Anti-oxidant activity and microscopic studies of Kumbi stem bark

Abstract

Phyto pharmaceuticals are derived from natural sources and mostly from plants. The method of cultivation, collection and harvesting mutate the concentration of secondary metabolites. So there is need of standardization of these crude drugs. The present study deals with the preliminary screening and microscopic relevance of stem bark of kumbi. Moreover the ethanolic, hydroalcholic and aqueous extracts are subjected to DPPH analysis and their anti-oxidant potential is determined.
