Two coumarins named as bergapten and seselin along with three flavonoids named as 5-methoxy-4'- hydroxy-6,7-methylenedioxyisoflavone,5 ,4'-dihydroxy- 6,7-methylenedioxyisoflavone and 5.7.4'-trihydroxy-3'6 dimethoxyisoflavone have been isolated from leaves of Cassia siamea. Their structure have been elucidated on the basis of chemical and spectral evidences ['H-NMl7, IR, UV, and Mass]
