摘要: 从疏花毛萼香茶菜(Isodon eriocalyx var. 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)。

Abstract: A new ent - kauranoid named laxiflorin D (1) was isolated from the leaves of Isodon eriocalyx var. hxifhra, whose structure was determined by the spectroscope 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 2a- hydroxyursolic acid (9), were also isolated.

Key words: Isodon eriocalyx var.laxiflora
