EXPERIMENTALPHYTOPHARMACOGNOSY

There is remarkable progress in Natural drugs and derived product inventions. Rapiddevelopment in the isolation purification processes and in identification of structures with novelbiodynamic effects has led to new chemical entity paths for drug discovery. Over hundred ofactive chemical substances exist that have been isolated from natural sources and which aresuccessfully used as ingredients in foods medicines and in cosmetics. The goal of modernphytochemical research is to isolate the active constituents and fractions from natural sourcesused in traditional medicines and evaluate them so as to meet the international standards ofquality and therapeutic efficacy.
