Out of 35 plant extract screened, 15 showed radical scavenging activity in both DPPHand ABTS +• assays. In the present investigation, Aleurites trispesma, Elaeocaspus multiforus, Livestona chinensis and Nagia nagi showed the very strong radical scavenging activity in both DPPH and ABTS assays. However, extracts of plants such as Syzygium jambos, Grevillea robusta, Terminalia bovinii, Elaeocarpus serratus, Tabebuia pentaphylla, Fraxinus griffithii, Machilus zuihoensis, Artocarpus incisus, Cajanus cajan and Corchorus aestuand showed moderate antioxidant activity. The IC50 values of these plant extracts were also calculated and compared.
