Determination of alkaloid and lipid content in some medicinal plants of Genus Sesbania

The seasonal variation of alkaloids has been invest igated in leaf, bark and wood of Sesbania rostrata , Sesbania exaltata and Sesbania sesban, which are medicinally important. The leaves of Sesbania rostrata showed high level of lipid content (range 29.14 to 31.86 mg/g d ry wt.) than Sesbania exaltata and Sesbania sesban (26.53 to 28.45 mg/g dry wt. and 22.78 to 24.60 mg/g dry wt.) respectively. The leaves of Sesbania rostrata showed high level of alkaloid (1.90 to 2.69 mg/g dry wt.) than Sesbania exaltata and Sesbania sesban (1.78 to 2.40 mg/g dry wt. and 1.34 to 1.92 mg/g dry wt.) respectively.
