从瘿花香茶菜Rabdosia rosthornii(Diels)Hara的叶和茎中分离出三种二萜类化合物。其中两种为已知化合物ponicidin和oridonin。另一种为新的二萜化合物。通过理化常数和光谱的分析以及衍生物的制备,测定了其结构,并命名为瘿花香茶菜甲素。
Three diterpenoids were isolated from the leaves and stems of Rabdosia rosthornii (Diels) Hara. Two of them are the known compounds ponicidin and oridonin. The other is a new diterpene compound. Through the analysis of physicochemical constants and spectra, and the preparation of derivatives, the structure was determined and named as Saponin A.
