POONAM GAWALI AND B. L. JADHAV

Abstract

The antioxidant activity and antioxidant phytochemicals in the stem and leaves of S.alba and B. cylindrica species of Mumbai coast were studied. Present results have confirmed scavenging free radicals potentials of B.cylindrica and S. alba. IC50 values for DPPH radical scavenging activity of stem and leaves of S.alba was 62.5 and 87.5μg/mL while for B.cylindrica it was 162.5 and 175μg/mL respectively. The reducing power of all the extract of both the plant increased dose-dependently in which S.alba showed higher reducing power. Among the antioxidant phytochemicals both the plant revealed presence of flavonoids, tannins, triterpenes, anthraquinones, alkaloids and saponins.
