Pharmacognostic and physicochemical standardization of leaves of Glycosmis pentaphylla (Retz.) DC
Pressy P Prakasia and Ashalatha S Nair
The present study was undertaken with an objective to investigate the pharmacognosy of the crude drug powder of the leaf of Glycosmis pentaphylla an ethno-medicinally important plant belonging to orange family (Rutaceae). Pharmacognostic evaluations were conducted in terms of macroscopic, microscopic, physicochemical and micromeritics analysis according to the WHO and other recommended procedures. The characteristic macroscopic and microscopic features of leaf include presence of oil globules on upper epidermal region, endarch xylem, amphicribral vascular bundles and anomocytic stomata. The Physicochemical analysis reveals values for moisture content, pH, ash values and extractive values which are within the World Health Organisation (WHO) standards for crude drug from medicinal plants. Micromeritic analysis of leaf powder reveals good flow properties of powder which is an important criterion in the manufacture of tablets and capsules. The results of the macroscopic and microscopic evaluations of Glycosmis pentaphylla leaf furnish diagnostic features for judging the authenticity, quality, purity and also to differentiate the drug from its closely related species and also to detect adulterants. The present study on pharmacognostic standardisation, physicochemical evaluation of Glycosmis pentaphylla leaf might be useful to supplement information in regard to its identification parameters assumed significantly in the way of acceptability of herbal drugs in present state of affairs.
