Two new oleanane triterpenoids (1-2) and one new vibsane-type diterpenoid (3), together with 7 known compounds (4-10), were isolated from the leaves of Viburnum chingii. The structures of compounds 1-3 were elucidated by means of spectroscopic methods including extensive 1D- and 2D-NMR technique. Cytotoxicity of compounds 1-10 were tested against HL-60, SMMC-7721, A-549, SK-BR-3, and PANC-1 cell lines. Compound 3 showed significant cytotoxicity against HL-60, SK-BR-3, and PANC-1 cell lines.
从缙云荚蒾叶中分离得到两个新的齐墩果烷型三萜(1-2)和一个新的维伯烷型二萜(3),以及7个已知化合物(4-10)。采用包括广泛的一维和二维核磁共振技术在内的光谱方法阐明了化合物1-3的结构。测试了化合物1-10对HL-60、SMMC-7721、A-549、SK-BR-3和PANC-1细胞系的细胞毒性。化合物3对HL-60、SK-BR-3和PANC-1细胞系显示出显著的细胞毒性。
