In-Vitro Determination of Antioxidant Capacity for Methanolic extract of Eichhornia crassipes, Lawsonia inermis L. and Cissus quadrangularis L

Abstract

Among the most used medicinal plants Eichhornia crassipes, Cissus quagragualis L.and Lowsonia inermis L. are very common. There were a goodmany work on these plant, but the antioxidant activity is not so satisfactory. To justify their antioxidant activity leaf of Lowsonia inermis L., whole plant of Cissus quagragualis L and leaf of Eichhornia crassipes were taken. Their Methanolic extract was used and tested their antioxidant activity by DPPH Free radical scavenging assay (Quantitative analysis). Ascorbic acid was used as standard here. Activity of Cissus quagragualis L (IC 50 = 11.3163 μg/ml) and Lowsonia inermis L (IC 50 = 17.0689 μg/ml) are quite seticfactory. They have strong antioxidant activity. But, Eichhornia crassipes (IC 50 =186.1196 μg/ml) gives almost no activity.
