ABSTRACT
OBJECTIVE@#The present work tested organic solvents to prepare an extract with anticancer properties from a polyherbal mixture containing Nigella sativa (seeds), Hemidesmus indicus (roots) and Smilax glabra (rhizomes). We evaluate anticancer effects in non-small-cell lung cancer cells (NCI-H292), and discuss optimization for pharmaceutical use in the context of efficacy, yield and toxicity.@*METHODS@#Using different organic solvents, six extracts were prepared from the polyherbal mixture. Based on the cytotoxic effects of these extracts on NCI-H292 cells and normal lung cells (MRC-5), as evaluated by the sulphorhodamine B assay, the total ethyl acetate (T-EA) extract was selected for further analysis. The possible anticancer mechanisms were assessed by evaluating the extract's effects on apoptosis (through fluorescent microscopic analysis, DNA fragmentation analysis, caspase 3/7 assay and analysis of expression levels of apoptosis-related genes p53, Bax, survivin, Hsp70 and Hsp90), colony formation and antioxidant activity.@*RESULTS@#The extract had cytotoxic effects against NCI-H292 cells in a time- and dose-dependent manner. Significant antioxidant activity and inhibition of colony formation were also observed. The expression level of caspase 3/7 significantly (P < 0.001) increased in NCI-H292 cells treated with 50 μg/mL of the extract. The same dosage led to a significant increase in expression levels of Bax and p53 (P < 0.05 and P < 0.01 respectively), accompanied by a significant decrease (P < 0.0001) in survivin, Hsp70 and Hsp90.@*CONCLUSION@#T-EA extract of the above polyherbal mixture has cytotoxicity against NCI-H292 cells via induction of apoptosis, antioxidant effects and inhibition of colony formation.
ABSTRACT
BACKGROUND : Hemidesmus indicus is one such important herb popularly known as Indian sarasaparilla It is said to possess analgesic effect AIM:The present study investigates the analgesic activity of the crude extract of Hemidesmus indicus METHODS: Analgesic effect was evaluated using Eddys hot plate and Tail clio method in mice . Institutional animal ethical clearance was obtained RESULTS: The analgesic effect was seen following oral administration of aqueous and ethanolic extract of Hemidesmusindicus, shown prolongation of reaction time and reduction in the number of attempts to dislodge the tail clip by mice. The hot plate method showed a statistically significant prolongation in the reaction time. The effects of both aqueous and ethanolic extract of Hemidesmus indicus are comparable with that of diclofenac sodium
ABSTRACT
Many forms of alternative medicines were available for those who cannot be helped by conventional medicine. Ayurvedha and Herbal medicine were two important forms of alternative medicine that was widely available in India. This work was mainly concerned with the identification of the therapeutic properties of Hemidesmus indicus. The ethanolic extract of hemidesmus indicus root was used for its anti oxidant and antimicrobial activity. Hemidesmus indicus root extract has very well anti oxidant and anti microbial activity. The ethanolic extract of Hemidesmus indicus was checked for anti microbial activity against pathogenic bacteria such as staphylococcus aures, pseudomonas aeruginosa and fungi Aspergillus niger.
ABSTRACT
Peptic Ulcers are the most common condition experienced by most of the people due to urbanized lifestyle. Hemidesmus indicus R.Br. is a herbal drug mentioned for its treatment in the ancient Indian traditional medicine. To compare the Prophylactic and Curative effects of aqueous and Alcoholic extracts of Hemidesmus indicus in Drug induced ulcers. Aqueous and Alcoholic extracts of the drug were studied for their ulcer healing activity in Wistar Albino rats. Ninety Wistar albino rats were divided into nine groups with one control, four prophylactic and four curative groups. Ulcers were induced with Indomethacin in a dose of 20 mg/kg body weight twice in a gap of 15 hours. Aqueous extract was given in a dose of 500 mg/kg body weight and alcohol in a dose of 100 mg/kg body weight. It was found that both have potential ulcer healing activity with alcoholic extract marginally better than aqueous extract. It can thus be concluded that Hemidesmus indicus R. Br is a effective drug in peptic ulcers.
ABSTRACT
Background: Herbal drugs used to treat illness according to Ayurveda are often misidentifi ed or adulterated with similar plant materials. Objective: To aid taxonomical identifi cation, we used DNA barcoding to evaluate authentic and substitute samples of herb and phylogenetic relationship of four medicinal plants of family Asparagaceace and Asclepiadaceae. Materials and Methods: DNA extracted from dry root samples of two authentic and two substitutes of four specimens belonging to four species were subjected to polymerase chain reaction (PCR) and DNA sequencing. Primers for nuclear DNA (nu ITS2) and plastid DNA (matK and rpoC1) were used for PCR and sequence analysis was performed by Clustal W. The intraspecifi c variation and interspecifi c divergence were calculated using MEGA V 4.0. Statistical Analysis: Kimura’s two parameter model, neighbor joining and bootstrapping methods were used in this work. Results: The result indicates the effi ciency of amplifi cation for ITS2 candidate DNA barcodes was 100% for four species tested. The average interspecifi c divergence is 0.12 and intraspecifi c variation was 0.232 in the case of two Asparagaceae species. In two Asclepiadaceae species, average interspecifi c divergence and intraspecifi c variation were 0.178 and 0.004 respectively. Conclusions: Our fi ndings show that the ITS2 region can effectively discriminate Asparagus racemosus and Hemidesmus indicus from its substitute samples and hence can resolve species admixtures in raw samples. The ITS2 region may be used as one of the standard DNA barcodes to identify closely related species of family Asclepiadaceae but was noninformative for Asparagaceae species suggesting a need for the development of new markers for each family. More detailed studies involving more species and substitutes are warranted.
