Abstract :

The antioxidant potential of six important Indian medicinal plants V. negundo, V. trifolia, T. bellerica, T. chebula, E. officinalis and A. racemosus were evaluated. Extracts prepared using solvents of varying polarity were screened for their free radical scavenging and reducing capacity by chemical assays. Total phenolic content was determined in order to assess its effect on the antioxidant activity of the extract. The properties of extracting solvents affected the measured total phenolic content and antioxidant activity. Extracts of all the six medicinal plants exhibited antioxidant potential but T. bellerica , T. chebula, E. officinalis proved more active. The presence of antioxidant activity in the extracts showed that these plants have the potential to be an alternate source of natural antioxidants. In vivo study is needed for successful commercialization and to benefit the food and pharmaceutical industries.
