The present study was carried out to elucidate free radical scavenging activity of the leaves of locally grown trees of Moringaoleifera, Basellaalba and Centellaasiatica. The total polyphenol, flavonoids, tannins, antioxidant capacityand the free radical scavenging activity were estimated. The free radical scavenging activity of the leaves of M. oleifera, B. alba and C. asiatica were assayed by using .2, 2-diphenyl-1-picrylhydrazyl (DPPH). It was found that C. asiatica showed the highest amount of phytochemicals (2.5% polyphenols, 0.741%flavonoids and 8% tannins) and also exhibited excellent antioxidant capacity and radical scavenging ability which was determined by the IC50 values. M. oleifera also exhibited comparable results as that of C. asiatica. B. alba did not prove to be a very good scavenger in comparison to the other two leaf sources. The results indicate that C. asiatica leaves could be an important source of natural radical scavengers.
