在鄂北贝母 Ｆｒｉｔｉｌｌａｒｉａ　ｅｂｅｉｅｎｓｉｓ鳞茎非生物碱的继续研究中，又分得６种对映－贝壳杉烷型二萜，经理化常数及波谱解析，并与标准品对照，证实晶Ⅰ ～Ⅲ的结构分别为 ｅｎｔ－ｋａｕ－１５－ｅｎ－１７－ｏｌ，ｅｎｔ－ｋａｕｒａｎ－１６β，１７－ｄｉｏｌ，ｅｎｔ－ｋａｕｒａｎ－１６ α，１７－ｄｉｏｌ。晶Ⅳ Ｃ_(２２)Ｈ_(３６)Ｏ_(４)，ｍｐ １６３℃～１６４℃，经波谱分析及降解反应，鉴定其结构为 ｅｎｔ－３β-ａｃｅｔｏｘｙ－ｋａｕｒａｎ－１６ β， １７－ｄｉｏｌ，命名为鄂贝醇（ｆｒｉｔｉｌｌｅ－ｂｅｉｎｏｌ）， Ⅰ～Ⅲ在该植物中系首次分得。Ⅳ系首次发现的新天然产物。晶 Ⅴ和晶Ⅵ为聚合二萜，其结构正在鉴定中。 In the further study of bulb non-alkaloids of Fritillaria ebeiensis in northern Hubei, six enantio-kaurane diterpenes were also assigned, and the managerial constants and spectral analysis were analyzed and compared with the standard samples to confirm the crystal I-III. The structures are ent-kau-15-en-17-ol, ent-kauran-16β, 17-diol, ent-kauran-16 α, 17-diol, respectively. The crystal IV C_(22)H_(36)O_(4), mp 163°C~164°C, was identified by spectral analysis and degradation reaction as ent-3β-acetoxy-kauran-16 β, 17-diol, and was named Fritille-beinol, I-III was first isolated in this plant. IV is the first new natural product discovered. Crystal V and crystal VI are polymeric diterpenes and their structures are being identified.
