ABSTRACT

The thrust on utilization of bioactive chemicals from plant sources is known since ancient times. Plants are rich in bioactive compounds and are used to cure a wide range of ailments, in the form of crude preparations in Ayurveda and Siddha, and Unani. The most commonly used four medicinal plants are selected for the present study. The plant phytochemicals are extracted using water and methanol separately and concentrated on water bath. In vitro antioxidant activity is done by DPPH radical scavenging activity and ABTS radical cation decolourization assay. In addition, the estimation of bacterial inhibition against five bacteria are done; three are gram positive and two are gram negative inorder to know the antioxidant activity related bacterial inhibition. The medicinal plants that are used showed maximum antioxidant property and maximum inhibition against the test organisms.

Keywords: phytochemicals, analysis, antioxidant related antibacterial activity.
