Flavonoids from Chiococca braquiata (Rubiaceae)
A new flavonol 4'-methoxykaempferol-7-(acetyloxy)-3,5-O-alpha-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 alpha-amirin, beta-amirin, ursolic and oleanolic acids . Their structures were established on the basis of spectroscopic methods.
