Pharmacognostic specifications of eight cultivars of Piper betle from eastern region of India

In present study eight cultivars of Piper betle were compared with their distinguishing morpho-anatomic details of leaf, dissociation and powders. The microscopic features were systematically described and illustrated. The physiochemical properties such as loss on drying, total ash value, acid insoluble ash value, water soluble ash value and extractive values were also carried out. HPTLC analysis of petroleum ether extract and essential oil showed confirming the presence of compound in Piper betle cultivars leaf. And detailed key authentication parameters based on these anatomic characteristics were presented. The various morphological, microscopical, physicochemical standards can be unambiguously used to authenticate standardization and distinguish eight cultivars of Piper betle.
