Natural Products Chemistry: Isolation and Structure Elucidation of Natural Products from Some Medicinally Important Plant Species

Plants have been one of the important sources of medicines even since the dawn of human civilization. Recently, in spite of tremendous development in the field of allopathy, plants still remain one of the major sources of drug in the modern as well as traditional system of medicine throughout the world. Over 60% of all pharmaceuticals are plant-based. In this work we tried to reinvestigate the two medicinal plants (Cynanchum acutum L.) and(Curcuma longa L.) hoping for isolation and characterization some further bioactive natural products.
