ABSTRACT In this present study preliminary phytochemical investigation was done and free radical scavenging activity of methanolic leaves extract of D. regia were determined by using in vitro assay model of DPPH free radical scavenging activity. Ascorbic acid is used as reference standard. Flavonoid is confirmed in the extract. The extract has shown better scavenging effect and antioxidant property at higher doses when compared with standard ascorbic acid. Further investigations are needed in terms of isolation and confirmation of antioxidant effect of specific compounds leading to a possibility of being useful in the modern medicine in future.
