Determination of soluble extractive of some medicinal plants of Genus Sesbania

The seasonal variation of water soluble extractive alcohol soluble extractive and ether soluble extrac tive have been investigated in leaves, wood and bark of Sesbania rostrata , Sesbania exaltata and Sesbania sesban . Comparative account of water soluble extractive of leaves, wood and bark of Sesbania rostrata was showed high level (range from 3.53 to 6.43%) than Sesbania exaltata (range from 3.26 to 6 .02 %) and Sesbania sesban (range from 2.73 to 5.67 %) in all seasons. Alcohol soluble extractive of leaves of Sesbania rostrata showed higher (range from 6.97 to 7.78 %) and lower in bar k of Sesbania sesban (range from 3.90 to 4.34 %). Ether soluble extractive of leaves of Sesbania rostrata showed higher (range from 3.90 to 4.43 %) and lower in bark of Sesbania sesban (range from 1.85 to 2.11 %).
