1 Department of Pharmacognosy, The Oxford College of Pharmacy, Bangalore 560078, Karnataka, India
Abstract
The antioxidant activity of the methanol extract of leaves of Hyptis suaveolens Poit. was evaluated in vitro by 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity using gallic acid and butylated hydroxyanisole (BHA) as reference standards. They exhibited strong antioxidant radical scavenging activity with IC50 value of 0.4, 1.15 and 14.04 μg mL-1 for Gallic acid, BHA and Hyptis suaveolens, respectively. The antioxidant activity of methanol extract could be due to the presence of Flavonoids.
