Phytochemical Analysis and In vitro Antioxidant Studies of Plumeria obtusa L. Leaves

Plumeria (Apocynaceae) is a genus comprising mostly of lactiferous trees and deciduous shrubs. Plumeria obtusa L. is a widely available but pharmacologically lesser explored species of this genus. Thus, present research was undertaken to determine the phytochemical constituents and the antioxidant potential of the methanol extract and fractions of the plant. The antioxidant potential was determined using 1,1-diphenyl-2-picrylhydrazyl radical scavenging and inhibition of lipid peroxidation assay.
