摘要
从采自西藏的皱叶香茶菜中分离鉴定了3对B-闭联对映贝壳杉烯型二萜化合物:二萜化合物皱叶香茶菜素(Ⅰ)和二氢皱叶香茶菜素(Ⅱ);isodocarpin(Ⅲ)和dihydroisodocarpin(Ⅳ)及Carpalasionin(Ⅴ)和dihydrocarpalasionin(Ⅵ)。(Ⅰ)、(Ⅲ)和(Ⅴ)分别与对应的二氢化合物(Ⅱ)、(Ⅳ)和(Ⅵ)以混合物的形式被分离和鉴定。化合物(Ⅱ)为新化合物,(Ⅰ)、(Ⅳ)和(Ⅵ)首次在自然界发现,(Ⅲ)和(Ⅴ)为已知化合物。
Three pairs of B- seco- ent- kaurene type diterpenoids were isolated from Rabdosia rugosa (Wall. )Hara collected from Tibet, and the structures of them were elucidated. They are diterpenoids rugosanin(Ⅰ ) and dihydrorugosanin (Ⅱ ), isodocarpin( Ⅲ ) and dihydroisodocarpin (Ⅳ ), carpala-sionin(Ⅴ) and dihydrocarpalasionin (Ⅵ). ( Ⅰ ), (Ⅲ) and (Ⅴ) were isolated, respectively, in the. form of mixtures with their corresponding dihydrocompounds ( Ⅱ ), (Ⅳ ) and ( Ⅵ ). The structure identification was based on the mixtures of each pair. Diterpenoid (Ⅱ ) is a new compound; ( Ⅰ ), (Ⅳ ) and ( Ⅵ) are for the first time found in nature, ( Ⅲ ) and ( Ⅴ ) are known compounds.
