Three of these were identified to be floribundone-1(52),10-hydroxfloribundone-2 (V) and 5,7’-physcion-fallacinol (74). To the best of our knowledge, there is no prior report on the isolation of 10- hydroxyfloribundone-2 from any Senna species. 5, 7’-physcion-fallacinol reported for the first time from the plant and floribundone-1 was isolated earlier from the plant.enLeaves of Senna SopheraThesis
