Abstract
Pharmacognostical and preliminary phytochemical studies of Triphala churnam were carried out. The churnam of triphala consists of equal quantities of deseeded fruits of Terminalia chebula, Terminalia bellerica and Emblica officinalis. Triphala is exclusively used in more than 200 drug formulations in Indian system of Medicine. The present study involved the pharmacognostical evaluation of Triphala, in which morphological and powder microscopical characters were established. In addition, physico-chemical parameters such as ash values viz, total ash (10.21± 0.42), acid insoluble ash (2.54 ± 0.06), water-soluble ash (5.46±0.24) and sulphated ash (13.12 ± 0.63), extractive values viz, alcohol soluble extractive (11.20±0.18)) and water-soluble extractive (52.56±2.04), fluorescent analysis and microchmical tests were determined. The preliminary phytochemical study revealed the presence of carbohydrates, reducing sugar and tannins in aqueous extract and carbohydrates, flavonoids and tannins in alcoholic extract. This standardization would be very much helpful for the identification of Triphala churnam to differentiate from other powdered sources.
