نبذة مختصرة
To study chemical constituents contained in roots of Caesalpinia millettii by HPLC. Six homoisoflavonoids were identified by spectroscopic data and physicochemical property as eucomin (1), intricatinol (2), 8-methoxybonducellin (3), bonducellin (4), 8-methoxyisobonducellin (5) and 3-(4-methoxybenzyl) -5, 7-dimethoxychroman-4-one (6). All compounds were separated from the root of this genus for the first time. An antibacterial screening was made on eight monomeric compounds. Among them, 8-methoxyisobonducellin, intricatinol, bergenin, hyperoside and 11-O-galloylbergenin showed a inhibitory effect on Staphylococcus aureus, Klebsiella Peneumoniae, Beta streptococcus and Aeruginosus bacillus.
