ABSTRACT

Pharmacognostic studies mainly helps in plant identification and it lays the standard parameters which not only help but also prevents adulterations. Pharmacognostic studies will help in authentication of the medicinal plants and ensures in reproducible quality of plant products which lead to efficacy and safety of plant material. So, an attempt was made to study pharmacognostic parameters and phytochemical screening of Crinum asiaticum and Pedalium murex. The pharmacognostic parameters mainly include macroscopical, powder microscopy, quantitative leaf microscopy (stomatal number, stomatal index, vein – islet number and vein termination number and palisade ratio), physiochemical parameters (total ash, water soluble ash, acid insoluble ash, water soluble extractive value, acetone soluble extractive value and alcohol soluble extractive value), fluorescent analysis and phytochemical screening of ethanol, acetone and aqueous extracts of Crinium asiticum and Pedalium murex.

Keywords: Crinum asiaticum, Pedalium murex, ethanol, acetone and aqueous.
