspectives. The main objective of this review is to evaluate the traditional, modern, biological as well as pharmacological use of the essential oil and herbal extracts of Artemisia nilagirica, Artemisia parviflora, and other allied species of Artemisia. It also discusses the botanical circulation and its phytochemical constituents viz disaccharides, polysaccharides, glycosides, saponins, terpenoids, flavonoids, and carotenoids. The plants have different biological importance like antiparasitic, antimalarial, antihyperlipidemic, antiasthmatic, antiepileptic, antitubercular, antihypertensive, antidiabetic, anxiolytic, antiemetic, antidepressant, anticancer, hepatoprotective, gastroprotective, insecticidal, antiviral activities, and also against COVID-19. Toxicological studies showed that the plants at a low dose and short duration are non or low-toxic. In contrast, a high dose at 3 g/kg and for a longer duration can cause toxicity like rapid respiration, neurotoxicity, reproductive toxicity, etc. However, further in-depth studies are needed to determine the medicinal uses, clinical efficacy and safety are crucial next steps.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Abrus precatorius (L.) leaves are used as folk medicine by the local communities in the western region of Ghana to treat diabetes mellitus; however, this health claim remains unverified scientifically. OBJECTIVE The study investigated glucose lowering and pancreato-protective effects of Abrus precatorius leaf extract (APLE) in normoglycemic and STZ/nicotinamide (NIC)-induced diabetic rats. METHOD after preparation of APLE, it was subjected to phytochemical screening, proximate composition and elemental assessments by using standard methods. Oral glucose tolerance test (OGTT) and maltose, lactose and sucrose oral challenge were assessed in normoglycemic rats post-APLE. Morphological characteristics of glucose response curve (time of glucose peak and shape of glucose response curve) were determined. Subsequently, diabetes mellitus was experimentally established in normoglycaemic adult Sprague-Dawley rats (weighing 150-250 g) of both sexes by sequential injection of Streptozotocin (STZ, 60 mg/kg ip)-reconstituted in sodium citrate buffer and NIC (110 mg/kg ip)-reconstituted in normal saline (1:1 v/v) for 16 weeks. Except control rats (normal saline 5 ml/kg ip; baseline fasting blood glucose [FBG] of 6.48 mmol/L), rats having FBG (stable at 11.1 mmol/L or ≥ 250 mg/dL) 3 days post-STZ/NIC injection were randomly re-assigned to one of the following groups: model (STZ/NIC-induced diabetic rats), APLE (100, 200 and 400 mg/kg respectively po) and metformin (300 mg/kg po) and treated daily for 28 days. Bodyweight and FBG were measured on weekly basis. FBG was measured by using standard glucometers. On day 28, rats were sacrificed under chloroform anesthesia, blood collected via cardiac puncture; kidney, liver and pancreas surgically harvested. While the pancreas was processed, sectioned and H&E-stained for histological examination, fresh kidney and liver were homogenized for assessment of total anti-oxidant capacity. Median cross-sectional area of pancreatic islets of Langerhans was determined for each group by using Amscope. RESULTS Cumulatively, APLE (100, 200 and 400 mg/kg respectively) dose-dependently decreased the initial FBG by 55.22, 76.15 and 77.77% respectively compared to model (-1.04%) and metformin (72.29%) groups. APLE treatment recovered damaged pancreatic β-cells and also increased median cross-sectional area (x106 μm2) of pancreatic islets compared to that of model group. APLE significantly (P < 0.05) increased total anti-oxidant capacity (5.21 ± 0.02 AscAE μg/mL) of plasma, kidney and liver compared to model (4.06 ± 0.04 AscAE μg/mL) and metformin (4.87 ± 0.03 AscAE μg/mL) groups. CONCLUSION APLE has demonstrated glucose lowering and pancreato-protective effects in rats and arrested the characteristic loss in bodyweight associated with diabetes mellitus. This finding preliminarily confirms folk use of APLE as an anti-diabetic herbal medicine, whiles providing a rationale for further translational studies on APLE.

Abstract
Hagenia abyssinica (Bruce) J. F. Gmel. is a multipurpose dioecious tree that has been used to treat various ailments, for example, the flowers of H. abyssinica have been widely used as a tea to treat intestinal parasites by local residents and the roots of H.abyssinica could also be used for anticancer purposes. Antioxidant activity could be one of the most important pathways to suppress cancer and there is hardly any information available on the specific chemical components corresponding to the bioactivities of H. abyssinica to date. The present study intended to screen and evaluate the antioxidant and anti-proliferative properties of five different fractions from H. abyssinica along with their corresponding total flavonoid and phenolic contents and then further identify those compounds with the most potent antioxidant and anti-proliferative activities using high performance liquid chromatography (HPLC) coupled to mass spectrometry (MS) and nuclear magnetic resonance (NMR). The total flavonoid and phenolic content assays showed that the ethyl acetate (EA) fraction of H. abyssinica had higher flavonoid and phenolic levels than the other four fractions. Furthermore, the 2,2-diphenyl-1-picrylhydrazyl (DPPH) superoxide radical scavenging abilities, total antioxidant capacity (TAC) assay with 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid (ABTS), and ferric-reducing antioxidant power (FRAP) were measured to evaluate the antioxidant activities of the five fractions and some pure compounds isolated from the EA fraction, which displayed higher antioxidant properties than that of the other fractions. Caffeic acid from the EA fraction showed even stronger DPPH scavenging ability (IC50 7.858 ± 0.31 µg/mL) than that of Vc (IC50 8.27 ± 0.11 µg/mL) as the positive control. The anti-proliferative properties of four fractions and the ethanol extract were evaluated by the 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide (MTT) assay and the EA fraction exhibited higher anti-proliferative activities against three cancer cell lines than that of the other fractions. Additionally, the compounds with good antioxidant activity from the EA fraction of H. abyssinica were screened and identified using LC-MS and NMR and were also found to possess good anti-proliferative activity. In the MTT assay, the quercetin showed the strongest dose-dependent anti-proliferative activities to colon cancer cells (HT-29) and liver cancer cells (HepG2) among all of the compounds isolated. This study provided valuable information on the synergistic antioxidant and anti-proliferative properties of H. abyssinica.

Abstract
Abstract
Background
Abrus precatorius possesses various therapeutic properties including anticancer potentials. This study evaluated the anti-proliferative activities of fractions of methanol root extract of A. precatorius on breast and cervical cancer cells and their immunomodulatory effect. Phytochemical screening was done by FTIR and GCMS. In vitro anti-proliferative effect was evaluated on human breast cancer (AU565) and cervical cancer (HeLa) cells and on murine fibroblast (NIH 3 T3) cells. Antioxidant activity was performed via DPPH radical scavenging assay. The immunomodulatory potential of fractions was evaluated by inhibition of phagocytes oxidative burst (ROS), Nitric oxide (NO) and proinflammatory cytokine TNF-α.
Results
A. precatorius fractions showed different chemical groups and were somewhat selective in antiproliferative activity against studied cancer cells. Ethyl acetate fraction showed the most significant antiproliferative activity with IC50 values of 18.10 μg/mL and 11.89 μg/mL against AU565 and HeLa cells respectively. Hexane fraction significantly (p < 0.05) inhibited HeLa cells (IC50 18.24 ± 0.16 μg/mL), whereas aqueous fraction showed mild inhibition (IC50 46.46 ± 0.14 μg/mL) on AU565 cell proliferation. All fractions showed no cytotoxicity against NIH-3 T3 murine fibroblast normal cells. All fractions showed potent and significant (p < 0.001) DPPH radical scavenging activity as well as suppressed phagocytic oxidative burst. Hexane (< 1 μg/mL), ethyl acetate (< 1 μg/mL), and butanol (5.74 μg/mL) fractions potently inhibited the cytokine TNF- α, hexane (< 1 μg/mL) and ethyl acetate (< 1 μg/mL) fractions also potently inhibited NO.
Conclusions
The antiproliferative activities and suppressive effect on the phagocytic oxidative burst, NO and proinflammatory cytokine might be due to the synergistic actions of bioactive compounds especially flavonoids present in the assayed fractions and therefore, suggest chemotherapeutic use of A. precatorius in cancer treatment.

Abstract
This study's aim was to determine the antioxidant and anticholinesterase activities of Gloeophyllum odoratum, Gloeophyllum sepiarium, and Gloeophyllum trabeum species with phenolic profiles. The major compound in G. odoratum (101.6 µg/g) and G. sepiarium (92.61 µg/g) mushrooms was fumaric acid, while ferulic acid was found as the main compound in G. trabeum (11.67 μg/g). The methanol extracts of Gloeophyllum species exhibited the highest activity in CUPRAC, DPPH• , β-carotene-linoleic acid, and ABTS•+ assays while the n-hexane extracts showed the highest activity in the metal chelating assay. Also, the methanol extract of G. odoratum (IC50 : 32.16 ± 0.28 µg/mL) was found to be highly active than its antioxidant standard α-tocopherol (IC50 : 38.51 ± 0.54 µg/mL) in the ABTS•+ radical scavenging assay. All the studied Gloeophyllum species extracts were found to be moderate inhibitors against AChE, whereas G. sepiarium n-hexane extract (69.70 ± 1.92%) and G. odoratum n-hexane extract (58.08 ± 1.36%) exhibited potent BChE inhibitory activity. PRACTICAL APPLICATIONS: The results of these studies demonstrated that the methanol and the n-hexane extracts had a potential application as alternative natural products for pharmaceutical, food, and cosmetic industries. In addition, the chemometric analysis by principal component analysis and hierarchical clustering analysis techniques could be used for the classification of the extracts of Gloeophyllum according to their bioactivity results. This is the first comprehensive study on phenolic profiles and bioactivities of G. odoratum, G. sepiarium, and G. trabeum mushroom species.

Abstract
Background The use of plants for the treatment and prevention of diseases in man and his animals has led to a renewed scientific interest in the use of medicinal plants for therapeutic purposes. The nephroprotective properties of methanol stem bark extract of Abrus precatorius against gentamicin-induced renal damage in rats was evaluated in this study. Methods Thirty male Wistar rats were divided into five equal groups. Group A was the negative control group while B was the positive control group which received gentamicin 100 mg/kg intra-peritoneally for 6 days. Group C were pretreated with 100 mg/kg extract for the 3 days and then concurrently with gentamicin 100 mg/kg for 3 days and group D were pretreated with 200 mg/kg extract for 3 days and then concurrently with gentamicin 100 mg/kg for 3 days. Group E received gentamicin intraperitoneally for 6 days followed by administration of 200 mg/kg of the extract for 3 days. Blood samples, kidneys and kidney homogenates were collected for haematological, biochemical, histopathological and immunohistochemical analysis. Results The results showed that no significant haematological changes were noted. The groups treated with extract exhibited significant increase in body weight gain. While group B significantly exhibited focal areas of inflammation, fatty degeneration, congestion of vessels, tubular necrosis and glomerular atrophy, the lesions were mild with the treated groups. Treated groups exhibited a dose dependent significant decrease in serum creatinine, urea, XO, NO and Myeloperoxidase, AOPP, Protein carbonyl, H2O2 generated and MDA levels when compared with group B. There were significant dose dependent improvements in SOD, GST, GSH, Protein thiol, and non-protein thiol levels in the treated groups when compared with group B. In immunohistochemistry, Group B exhibited over expression of CRP and NF-κB levels, and marked reduction in expression of Bcl-2 while the reverse was seen in the groups treated with methanol extracts of Abrus precatorius. Conclusion The methanol extract of Abrus precatorius plays a vital role against gentamicin induced renal damage by reducing levels of renal markers of oxidative stress, inflammation and apoptosis, enhancing enzymatic and non enzymatic renal antioxidant system, alongside an increase in Bcl-2 and a decrease in NF-κB and CRP expressions.

Abstract
The present study focuses on isolation and evaluation of the anti-cancer activity of compounds from the leaves of Abrus precatorius. The bioassay-directed strategy was adopted using chromatographic, gas chromatographic-mass spectrum analysis, nuclear magnetic resonance and X-ray crystallography techniques for purification and characterization of active cytotoxic compounds. Further, MDA-MB-231 breast cancer cell lines and 7,12-dimethylbenz (a) anthracene (DMBA) induced virgin female Sprague Dawley (SD) rats were used for in vitro and in vivo cytotoxicity evaluation. Stigmasterol hemihydrate and 9,12-Octadecadienoic acid (Z,Z)-2-hydroxy-1-(hydroxymethyl)ethyl ester or (β-monolinolein) were the two main cytotoxic constituents of leaf extract of A. precatorius, with an IC50 value of 74.2 and 13.2 µg/ml, respectively, in MDA-MB-231 cells. Additionally, the treatment with the stigmasterol and β-monolinolein as a combinatorial drug therapy in DMBA-induced female SD rats led to recovery of body weight, decreased tumor weight and volume, without any toxic side effects. Immunohistochemical examination showed extensive cell death and low proliferation in the treated tumor tissues that was confirmed by results from H and E staining, TUNEL assay and Ki-67 index as compared to control animal group. The reversion of glycoprotein, lysosomal and tumor marker enzyme levels back to near-normal levels after treatment with the plant compounds clearly demonstrated the reduction of tumor burden in these animals. This is the first report on isolation and characterization of the two active cytotoxic components from leaves of A. precatorius. Additionally, the profound cytotoxic and tumor-suppressive effect of these two compounds as a combinatorial therapy provide an alternative option for breast cancer treatment.

Anti-inflammatory mechanism of lonchocarpine in LPS- or poly(I:C)-induced neuroinflammation. Pharmacol Res 2017; 119:431-442.

Abstract
Neuroinflammation plays an important role in the progression of various neurodegenerative diseases. In this study, we investigated the anti-inflammatory effects of lonchocarpine, a natural compound isolated from Abrus precatorius, under in vitro and in vivo neuroinflammatory conditions induced by challenge with lipopolysaccharide (LPS)- or polyinosinic-polycytidylic acid (poly(I:C)). Lonchocarpine suppressed the expression of iNOS and proinflammatory cytokines in LPS or poly(I:C)-stimulated BV2 microglial cells. These anti-inflammatory effects were verified in brains of mice with systemic inflammation induced by administration of LPS or poly(I:C). Lonchocarpine reduced the number of Iba-1-positive activated microglia, and suppressed the mRNA expression of various proinflammatory markers in the cortex of LPS- or poly(I:C)-injected mice. Molecular mechanistic experiments showed that lonchocarpine inhibited NF-κB activity by reducing the phosphorylation and degradation of IκBα in LPS- or poly(I:C)-stimulated BV2 cells. Analysis of further upstream signaling pathways in LPS-stimulated microglia showed that lonchocarpine inhibited the phosphorylation of IκB kinase and TGFβ-activated kinase 1 (TAK1). Moreover, lonchocarpine suppressed the interaction of myeloid differentiation factor 88 (MyD88) and intereleukin-1 receptor-associated kinase 4 (IRAK4). These data suggest that toll-like receptor 4 downstream signals such as MyD88/IRAK4-TAK1-NF-κB are at least partly involved in the anti-inflammatory mechanism of lonchocarpine in LPS-stimulated microglia. Its strong anti-inflammatory effects may make lonchocarpine an effective preventative drug for neuroinflammatory disorders that are associated with systemic inflammation.

Abstract
The roots of Abrus precatorius (AP, Fabaceae) have traditionally been used in Vietnam and China for the treatment of inflammatory diseases such as stomatitis, asthma, bronchitis, and hepatitis. Therefore, in this study, we isolated 4-methoxylonchocarpin (ML), an anti-inflammatory compound present in AP, and studied its anti-inflammatory effects in mice with 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis. In lipopolysaccharide (LPS)-stimulated macrophages, ML was found to inhibit nuclear factor (NF)-κB activation and tumor necrosis factor (TNF) and interleukin (IL)-6 expression by inhibiting LPS binding to Toll-like receptor 4 (TLR4) in vitro. Oral administration of ML in mice with TNBS-induced colitis suppressed colon shortening and colonic myeloperoxidase activity. ML treatment significantly inhibited the activation of nuclear factor (NF)-κB and phosphorylation of transforming growth factor β-activated kinase 1 in the colon. Treatment with ML also inhibited TNBS-induced expression of IL-1β, IL-17A, and TNF. While ML reduced the TNBS-induced expression of M1 macrophage markers such as arginase-2 and TNF, it was found to increase the expression of M2 macrophage markers such as arginase-1 and IL-10. In conclusion, oral administration of ML attenuated colitis in mice by inhibiting the binding of LPS to TLR4 on immune cells and increasing the polarization of M1 macrophages to M2 macrophages.

Abstract
Endophytic fungi from marine seaweeds are the less studied group of organisms with vast medical applications. The aim of the present study was to evaluate antioxidant, antiangiogenic as well as wound healing potential of the endophytic fungus isolated from the seaweed Sargassum wightii. The morphological characters and the rDNA internal transcribed spacer sequence analysis (BLAST search in Gen Bank database) was used for the identification of endophytic fungus. The antioxidant potential of the ethyl acetate extract of endophytic fungus was assessed by, 1,1-diphenyl-2-picryl-hydrazyl radical scavenging method. The fungal extract was also analysed for reducing power, total phenolic and flavonoid content. Antiangiogenic activity of the fungal extract was studied in vitro by inhibition of wound healing scratch assay and in vivo by Chick chorioallantoic membrane assay. The endophytic fungus was identified as Cladosporium cladosporioides (Gen Bank ID - KT384175). The ethyl acetate extract of C. cladosporioides showed a significant antioxidant and angiosuppressive activity. The ESI-LC-MS analysis of the extract revealed the presence of wide range of secondary metabolites. Results suggest that C. cladosporioides extract could be exploited as a potential source for angiogenic modulators.

Abstract
Ribosome-inactivating proteins (RIPs) are enzymes that deadenylate nucleic acids and are broadly distributed in the plant kingdom. Many plants that contain RIPs are listed in the pharmacopoeias of folk medicine all over the world, mostly because of their toxicity. This review analyses the position occupied in traditional medicine by plants from which RIPs have been isolated. The overview starts from the antique age of the Mediterranean area with ancient Egypt, followed by the Greek and Roman classic period. Then, the ancient oriental civilizations of China and India are evaluated. More recently, Unani medicine and European folk medicine are examined. Finally, the African and American folk medicines are taken into consideration. In conclusion, a list of RIP-expressing plants, which have been used in folk medicine, is provided with the geographical distribution and the prescriptions that are recommended by traditional healers. Some final considerations are provided on the present utilization of such herbal treatments, both in developing and developed countries, often in the absence of scientific validation. The most promising prospect for the medicinal use of RIP-expressing plants is the conjugation of purified RIPs to antibodies that recognise tumour antigens for cancer therapy.

Abstract
Lonchocarpine is a phenylpropanoid compound isolated from Abrus precatorius that has anti-bacterial, anti-inflammatory, antiproliferative, and antiepileptic activities. In the present study, we investigated the antioxidant effects of lonchocarpine in brain glial cells and analyzed its molecular mechanisms. We found that lonchocarpine suppressed reactive oxygen species (ROS) production and cell death in hydrogen peroxide-treated primary astrocytes. In addition, lonchocarpine increased the expression of antioxidant enzymes, such as heme oxygenase-1 (HO-1), NAD(P)H:quinone oxidoreductase 1 (NQO1), and manganese superoxide dismutase (MnSOD), which are all under the control of Nrf2/antioxidant response element (ARE) signaling. Further, mechanistic studies showed that lonchocarpine increases the nuclear translocation and DNA binding of Nrf2 to ARE as well as ARE-mediated transcriptional activities. Moreover, lonchocarpine increased the phosphorylation of AMP-activated protein kinase (AMPK) and three types of mitogen-activated protein kinases (MAPKs). By treating astrocytes with each signaling pathway-specific inhibitor, AMPK, c-jun N-terminal protein kinase (JNK), and p38 MAPK were identified to be involved in lonchocarpine-induced HO-1 expression and ARE-mediated transcriptional activities. Therefore, lonchocarpine may be a potential therapeutic agent for neurodegenerative diseases that are associated with oxidative stress.

Abstract
Tibetan sheep have been observed with mineral deficiencies and marginal deficiencies in Qinghai-Tibetan Plateau. Adequate amounts of essential minerals are critical to maximize the productivity and health of livestock. The objectives of this study were to evaluate the effects of 6 months of mineral block supplementation on the antioxidants, immunity, and health of Tibetan sheep. The study was conducted in Qinghai-Tibetan Plateau. The consumed values of mineral blocks were measured. Blood samples were collected at the end of the experiment to evaluate the trace elements, malondialdehyde (MDA) and glutathione (GSH) activities, and antioxidant enzyme activities. Additionally, levels of IgA, IgG, IgM, IL-2, IL-12, tumor necrosis factor-α (TNF-α), triiodothyronine (T3), tyroxine (T4), and insulin-like growth factor-1 (IGF-1) were determined. The toxic effects of the mineral block were also monitored. For Tibetan sheep, the average consumed value of mineral block was 13.09 g per day per sheep. Mineral block supplementation significantly increased the serum levels of Mn, Fe, and Se (P < 0.01), decreased the level of MDA (P < 0.05), and increased GSH activity (P < 0.05). Additionally, the mineral block-treated sheep blood had greater total antioxidative capacity (T-AOC) and total superoxide dismutase (T-SOD) activities (P < 0.01 or P < 0.05) than control sheep. Moreover, the mineral block supplementation improved the levels IgA, IgM, and IGF-1 (P < 0.01 or P < 0.05). Additionally, there were no significant histopathological changes in the organs of Tibetan sheep after long-term treatment with the mineral block. The results demonstrated that the mineral block was non-toxic and safe; the protective effects of the mineral block might be caused by an increase in the antioxidant defense system, as well as an increase in the benefits from immunity-related parameters.

Abstract
BACKGROUND Candida albicans is one of the organisms living on the human body symbiotically, but, in hosts with low immunity it becomes one of the most pathogenic fungal organisms. Combretum zeyheri has been reported to have antifungal, antibacterial and antioxidant activities. Medicinal plants are believed to be non-toxic by the general public. Toxicity studies, however, have indicated that they are capable of causing numerous side effects, therefore, evaluation of safety is required. The objective of this study was to determine the toxicity of the antifungal constituents of Combretum zeyheri on mammalian cells. METHODS Alkaloids, saponins, flavonoids-enriched extracts and crude ethanol extracts were prepared from the leaves of Combretum zeyheri. The broth microdilution method was used to investigate for antifungal activity, with miconazole used as the positive control. The MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay was used to determine cell viability of the Candida albicans cells. The most potent extracts; the ethanol extract, alkaloids and saponins respectively, were further tested for their toxicity on sheep erythrocytes, mouse peritoneal macrophages and Jurkat T cells. RESULTS All Combretum zeyheri extracts displayed a dose-dependent antifungal activity and had IC50 values ranging from 16 μg/ml to 159 μg/ml for Candida albicans. The alkaloids, saponins and ethanol extracts were found to be non-toxic towards mouse peritoneal cells and Jurkat T cells. In the haemolysis assay, all extracts were haemolytic at varying degrees and showed their greatest haemolytic activity at the highest concentration of 5 mg/ml. The saponins were the least haemolytic, followed by the ethanol extracts and the alkaloids respectively. Although these extracts were haemolytic to some extent, they may considered safe at therapeutic concentrations since there was a large difference between the antifungal IC50 and haemolysis EC50 values, hence a large therapeutic window. CONCLUSIONS Combretum zeyheri antifungal constituents are, therefore, a potential source of lead compounds which can be developed into antifungal drugs of natural origin owing to Combretum zeyheri's effective antifungal activity and low toxicity to mammalian cells.

Abstract
Aim: Abrus precatorius leaves methanolic extract (APME) was evaluated for in vivo antihyperglycemic activity and in vitro insulinotropic effect. Materials and Methods: In vivo antihyperglycemic and insulin secretagogue activities were assessed in streptozotocin-induced diabetic rats by oral administration of APME (200 mg/kg body weight [bw]) for 28 days. In vitro insulin secretion mechanisms were studied using mouse insulinoma beta cells (MIN6-β). In vivo body weight and blood glucose and in vivo and in vitro insulin levels were estimated. Results: In diabetic rats, APME treatment significantly restored body weight (26.39%), blood glucose (32.39%), and insulin levels (73.95%) in comparison to diabetic control rats. In MIN6-β cells, APME potentiated insulin secretion in a dependent manner of glucose (3–16.7 mM) and extract (5–500 μg/mL) concentration. Insulin secretagogue effect was demonstrated in the presence of 3-isobutyl-1-methyl xanthine, glibenclamide, elevated extracellular calcium, and K+ depolarized media. Insulin release was reduced in the presence of nifedipine, ethylene glycol tetra acetic acid (calcium blocking agents), and diazoxide (potassium channel opener). Conclusion: The study suggests that APME antihyperglycemic activity might involve the insulin secretagogue effect by pancreatic beta cells physiological pathways via K+-ATP channel dependent and independently, along with an effect on Ca2+ channels. SUMMARY Abrus precatorius leaves methanolic extract (APME) showed a significant anti hyperglycemic and insulin secretagogue activities in streptozotocin induced diabetic rats. Also demonstrated a potent In vitro insulin secretagogue effect in mouse insulinoma beta cells (MIN6-β) APME treatment significantly restored body weight (26.39%), reduced blood glucose (32.39%) and enhanced circulatory insulin levels (73.95%) in diabetic rats APME demonstrated glucose and extract dose dependent insulin secretion Insulin secretagogue effect was demonstrated in the presence of 3-isobutyl-1-methyl xanthine, glibenclamide, elevated extracellular calcium and K+ depolarized media. Insulin release was reduced in the presence of nifedipine and ethylene glycol tetra acetic acid (Calcium blocking agents), diazoxide (potassium channel opener) The insulinotropic effect of APME involves a physiologic effect on K+-ATP channel and Ca2+ channels

[PMID: 26553095 PMCID: PMC4640380 DOI: 10.1186/s12906-015-0930-y] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2015] [Accepted: 11/02/2015] [Indexed: 02/07/2023]
Abstract
Background Alzheimer’s disease (AD) is a progressive neurodegenerative disorder clinically characterized by loss of memory and cognition. Cholinergic deficit and oxidative stress have been implicated in the pathogenesis of AD. Therefore, inhibition of acetylcholinesterase and oxidation are the two promising strategies in the development of drug for AD. Phyllanthus acidus, belonging to the family Euphorbiaceae, is a tree and has been used in traditional medicine to treat several pain, inflammatory and oxidative stress related disorders such as rheumatism, bronchitis, asthma, respiratory disorder, also important to promote intellect and enhance memory, thus supporting its possible anti-Alzheimer’s properties. In this study, P. acidus was evaluated for its cholinesterase inhibitory and antioxidant activities. Methods In this study, we evaluated the antioxidant potential and neuroprotective activity of P. acidus by assessing total phenol content (FCR assay), total flavonoid content, total antioxidant capacity, Fe3+ reducing power capacity, DPPH (2, 2-diphenyl-1-picrylhydrazyl) and hydroxyl radical scavenging capacity, lipid peroxidation inhibition activity & metal chelating activity. In addition acetylcholinestrase (AChE) and butyrylcholinestrase (BChE) inhibitory activities were performed using Ellman’s method. Results Total phenolic content and total flavonoid content of the extract were 116.98 mg of gallic acid equivalent and 168.24 mg of quercetin equivalent per gm of dried extract. The methanolic extract of P. acidus (MEPA) showed considerable total antioxidant activity and reducing capacity. In DPPH scavenging assay and hydroxyl radical scavenging assay, the MEPA showed 84.33 % and 77.21 % scavenging having IC50 of 15.62 and 59.74 μg/ml respectively. In lipid peroxidation inhibition activity MEPA showed moderate inhibition of peroxidation at all concentrations with IC50 value of 471.63 μg/ml and exhibited metal chelating activity with IC50 value 308.67 μg/ml. The MEPA exhibited inhibition of rat brain acetylcholinesterase and human blood butyrylcholinesterase in a dose dependent manner and the IC50 value was found to be 1009.87 μg/ml and 449.51 μg/ml respectively. Conclusion These results of the present study reveal that MEPA has considerable amount of antioxidant activity as well as anti-acetylcholinesterase and anti-butyrylcholinesterase activity which suggest its effectiveness against Alzheimer's disease and other neurodegenerative disorders.

Anticancer activity of 7-epiclusianone, a benzophenone from Garcinia brasiliensis, in glioblastoma. BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2015; 15:393. [PMID: 26518729 PMCID: PMC4628319 DOI: 10.1186/s12906-015-0911-1] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/23/2015] [Accepted: 10/12/2015] [Indexed: 01/28/2023]
Abstract
BACKGROUND Glioblastoma is the most common tumor of the central nervous system and one of the hardest tumors to treat. Consequently, the search for novel therapeutic options is imperative. 7-epiclusianone, a tetraprenylated benzophenone isolated from the epicarp of the native plant Garcinia brasiliensis, exhibits a range of biological activities but its prospect anticancer activity is underexplored. Thus, the aim of the present study was to evaluate the influence of 7-epiclusianone on proliferation, clonogenic capacity, cell cycle progression and induction of apoptosis in two glioblastoma cell lines (U251MG and U138MG). METHODS Cell viability was measured by the MTS assay; for the clonogenic assay, colonies were stained with Giemsa and counted by direct visual inspection; For cell cycle analysis, cells were stained with propidium iodide and analyzed by cytometry; Cyclin A expression was determined by immunoblotting; Apoptotic cell death was determined by annexin V fluorescein isothiocyanate labeling and Caspase-3 activity in living cells. RESULTS Viability of both cell lines was drastically inhibited; moreover, the colony formation capacity was significantly reduced, demonstrating long-term effects even after removal of the drug. 7-epiclusianone treatment at low concentrations also altered cell cycle progression, decreased the S and G2/M populations and at higher concentrations increased the number of cells at sub-G1, in concordance with the increase of apoptotic cells. CONCLUSION The present study demonstrates for the first time the anticancer potential of 7-epiclusianone against glioblastoma cells, thus meriting its further investigation as a potential therapeutic agent.

In vitro antioxidant properties, free radicals scavenging activities of extracts and polyphenol composition of a non-timber forest product used as spice: Monodora myristica. Biol Res 2015; 48:15. [PMID: 25885269 PMCID: PMC4393590 DOI: 10.1186/s40659-015-0003-1] [Citation(s) in RCA: 52] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2014] [Accepted: 02/11/2015] [Indexed: 02/08/2023] Open
Abstract
Background Excessive production of free radicals causes direct damage to biological molecules such as DNA, proteins, lipids, carbohydrates leading to tumor development and progression. Natural antioxidant molecules from phytochemicals of plant origin may directly inhibit either their production or limit their propagation or destroy them to protect the system. In the present study, Monodora myristica a non-timber forest product consumed in Cameroon as spice was screened for its free radical scavenging properties, antioxidant and enzymes protective activities. Its phenolic compound profile was also realized by HPLC. Results This study demonstrated that M. myristica has scavenging properties against DPPH•, OH•, NO•, and ABTS• radicals which vary in a dose depending manner. It also showed an antioxidant potential that was comparable with that of Butylated Hydroxytoluene (BHT) and vitamin C used as standard. The aqueous ethanol extract of M. myristica barks (AEH); showed a significantly higher content in polyphenolic compounds (21.44 ± 0.24 mg caffeic acid/g dried extract) and flavonoid (5.69 ± 0.07 quercetin equivalent mg/g of dried weight) as compared to the other studied extracts. The HPLC analysis of the barks and leaves revealed the presence of several polyphenols. The acids (3,4-OH-benzoic, caffeic, gallic, O- and P- coumaric, syringic, vanillic), alcohols (tyrosol and OH-tyrosol), theobromine, quercetin, rutin, catechine and apigenin were the identified and quantified polyphenols. All the tested extracts demonstrated a high protective potential on the superoxide dismutase (SOD), catalase and peroxidase activities. Conclusion Finally, the different extracts from M. myristica and specifically the aqueous ethanol extract reveal several properties such as higher free radical scavenging properties, significant antioxidant capacities and protective potential effects on liver enzymes.

Polyploidy Analysis and Attenuation of Oxidative Stress in Hepatic Tissue of STZ-Induced Diabetic Rats Treated with an Aqueous Extract of Vochysia rufa. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2015; 2015:316017. [PMID: 25763088 PMCID: PMC4339860 DOI: 10.1155/2015/316017] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/15/2014] [Revised: 12/23/2014] [Accepted: 12/24/2014] [Indexed: 02/06/2023]
Abstract
Diabetes mellitus (DM) is characterized by hyperglycemia and alterations in the metabolism of lipids, carbohydrates, and proteins. Due to its hypoglycemic effect Vochysia rufa is frequently used in Uberlandia, Brazil, to treat DM. Despite its popularity, there is little information about its effect on hepatic tissue. Therefore, we evaluated the histoarchitecture, oxidative stress parameters, and polyploidy of liver tissue from streptozotocin- (STZ-) induced diabetic rats treated with aqueous extract of Vochysia rufa (AEV). Histology was determined by fixing the livers, processing, and staining with HE. Oxidative stress was determined by evaluating CAT, GPx, and SOD activity in liver homogenates and hepatic mitochondria fraction and by measuring GST, GSH levels and lipid peroxidation (MDA). Polyploidy was determined by subjecting isolated hepatocyte nuclei to flow cytometry. In the diabetic group, GST activity and GSH rates decreased whereas liver homogenate analysis showed that GPx, SOD activity and MDA increased. AEV treatment restored all parameters to normal levels. The oxidative stress analysis of hepatic mitochondria fraction showed similar results. Lower polyploid cell populations were found in the diabetic rat livers, even after glibenclamide treatment. Thus, AEV treatment efficiently reduced hepatic oxidative stress caused by STZ-induced diabetes and produced no morphological changes in the histological analysis.

Abstract
Phenolic contents and antioxidant capacities from different solvent extracts (petroleum ether, ethyl acetate, methanol, butanol and water) of Aster scaber leaf were investigated. Antioxidant activity was evaluated by three different methods, namely DPPH radical scavenging activity, reducing power assay and phosphomolybdenum activity. A total of twenty-three polyphenolic compounds were identified and quantified from A. scaber leaf extracts, including hydroxybenzoic acids, hydroxycinnamic acids, flavonols and other groups of phenolic compounds. Ultra high performance liquid chromatography (UHPLC) analysis of the leaf extract revealed that myricetin (4850.45 μg/g) was the most dominant flavonols, compared to quercetin and kaempferol. Caffeic acid was the dominant phenolic compound in A. scaber leaf extracts, it constituted about 104.20 μg/g, followed by gentisic acid (84.50 μg/g), gallic acid (61.05 μg/g) and homogentisic acid (55.65 μg/g). The total phenolic and flavonoid content was the highest in ethyl acetate extract (322.43 and 6.51 mg/g). The decreasing order of antioxidant activity among the A. scaber leaf extracts assayed through all the three methods was found to be ethyl acetate > butanol > methanol > petroleum ether > water extract.
