Pharmacognostic standardization of Pimpinella tirupatiensis bal. & Subr. an endemic to eastern ghats, Tirumala hills, Andhra Pradesh

Abstract

To evaluate the pharmacognostic characters of Pimpinella tirupatiensis Bal. & Subr. leaf, stem, and root tuber. Pharmacognostic parameters like macroscopic, microscopic and powder study of this species were undertaken. Preliminary phytochemical, physiochemical analysis and fluorescent behaviour were done by using reported methods. The macroscopic study showed that the leaf was simple, deeply cordate, veins prominent. The microscopic study of leaf revealed dorsiventral type of cellular arrangement, multicellular trichomes, anisocytic stomata. The microscopic study of stem shown conjoint, collateral, open and endarch vascular bundles. Root tuber revealed diarch type of xylem. Physiochemical analysis of leaf showed total ash, water soluble ash and acid insoluble ash. In all parts, maximum extractive value was high in water than alcohol soluble. Various pharmacognostical characters would help in identification, standardization, quality control and formulation development of P. tirupatiensis.
