Pharmacognostic standardization and phytochemical screening of albizzia lebbeck

Pharmacognostic standardization and phytochemical screening of albizzia lebbeck

Pharmacognostical standardization and phytochemical screening of Albizzia lebbeck leaves were assessed. Transverse section of Albizzia lebbeck leaves shows an upper and lower single horizontal layered epidermis followed by spongy parenchyma on both lower and upper surfaces, parenchymatous cells are thin-walled with intercellular space. Bundle sheath is present surrounding vascular bundle consist 8-10 layers of parenchymatous cells. Phytochemical screening of ethyl acetate, ethanolic and water maceration extracts of leaves shows presence of different chemical constituents like alkaloids, tannins, carbohydrates, flavanoids, proteins and Amino acids. Foaming index is less then 100 which indicate 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 alcohol soluble extractives show more water soluble constituents in the leaves.

Pharmacognostic validation of root of Hemidesmus indicus (Linn.) R.Br.

Pharmacognostic validation of root of Hemidesmus indicus (Linn.) R.Br.

Hemidesmus indicus (Linn.) R.Br. Family: Asclepiadaceae, is commonly known as ‘Indian sarasaparilla’. A perennial climber and growing widely in upper Gangetic plains and eastwards of Bengal and from central to southIndia. It is traditionally used for curing various ailments like stomach pain, fever, veneral disease, rheumatism and also act as a blood purifier. This traditionally useful part was standardized based on the macroscopic, microscopic, physico-chemical and chromatographic. And also estimated for its microbial limits ,pesticides, Aflatoxin and heavy metals. Preliminary phytochemical screening confirms the presence of sapnonins, tannins, resins, essential oils, sterols and glycosides determination of total saponin content.
