They agents1. Medicinal plants have various were reported to exhibit various effects on living systems2. Medicinal plants pharmacological activities such as CNS contents are used for the development of activity, cardiotonic activity, lipid-lowering new drug compounds that are used in the activity, anti-oxidant activity hepato- treatment of different type of diseases like protective activity, hypoglycemic activity, liver and heart problems, cancer, diabetes3, etc9.

Therefore, most of the medicinal cures urinary tract infections including plants raw materials are used for the glycosuria, haemorrhoids, fistula and worm development of new drugs4,5. These infestation. It also suppresses skin diseases. medicinal plants are used to treatment for Fruits of Albizia procera acts as astringent variety of diseases without any side effects6. and diminishes Kapha and Sukra11. In India, Albizia procera is widely leaves are poulticed on to ulcers12. Hence distributed from India and Myanmar through the present study was to evaluate the Southeast Asia to Papua New Guinea and phytochemical activity of ethanolic extract northern Australia. The habitat ranges from of aerial parts of Albizia procera Roxb. monsoon forest, mixed deciduous forest, (Benth.). savannah woodlands, pyrogenic grassland, roadsides and dry gullies, to stunted, Collection and Identification of Plant seasonal swamp forest. It is commonly materials found in open secondary forest and in areas The aerial parts of Albizia procera with a pronounced dry season. Albizia were collected from Tuliarai, Tirunelveli procera is a tree with an open canopy, up to District of Tamil Nadu, India. Taxonomic 30 m tall and trunk of 35 (60 max.)cm in identification was made from Botanical diameter; bole straight or crooked, up to 9 Survey of Medicinal Plants Unit Siddha, m. Bark smooth, pale yellowish-brown or Government of India. Palayamkottai. The brown with horizontal ridges; branches aerial parts of Albizia procera were dried terete, glabrous. Leaves bipinnate; apex under shade, segregated, pulverized by a rounded or subtruncate, often emarginate, mechanical grinder and passed through a 40 mucronate; both surfaces sparsely appressed mesh sieve. puberulous, rarely glabrous on top side. Flowers 15-30 per glomerule, sessile, Preparation of Extracts uniform, bisexual.
