A number of studies have focused on the biological activities. Total phenols and flavonoids possesses a broad spectrum of chemical and biological activities including radical scavenging properties (P. Padmanaba and S.N. Jangle, 2012). Sroka, (2005) have focused his studies on the biological activities of phenolic compounds which are antioxidants and free radical scavengers. In these studies have revealed presence of numerous chemicals including alkaloids, steroids, phenols, glycosides and saponins. It has been suggested that there is an inverse relationship between dietary intake of antioxidant rich foods and incidence of human diseases. These facts have inspired widespread screening of plants for possible medicinal and antioxidant properties and the utilization to antioxidants of natural origin to prevent
