Physical and Phytochemical Screening of Boerhaavia diffusa L. Roots.

Nishi Saxena, and Ameeta Argal

Boerhaavia diffusa L.root powder was studied for macroscopic, micromeretic & phytochemical parameters. It was coarse, light brown powder with very few foreign organic matters. Angle of repose, bulk density and tapped density showed passable flow property due to uneven shape and rough surface. The total ash, acid insoluble ash and water soluble ash values were within IP limit showing the purity of drug. Alcohol soluble and water soluble extractive values were found to be 18.6% & 23.2% w/w respectively. The phytochemical investigation showed the presence of carbohydrates, alkaloid, protein, terpenoid and flavanoid in both aqueous and alcoholic extract. The presence of these constituents is responsible for the wide medicinal use of Boerhaavia diffusa L. roots.
