摘要
从疏花毛萼香茶菜 (Isodoneriocalyxvar.laxiflora)叶中分离得到一新的对映 -贝壳杉烷型二萜 ,命名为疏花丁素 (1) ,通过波谱方法鉴定了它的结构。此外 ,还分离得到 6个已知对映 -贝壳杉烷型二萜化合物 :疏花甲素 (2 ) ,毛萼晶A -C (3～ 5)和Q (6 ) ,毛萼乙素(7) ,以及cirsimaritin (8)和 2α -羟基乌索酸 (9)。
A new ent -kauranoid named laxiflorin D (1) was isolated from the leaves of Isodon eriocalyx var. laxiflora , whose structure was determined by the spectroscopic methods. Six known ent -kaurane diterpenoids, laxiflorin A (2), maoecrystals A-C (3～5), Q (6) and eriocalyxin B (7), together with cirsimaritin (8) and 2α-hydroxyursolic acid (9), were also isolated.
