Determination of soluble extractives of some medicinal plants of genus Terminalia (Combretaceae) of Marathwada region in Maharashtra.

The seasonal variation of water soluble extractive, alcohol soluble extractive and ether soluble extractive have been investigated in leaves, wood and bark of Terminalia cuneata Terminalia bellerica, Terminalia chebula and Terminalia catappa. Comparative account of water soluble extractive of leaves, wood and bark of Terminalia catappa was showed high level (range from 5.15 to 7.5 %) than Terminalia cuneata (range from 3.2 to 5.8 %) , Terminalia bellerica (range from 4.25 to 6.6 %) and Terminalia catappa (range from 3.15 to 4.8 %) in all seasons. Alcohol soluble extractive of leaves of Terminalia bellerica showed higher (range from 7.2 to 7.65 %) and lower in wood of Terminalia chebula (range from 4.2 to 4.45 %). Ether soluble extractive of leaves of Terminalia catappa showed higher (range from 4.9 to 5.25 %) and lower in wood of Terminalia chebula (range from 3.75 to 4.05 %).
