Methods Various chromatographic techniques were used to separate the constituents and their structures were elucidated on the basis of extensive spectroscopic interpretation. Results Six compounds were isolated from the root barks of M. alba. The structure of new compound, named as albafuran D(1), was established together with known compounds sanggenon H(2), kuwanon E(3), kuwanon U(4), kuwanon F(5), and benzokuwanon E(6). Conclusion Compound 1 is a new geranylated 2-arylbenzofuran.展开更多
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...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.展开更多
