摘要: A new homoisoflavonoid, named cambodianol (1), together with the two known flavanes, (2S)-7,3'-dihydroxy-4'-methoxy-8-methylflavane (2) and (2R)-7,4'-dihydroxy-8-methylflavane (3), were isolated from the stems of Dracaena cambodiana. Their structures were determined based on HR-ESI-MS and spectroscopic techniques (UV, IR, 1D-, and 2D-NMR). Compound 1 exhibited significant cytotoxic activities against K562 and SGC-7901 with the IC50 values of 1.4 and 2.9g/ml, respectively.
