Preliminary phytochemical and pharmacognostical studies on cnicus wallichii DC

ABSTRACT

The leaves and stems of Cnicus wallchii DC family Asteraceae [Compositae] were studied to determine the pharmacognostical standards. The investigation was carried out on macro and microscopical characters of leaf and stem, powder microscopy, fluorescence analysis, leaf constants like vein islet number, vein termination number, stomatal number, stomatal index and study of physical constants like ash values, extractive values and preliminary phytochemical evaluation
