摘要
从河南省信阳地区产冬凌草叶中分得两种新的对映-贝壳杉烯型二萜化合物,命名为信阳冬凌草甲素和乙素,经光谱和化学方法证明,它们的结构分别为1和2.
Xindongnin A and B,two new diterpenoids were isolated from the leaves of Rabdosia rubescens(Hemsl.)Hara collected in Xinyang,Henan.From spectroscopic evidences and chemical reactions the structures of the xindongnin A and B have been assigned as ent-11-hydroxy-3,7β-diacetoxy-16-kauren-6,15-dione(1)and ent-3,6β,12β-trihydro-xy-11β-acetoxy-16-kauren-15-one(2)respectively.These two new compounds appear to be the first 6-C and 7-C,11-C and 12-C simultaneously oxygenated ent-kaurenoids isolated from Rabdosia plants.
