摘要
One new 2-arylbenzofuran derivative, artocarstilbene B（1）, one new benzaldehyde derivative,（E）-3,5-dihydroxy-4-（3-methylbut-1-enyl）benzaldehyde（2）, as well as 18 known compounds（3–20） were obtained from the leaves of Artocarpus heterophyllus. Their structures were elucidated on the basis of extensive spectroscopic techniques including 2D NMR and HR-ESIMS. Many compounds exhibited moderate to weak inhibitory activity against the proliferation of the PC-3, NCI-H460, and A549 cancer cell lines.
