Chemotaxonomic clarification of pharmaceutically important species of Cyperus L.

The evaluation of the crude herbal drug which eventually enters the pharmaceutical market is obviously of considerable importance. This operation involves the identification of the material and determination of its quality, purity and of adulterated nature of the adulterants. The present paper is based on the above objectives which confined to chemotaxonomic authentication of Cyprus rotundus L. (Nagar mootha) and its other similar species. Chemotaxonomic techniques including morphology, organoleptography, palynology, anatomy and phyto-chemical analysis were carried out in order to clarify the pharmaceutically important species of Cyperus that is Cyperus rotundus, Cyperus alopecuroides, Cyperus difformis and Cyperus niveus. It is concluded from this study that the genuine source of herbal drug Nagar Mootha is C. rotundus instead of other species. Such type of studies is the need of herbal industry to ensure validation process which applied in the manufacturing of herbal medicines and phyto- pharmaceuticals. This will provide the credibility in the regulation and grown of pharmaceutically important herbal medicines for the foreseeable.
