Description

In Indo-Pak subcontinent, there have been fairly organized efforts for pharmacological studies in the physiologically active plants constituents. Various centers have been established in both Pakistan and India for systematic studies on medicinal plants. The most recent and sophisticated amongst them is the H.E.J. Research Institute of Chemistry, International Center for Chemical Sciences, University of Karachi, where bioassay directed isolation studies of active constituents from various natural sources, especially from plants are routinely carried out. These studies have already resulted in isolation hundred of new natural products possessing potential for the treatment of serious human ailments like aids, cancer, tumor, diabetes, hypertension etc. The work embodied in this book is mainly dealt with the isolation and characterization of chemical constituents from three medicinal plants and their possible biological activities. The isolated compounds whether new or have been previously reported in the literature, were characterized by using various sophisticated spectroscopic techniques
