ABSTRACT
Objective: The objective of the present research work had been made to evaluate the antioxidant potential along with anti-cancer activity of methanolic extracts from the leaf of A. marmelos. Methods: Standard methods for antioxidant potential in terms of DPPH and nitric oxide scavenging assay, and anticancer activity in vitro method (Cytotoxicity/MTT assay and % of cell viability) by using MCF7 cell line. Results: Results of antioxidant efficacy revealed that the IC50 value for DPPH and nitric oxide scavenging assay was considered to be 62.032%, and 20.69% respectively. The methanolic extract of A. marmelos was found to possess enhanced anticancer potential against MCF7 cells. Cytotoxicity activity of MCF7 cells, when treated with methanolic extract of A. marmelos, was found to be 43.42% at 25µg, 52.31% at 50µg, 56.31% at 75µg, 58.38% at 100µg, 62.25% at 125µg. The IC50 value was found as 49.36µg. Toxicity was significantly increased with increased concentration and viability significantly decreased with the increased concentration of methanolic extract of leaf from A. marmelos for MCF7 cell when compared to cyclophosphamide. Conclusion: From the studies, it was postulated that methanolic extract of leaf from A. marmeloshas significant chemopreventive activity. These specific identities will be useful for the identification and authentication of raw drug.
ABSTRACT
In Malaysia, Monopterus albus is commonly found in rice fields, muddy ponds and swamp areas. Channa striatus have been widely used as a source of traditional medicines. The extracts of Malaysian local Monopterus albus and Channa straitus have been reported to have different bioactive properties and these properties can be used at molecular level as alternative tool for different disorders. The comparative analysis of antibacterial, antifungal, antiproliferative and CRE induced expression of downstream luc gene activities of both the extracts were performed. The bacteriostatic and antibacterial effects of both extracts were revealed beside higher antifungal activity of Channa straitus. The extracts from Monopterus albus showed higher levels of antiproliferative activity as compare to Channastraitus. The results were found supportive towards up regulation of hrluc by Monopterus albus extracts and down regulation by Channa striatus extracts. This is the first report on comparing the bioactive properties of Monopterus albus and Channa straitus. The results from this study demands a further research on identifying the bioactive molecules involve in these actions at a molecular level.
