Shankar D. Katekhaye,
Kirti S. Laddha.
Prenylated flavonoids such as 3'prenyl-apigenin (1), 2-(4-hydroxy-3,5-bisisoprenyl)-8,8-dimethyl[2,3]pyrano)
flavanone (2), 2(8'8'-dimethyl[2,3]pyrano-3,4-dehydro-cyclohexane)flavanone (3) and 2-(3'-isoprenyl)-4-oxocyclohexyl)-
4H-chromene-4,5,7(4aH,6H)-trione (4) were isolated from Pithecellobium dulce. Structures of isolated phytoconstituents
were elucidated on the basis of spectroscopic analysis and physicochemical properties.
Keywords: Characterization, Pithecellobium dulce, isolation, phytoconstituents, prenylated flavanoid.
