Abstract

Medicinal plants used in Indian ayurveda were having potential for antimicrobial and antioxidant and anti-diabetic properties. Here different solvent extracts of Actinopteris radiata plant were studied for antioxidant, anti-diabetic and antimicrobial activities. Ethanolic extract of plant at a dose of 100μg/ml was found to be having more DPPH inhibition activity than 50μg/ml concentration of standard Ascorbic Acid. Anti diabetic activity was found to be more in aqueous extract. More than 70% amylase inhibition was observed for aqueous extract. Ethanolic extract has shown more anti-microbial activity on bacteria (B subtilis, S aureus, P aeruginosa, S typhi,) and fungi (A niger and C albicans). Further, study need to be carried for the determination of active components responsible for these biological activities.

Keywords: Actinopteris radiata, biological activities, antioxidant activity, anti-diabetic activity, antimicrobial activity.
