Phyto–chemical screening and in vitro antioxidant activity of Merremia umbellata (Hallier. f.)

Mrs. K. Kaveri, Dr. Jeyabalan Govidasamy

Abstract :

Antioxidants play the essential role in reducing the free radicals. Aqueous extract of Merremia umbellata (Hallier. f.) was studied for its in vitro antioxidant activity using different models of screening viz. DPPH and ABTS radical scavenging activity, reducing power ability and Superoxide anion radical scavenging. The extract showed a good dose dependent free radical scavenging property in all the models. Phytochemical analysis revealed the presence of major phyto compounds like alkaloids, flavonoids, phenol and terpenoids. Its antioxidant activity was estimated by IC50 value and the values are 86.5 µg/ml (DPPH radical scavenging), 30.1 µg/ml (ABTS radical scavenging), and 40.3 µg/ml (Superoxide anion radical scavenging). The antioxidant property may be related to the polyphenols and flavonoids present in the extract. It indicates that the aqueous extract of the plant has the potency of scavenging free radicals in vitro and may provide leads in the ongoing search for natural antioxidants to be used in treating diseases related to free radical reactions
