Pharmacognostic standardization and phytochemical screening of albizzia lebbeck

Abstract

Pharmacognostical standardization and phytochemical screening of Albizzia lebbeck leaves were assessed. Transverse section of Albizzia lebbeck le aves shows an upper and lower single horizontal layered epidermis followed by spongy par enchyma on both lower and upper surfaces, parenchymatous cells are thin-walled with intercell ular space. Bundle sheath is present surrounding vascular bundle consist 8-10 layers of parenchymatous cells. Phytochemical screening of ethyl acetate, ethanolic and water mac eration extracts of leaves shows presence of different chemical constituents like alkaloids, tan nins, carbohydrates, flavanoids, proteins and Amino acids. Foaming index is less then 100 which i ndicate presence of saponins in leaves which finally proves by quantitative determination of total saponin 1.4% and total flavanoids 0.6%. Water soluble extractives are more then alcoh ol soluble extractives show more water soluble constituents in the leaves.
