ABSTRACT

The objective of this study to find out the DPPH scavenging (antioxidant) activity of dry extract of Memecylon umbellatum Inflorescence obtained by various solvents such as petroleum ether, chloroform, ethyl acetate, acetone, methanol and chloroform water (IP). The in-vitro free radical scavenging activity was recorded by DPPH method using various concentrations of dry extract in distilled water (1, 2, 4, 8, 16, 20μg/ml) against blank with ascorbic acid as a standard in same concentrations. From among the extract the methanol extract showed maximum antioxidant activity at 20μg/ml while petroleum ether shows minimum. The IC50 value of methanol extract was found to be 12.51±1.04μg/ml as compare to standard ascorbic acid 3.76±0.0856μg/ml. By using Graphpad Instat 3 software paired ‘t’ test of methanol inflorescence extract exhibits significant results (p<0.05) compared to standard ascorbic acid. In future it may found as a main source for dietary antioxidants and nutrient.

Keywords: Memecylon umbellatum, DPPH reagent, Antioxidant activity, IC50.
