PHARMACOGNOSTIC EVALUATION OF CISSUS QUADRANGULARIS L. STEMAbstract
Cissus quadrangularis L. (Vitaceae) is a common perennial climber also called Asthisamhara meaning bone setter is prescribed both in Ayurveda as well as Unani systems for its medicinal use. Pharmacognostic evaluation of Cissus quadrangularis stem revealed a stomatal index of 151 with Stephanocytic stomata in the epidermal peeling. The anatomical section of the stem showed deposits of characteristic acicular or needle shaped calcium oxalate crystals, raphides and intrafasicular cambium. The histochemical studies showed the presence of alkaloids, tannins, phenols and suberin. The phytochemical analysis of aqueous, petroleum ether and dichloromethane extracts were positive for alkaloids, phenol, steroids, flavanoids in all the extracts. The presence of sclerides, fiber sclerides epidermal cells, phloem with companion cells, ray fibers with pits, raphides, acicular and sand crystals of calcium oxalate were evident in powder analysis. Under 365nm UV green fluorescent emission was observed in acetic acid and methanol treated stem powder.
