Eight new complex flavanones with a novel linkage, cryptoyunnanones A-H (-), together with four known α-pyrones, were isolated from the leaves and twigs of . The structures of - including their absolute configurations were characterized by spectroscopic data analysis and single-crystal X-ray crystallography. Plausible biosynthetic pathways for the formation of compounds - were proposed. Compounds - exhibited cytotoxicity against HCT-116, MDA-MB-231, and PC-3 cancer cells with IC values from 6.4 to 9.1 μM.
从……的叶子和嫩枝中分离出了8个具有新型连接方式的新的复杂黄烷酮,即隐云南酮A - H(-),以及4个已知的α - 吡喃酮。通过光谱数据分析和单晶X射线晶体学对隐云南酮A - H的结构包括其绝对构型进行了表征。提出了化合物隐云南酮A - H形成的合理生物合成途径。化合物隐云南酮A - H对HCT - 116、MDA - MB - 231和PC - 3癌细胞表现出细胞毒性,IC值为6.4至9.1 μM。
