摘 要:Pterocarine (1), a new diarylheptanoidal compound, was isolated from Pterocaryatonkinesis (Franch.) Dode. together with a known diarylheptanoid, myricatomentogenin (2), througha bioassay-guided fractionation procedure. The structure of 1 was elucidated as (+)-3 , 4 -epoxy-1-(4 -hydroxyphenyl)-7-(3 -hydroxyphenyl)-heptane-3-one by the spectroscopic *** (1) inhibited the proliferation of tsFT210, HCT-15 and K562 cells with the inhibitionrates of 20.2±2.4, 23.8±2.4 and 50.5±1.2% at 100 μg/mL, respectively. Flow cytometric analysisindicated that 1 could inhibit the cell cycle of tsFT210, HCT-15 and K562 cells at the G0/G1 phaseand could also induce apoptosis in HCT-15 (19%) and K562 (11%) cells.
