摘要: Two new flavanes, (2S)-4',7-dihydroxy-6.8-dimethylflavane (1), and (2S)-5,7-dihydroxy-4'-methoxy-8-methylflavane (2), together with five known flavanes, (2S)-3',7-dihydroxy-4'-methoxy-8-methylflavane (3), (2R)-4',7-dihydroxy-8-methylflavane (4), (+/-)-3',7-dihydroxy-4'-methoxyflavane (5), (+/-)-4',7-dihydroxy-3-methoxyflavane (6), and (2S)-4',7-dihydroxyflavane (7), were isolated from the stem of Dracaena cambodiana. Their structures were determined by spectroscopic techniques (UV, IR, 1D and 2D NMR). Their antimicrobial activities were preliminarily examined by the filter paper disc agar diffusion method.
