DETERMINATION OF ACID INSOLUBLE ASH VALUES OF SOME MEDICINAL PLANTS OF GENUS SESBANIA

Abstract

The seasonal variation of total ash, acid soluble ash and acid insoluble ash have been investigated leaves , wood and bark of Sesbania rostrata, Sesbania exaltata  and Sesbania sesban , which are medicinally important. Comparative account of total ash, acid soluble ash and acid insoluble ash content of bark of Sesbania rostrata showed high level of total ash ( range 7.98 %  to 8.70 % ) and low level of total ash of leaves of Sesbania sesban ( range 6.34 % to 6.78 % ) . The acid soluble ash showed higher level of bark of Sesbania rostrata (range 7.45 % to 7.74 %) and lower in wood of Sesbania sesban (range 2.62 % to 2.83 %). Comparative account of acid insoluble ash of bark of Sesbania rostrata showed higher (range 1.91 % to 2.24 %) and lower in the wood of Sesbania sesban (range 0.37 % to 0.58 %).
