Abstract

Effect of season on in vitro antioxidant activity of Abutilon indicum Linn (A. indicum L.) leaves was studied. Leaves of A. indicum L. of different seasons were collected from the medicinal plant garden of the North Bengal University and identified by the taxonomist. In vitro antioxidant activity of the leaves was measured by superoxide anion generation with the help of xanthine-xanthine oxidase assay, linoleic acid peroxidation assay and DPPH photometric assay. Amount of total phenols present in the leaves of different seasons was also estimated. Results showed that in vitro antioxidant activity of the leaves of A. indicum L. was maximum during summer (March – May) in comparison to other seasons of the year. Amount of total phenols present in the leaves was also found maximum in summer. In vitro antioxidant activity of A. indicum L. leaves, therefore, was due to high amount of total phenols in the leaves. Leaves of A. indicum L. of summer may be further investigated to get natural antioxidant compound.

Keywords: Abutilon indicum Linn leaves, in vitro antioxidant activity; total phenols, effect of season.
