从河南新县产的四种唇形科香茶菜属植物中分得了七个新二萜化合物和五个已知的二萜化合物。列出了这些新化合物的结构、名称、分子式、分子量、熔点、比旋光度、紫外吸收值及最主要的~(13)C—核磁共振化学位移值。简述了它们的提取、分离及结构鉴定方法。 Four new diterpene compounds and five known diterpene compounds were isolated from four species of Lamiaceae genus Caulis grown in Henan New County. The structures, names, molecular formulas, molecular weights, melting points, specific rotations, UV absorbances and the most important 13C-NMR resonance shifts of these new compounds are listed. Their extraction, separation and structure identification methods are briefly described.
