Peltophorum pterocarpum (DC.) Baker ex. K. Heyne Flowers: Antimicrobial and antioxidant efficacies

Abstract

Peltophorum pterocarpum, a large tree of wide occurrence, posses varied medicinal properties. In the present study, its flowers were successively extracted with pet. ether, dichloromethane, ethyl acetate and methanol and screened for their potential antimicrobial and antioxidant efficacies. In antibacterial screening, ethyl acetate fraction exhibited maximum activity against S. aureus and E. aerogenes (IZ 16.00±0.57 and 15.33±0.32 mm, respectively), while dichloromethane fraction was found active against it!, planticola and E. aerogenes (IZ 15.66±1.19, 14.66±0.66 mm, respectively). In antifungal screening, ethyl acetate fraction showed appreciable activity against T. rubrum and P. crysogenum (IZ 15.00±0.00 mm). The 6.5 jig mL-1) as compared to the standard (quercetin). From the results it is evident that the flowers of P. pterocarpum. However, in antioxidant screening, methanol fraction showed highest activity (RC50 possess very potent antimicrobial and antioxidant efficacies. © 2011 Academic Journals Inc.
