从越南巴豆（Croton tonkinensis GAGNEP）叶中分离得到一个新的对映贝壳杉烷型二萜化合物：ent-1 alpha-acetoxy-7 beta，14 alpha-dihydroxy-kaur-16-en-15-on。通过光谱学、X射线晶体学分析和乙酰化反应确定了其结构。
A novel ent-kaurane diterpenoid, ent-1alpha-acetoxy-7beta,14alpha-dihydroxy-kaur-16-en-15-on has been isolated from leaves of Croton tonkinensis GAGNEP. Its structure was determined by a combination of spectroscopy, X-ray crystallographic analysis and the chemical reaction acetylation.
