PHARMACOGNOSTICAL, PHYSICO-CHEMICAL AND PRELIMINARY PHYTOCHEMICAL ANALYSIS OF WHOLE PLANT OF PIPER LONGUMAbstract
This study deals with the Pharmacognostical physicochemical and phytochemical evaluation of the whole plant of Piper longum L. Pharmacognostical studies includes macroscopic, microscopic, and physicochemical evaluation. Physicochemical constants showed the values of total ash (10%), acid insoluble ash (1%), water-soluble ash (32%), sulphated ash (22%), nitrated ash (18.5%), hot extraction (11.2%), water-soluble extractive (4.8%), ethanol-soluble extractive (12.4%), ether soluble extractive (5.6%), loss on drying (29%), swelling index (0.33) and mucilage content (0.8%) w/w. The preliminary phytochemical screening of the alcoholic extract showed alkaloids, phenolic compounds, tannins, mucilage, starch, steroid, and flavanoids. This study helps to development of different standard parameters of the plant, which help the plant identification and authentication.
