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
