Abstract

The rhizomes of two Alpinia Species, namely Alpinia galanga and Alpinia officinarum belonging to family Zingiberaceae are well known for their traditional uses. The present research work was conducted for detailed comparative pharmacognostic and phytochemical investigation of the two species with the aim to establish the diagnostic keys for these important drugs based on the macroscopic, microscopic (histological distinction), qualitative tests, physico-chemical constants (ash and extractive values) and phytochemical analysis. All the parameters were studied according to the WHO and pharmacopoeial guidelines. The macroscopic characters of rhizomes were determined organoleptically and for microscopically. The measurement of different tissues and cell components were performed with the help of ocular, stage micrometer and camera lucida. The present study will provide the information with respect to detailed diagnostic and distinctive characteristics for the differentiation of the two Alpinia Species which can be also used as quality control parameters of these species and may provide the standard parameters to establish the authenticity of commercialized varieties and can probably help to differentiate the drug from the other species. Results obtained from this study will be helpful to generate information concerning relevant pharmacognostical, phytochemical and physicochemical data needed for proper identification and authentification of Alpinia galanga and Alpinia officinarum. It will serve as standard reference for identification and distinguishing rhizomes of two Alpinia Species from its substitutes and adulterants.
