Abstract: 

Urginea steinhill , belongs to the family Hyacinthaceae is a well known medicinal plant. The present study was focused on the Antioxidant activity along with assessment of total Phenol, Vitamin C content of methanolic extract of two species of Urginea, U.indica and U.wightii bulbs collected from two different regions of South India, Tamilnadu and Karnataka using DPPH and ABTS method. Ascorbic acid and phenols are the major contributors of antioxidant activity in U. indica bulb which possesses significant antioxidant activity. Among the two bulb samples collected from different states of India, Sittampundi sample from Tamil Nadu(Urginea indica) reported more DPPH scavenging activity about 92.24 % than Yediyur sample from Karnataka (Urginea wightii) which is about 35.80 %. Similarly ABTS scavenging activity also more in U.indica (71.82 %) than U.wightii (9,95 %) in higher concentration respectively. The potential antioxidant activity may be due to the presence of more Vitamin C and the plant is capable of offering protection against free radical mediated damages.
