Determination of in vitro anti-oxidant activity of Kasmard ( Cassia sophera Linn) leaves.

Summary The antioxidant activities of aqueous, ethanol, and Pet. ether extracts of the leaves of cassia sophera Linn, were determined by the thiocyanate method using the linoleic acid emulsion. Ether extract was the most effective antioxidant among the extracts. Like antioxidant activity, the scavenging power of ether extract was the highest and aqueous extract was the lowest. The results obtained in the present study indicate that the leaves of cassia sophera are a potential source of natural antioxidants. In addition, we could suggest that although the scavenging activity of an extract may be an indicator of its potential antioxidant activity, it is important to evaluate this plant in detail with other methods. Phytochemical isolation of the ether extract for active antioxidant moiety will be the further scope for the study.
