Pharmacognositical and phytochemical analysis of stem bark of Albizzia lebbeck Benth

Abstract

Albizzia lebbeck Benth. is one of the significant plant of Ayurveda, belongs to the family Fabaceae. Ethno medicinally A. lebbeck is claimed to be used in the management of leprosy, wound, asthama, urticaria, migraine, worm infection and others. The present study has been carried out to establish the stem bark of the plant for its morphological, microscopical and physicochemical characters along with different phytochemical qualitative tests, as per Ayurvedic Pharmacopoeia of India. Microscopy of the stem bark showed dead tissue of rhytidoma, prismatic crystals of calcium oxalate, and tangential bands of ceratenchyma. Physicochemical parameters showed loss on drying (7.15%w/w), ash value (4.05%w/w), acid insoluble ash (0.33%w/w), water soluble extractive (15.46%w/v) and alcohol soluble extractive (14.24%w/v). Preliminary phytochemical analysis for the presence of various functional groups revealed the presence of flavonoids, proteins, saponins, tannins and free amino acids. The observed data can be useful to identify and standardize of stem bark of Albizzia lebbeck Benth.
