Antioxidant properties of methanolic extract of oxalis corniculAta


                The whole plant oxalis corniculata (Oxalidaceae) has been used traditionally in folk medicine for treating anaemia wounds, cancer, piles. The methanolic extract of oxalis corniculata (MEOC) have been proven experimentally to possess antioxidant activity in invitro methods. MEOC showed effective response on 2,2-Diphenyl-1-picryl-hydrazyl radical (DPPH) method for determining the free radical scavenging activity. The plant contain majorly c-glycosyl flavones and rich in Vit-C. The concentration of plant extract required for 50% inhibition of DPPH radical scavenging effect (IC50) were recorded as 30 mg/ml and 37 mg/ml for MEOC and standard ascorbic acid. These results suggest that the MEOC possess antioxidant activity compared to ascorbic acid.

Key words: Oxalis corniculata, DPPH, Vit-C, Antioxidants, Scavenging activity.
