ABSTRACT
The pharmaceutical sector is focused on development of new drugs and plant based drugs through investigation of leads from traditional system of medicine Ayurveda which is being practiced for thousands of years. Bauhinia variegata is a species of flowering plant in the family Fabaceae. Bauhinia variegata is native to southeastern Asia, from southern China west to Pakistan and India. The major chemical constituents of the plant was found to beflavone, 5,7-dimethoxy-30, 40-methylenedioxy flavone and a new dihydrodibenzoxepin,5,6-dihydro-1,7-dihydroxy-3,4-dimethoxy-methyldibenzoxepin, flavonolglycoside, triterpene saponin, phenanthraquinone, flavonoids.

Bauhinia variegatais found as chemoprotective antitumor activity, hepatoprotectivity,anti-inflammatory, anti-mutagenicity, anti-diabetic,antinociceptive, antioxidant and antihyperlipidemicetc.,In our present investigation we propose to isolate the major phytochemical constituents from Bauhinia variegate to carry out structural characterization by analytical methods for the isolated phytochemical constituents.
