Formulation and Evaluation of in vitro antidiabetic Polyherbal tablets form some traditional used Herbs

The main objective of the project is to formulate and evaluate poly herbal anti diabetic tablet. Polyherbal antidiabetic formulation consists of six herbs viz., Nigella sativa (seed), Moringa oleifera (seed), Linum usitatissimum (seed), Trigonella foenum(seed), Cinnamum zeylanicum (bark) and Macrotyloma uniflorum (seed). Nine preliminary clumps of tablets were defined by fluctuating the organization off the excipient’s extents for phenomenal stream property. The mixed powder of each of the nine preliminary groups were investigated for its stream attributes like mass thickness, tapped thickness, compressibility file, Hausner's proportion and Angle of rest. Absolutely nine preliminaries of plan were completed utilizing various decisions of excipients thinking about various realities of assembling issues just as quality deformities as a top priority. Every one of the resultant plans were assessed for their stream property, consistency of filling, consistency of weight, dampness substance and breaking down time. The dried polyherbal remove was streamlined for its quality measures and its cluster consistency by making nine diverse preliminary clumps (Trial 1,2,3,4,5,6,7,8,9). The preliminaries were exposed to preformulation boundaries to affirm the consistency and quality. The outcome presumes that the preliminary 9 was amazing in all boundaries and the qualities were found inside as far as possible and it was utilized for detail Polyherbal Tablet. The developed polyherbal Phytochemical study showed the presence of flavonoids in this formulation flavonoids, tannins phenolic compounds are by using qualitative phytochemicals anaylsis. The poly herbal tablets and extracts are subjected in to HPTLC analysis estimation of Quercetin and rutin. This may be responsible for the potent anti-diabetic activity. The in vitro antidiabetic activity of tablets was evaluated by glucose uptake assay by using 3T3 Cell line. Further investigations are suggested for solidness concentrates in the detailed polyherbal tablet and furthermore clinical preliminaries need to act in future in Human Volunteers

IN VITRO EVALUATION OF ANTIDIABETIC AND CYTOTOXICITY POTENTIALS OF THE RHIZOME EXTRACT OF DRYNARIA QUERCIFOLIA (L.) J. SMITH

Objective: In the present study, an attempt has been made to evaluate the in vitro antidiabetic and cytotoxic potentials of the rhizome extract of Drynaria quercifolia (L.) J. Smith. Methods: In vitro antidiabetic activity was determined by two different assays such as alpha-amylase inhibition assay and glucose uptake assay. The plant extract with three different concentrations was used for this assay. L6 rat myogenic cells were selected and subjected to glucose uptake assay. The cytotoxic activity of the different concentrations of the plant extract on HepG2 cell line was also investigated in vitro through 3-(4,5, dimethythiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. Results: The findings of the study provide evidence that the rhizome extract of D. quercifolia possesses significant anti-diabetic activity. In MTT assay, the significant cytotoxic effect of plant extract was observed by measuring the percentage of cell viability on the HepG2 cell line. Conclusion: The findings indicated that rhizome extracts of D. quercifolia have potential as a medicinal drug against diabetes mellitus (DM) and liver cancer. Further, studies with in vivo and clinical trials need to be conducted to establish rhizome extract as a safe agent for DM and liver cancer therapy.

The Cytotoxic Properties of Baeckea frutescens Branches Extracts in Eliminating Breast Cancer Cells

Breast cancer is the leading cause of cancer death in women in over 100 countries worldwide and accounts for almost 1 in 4 cancer cases among women. Baeckea frutescens of the family Myrtaceae has been used in traditional medicine and is known to possess antibacterial, antipyretic, and cytoprotective properties. In this study, we investigated the role of Baeckea frutescens branches extracts against human breast cancer cells. Baeckea frutescens branches extracts were prepared using Soxhlet apparatus with solvents of different polarity. The selective cytotoxic activity and the glucose consumption rate of Baeckea frutescens branches extracts of various concentrations (20 to 160 ug/ml) at 24-, 48-, and 72-hour time points were studied using MTT and glucose uptake assay. The IC50 values in human breast cancer (MCF-7 and MDA-MB-231) and mammary breast (MCF10A) cell lines were determined. Apoptotic study using AO/PI double staining was performed using fluorescent microscopy. The glucose uptake was measured using 2-NBDG, a fluorescent glucose analogue. The phytochemical screening of major secondary metabolites in plants was performed. This study reports that Baeckea frutescens branches extracts showed potent selective cytotoxic activity against MCF-7 cells compared to MDA-MB-231 cells after 72 hours of treatment. Evidence of early apoptosis which includes membrane blebbing and chromatin condensation was observed after 72 hours of treatment with Baeckea frutescens branches extracts. Interestingly, for the glucose uptake assay, the inhibition was observed as early as 24 hours upon treatment. All Baeckea frutescens extracts showed the presence of major secondary metabolites such as tannin, triterpenoid, flavonoid, and phenol. However, alkaloid level was unable to be determined. The identification of Baeckea frutescens and its possible role in selectively inhibiting glucose consumption in breast cancer cells defines a new role of natural product that can be utilised as an effective agent that regulates metabolic reprogramming in breast cancer.

STUDIES ON IN VITRO ANTIDIABETIC ACTIVITIES OF HOPEA PONGA AND VITEX LEUCOXYLON

<p><strong>Objective: </strong>Evaluating antidiabetic property of <em>Hopea ponga</em> and <em>Vitex leucoxylon</em> extracts by using <em>in vitro</em> assays.</p><p><strong>Methods: </strong>The exhaustive serial extraction was carried out with a series of solvents: chloroform, ethyl acetate, methanol, ethanol and water with increasing polarity using Soxhlet apparatus. The concentrated and dried extracts were evaluated for antidiabetic activity by employing standard <em>in vitro</em> techniques (α-amylase and glucose uptake assay using yeast model in which the effects of extracts on α-amylase and glucose uptake was tested by considering the percentage of inhibition of α-amylase and increase in glucose uptake in yeast cells).</p><p><strong>Results: </strong><em>In vitro</em> antidiabetic studies show that in case of <em>Hopea ponga</em> methanol extract showed comparable antidiabetic activity with percentage of α-amylase inhibition 51.7925±0.92794 % and with IC50 value 96.53 µg and it was less on comparison with standard i.e. 71.0907±0.67796% with IC50 value 70.33 µg and in case of glucose uptake assay aqueous extract showed higher activity over all remaining extracts with percentage of inhibition 49.8100±0.62476% and with IC50 value 250.95 µg. whereas in case of <em>Vitex leucoxylon</em> aqueous extract exhibited significant activity in both performed assays i. e α-amylase inhibition and glucose uptake assay with percentage 54.6147±0.46397% and 57.1337±0.44201% respectively when compared to other solvent extracts.</p><p><strong>Conclusion: </strong>Results confirm that aqueous extract of <em>Vitex leucoxylon</em> exhibited highest antidiabetic activity among all extracts. Additional studies are needed for purification, characterization and structural elucidation of bioactive compounds from aqueous extract and also confirm its antidiabetic property by <em>in vivo</em> studies. The present study provides scientific evidence that the leaves of <em>Hopea ponga and Vitex leucoxylon</em> possess anti-diabetic efficacy. Thus, considering its relative antidiabetic potency, these extracts are the useful therapeutic agents for treating and management of diabetes.</p>
