Two new flavonoids, named cambodianins D (1) and E (2), together with two known flavanes (2S)-7,4-dihydroxy-6,8-dimethylflavane (3) and (2S)-7,3-dihydroxy-4- methoxy-8-methylflavane (4) were isolated from dragons blood of Dracaena cambodiana. The new compounds were determined by HR-ESI-MS and spectroscopic techniques (UV, IR, 1D and 2D NMR). Compounds 1 ~ 3 exhibited antimicrobial activities.
