Flavonoids from Ficus sarmentosa var. henryi.

Objective To investigate the chemical constituents of Ficus sarmentosa var. henryi. Methods Column chromatographic techniques were used to isolate and purify the chemical constituents. NMR was employed for their structures. Results Eleven flavonoids were isolated and identified as the following:eriodictyol (1),homoeriodictyol (2),quercetin (3),dihydroquercetin (4),kaempferol (5),dihydrokaempferol (6),naringenin (7),luteolin (8),apigenin (9),chrysoeriol (10),and 3',5',5,7-tetrahydroxylfavanone (11). Conclusion Compounds 1—11 are isolated from this plant for the first time.
