Flavonoids from Chiococca braquiata (Rubiaceae)

A new flavonol 4′-methoxykaempferol-7-(acetyloxy)-3,5-O-α-L- rhamnoside (1), was isolated from the leaves of Chiococca braquiata, along with three known flavonoids apigenin, 7-O-methoxyquercetrin and quercetrin and four triterpenes α-amirin, β-amirin, ursolic and oleanolic acids . Their structures were established on the basis of spectroscopic methods.
