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
The present attempt has been made to evaluate, and examine the levels of minerals in serum and liver in DEN induced hepatocellular carcinoma in wistar albino rats for possible chemopreventive effect. In hepatocellular carcinogenesis complications such as hepatic fibrosis and cirrhosis may lead to several abnormalities in mineral metabolism, hence attempt is made to evaluate on the level of minerals. Hepatic cancer was induced by single dose of intraperitoneal injections of DEN (200mg/kg body weight) followed by phenobarbital of 0.05% mixed with drinking water for 20 weeks. Concentration of calcium, magnesium, sodium and potassium were assessed in the serum and liver at the end of experimental period. Negative correlations were observed between liver function tests and serum mineral levels, except with albumin. Calcium, magnesium, potassium and sodium concentrations in the serum were decreased after the induction of hepatic cancer. The liver calcium content was increased after DEN treatment. No change occurred in liver sodium content. However, magnesium and potassium content was significantly reduced in the hepatic tissue. The results suggest that in DEN-induced hepato cellular carcinoma alteration of essential elements is noted. The low levels of albumin and the related ascites may be one of the major causes of the imbalance of mineral metabolism in hepatocellular carcinoma.
