摘要: 较系统的总结了贝壳杉烷型四环二萜的13C NMR数据,探讨了其13C NMR的规律和特征.并在此基础上报道了一个新的贝壳杉烷型四环二萜化合物——对映-16β,17,18-三羟基-贝壳杉烷-19-羧酸。

Abstract: The 13C NMR chemical shifts of a series of kauran tetranuclear diterpene compounds which were published in the past years were reviewed, their regularity and characteristics were summarized. It was found that C16, C17 and C18 seem to be substituted by hydroxyl group and their chemical shifts were affected by the configuration.We also found that C19 tend to be substituted by carboxyl group.
This characteristic was applied for confirming the structure of a new compound-ent-16β,17,18-trihydroxy-kauran-19-oic acid. Its structures was verified by IR, MS and 1H NMR.

Key words: Kauran tetranuclear diterpene, 13C NMR, Ent-16β,17,18-trihydroxy-kauran-19-oicacid
