Abstract

Abstract: The present study investigated antioxidant properties, total phenolic and flavonoid contents in methanol extract of the leaf, stem bark, and fruit of Olea ferruginea Royle, Olea europaea L., and Tilia europaea L. grow naturally in the north-west Indian Himalaya. Phenolics and flavonoids content was found to be maximum in methanol extracts of stem bark and leaf (9.28 mg GAE/g fw and 14.73 mg QE/g fw, respectively) of O. ferruginea plants. Ferric reducing antioxidant power and DPPH radical scavenging activity were found to be maximum in leaf and stem bark (38.88 mM AAE/g fw and 20.31 mM AAE/g fw, respectively) of O. ferrugenia plants, whereas maximum ABTS radical scavenging activity (4.52 mM AAE/g fw) was recorded with stem bark of T. europaea plants. These tree species were found rich in natural compounds and also possess antioxidant activities. Therefore, their pharmaceutical and local uses for the health benefits are suggested.
