Abstract:

Two new ent kauranoids, tenuifolin A (3β,6α,15β-trihydroxy-1α,7β-diacetoxy- 11β,16β-epoxy-ent-kaurane) (1) and tenuifolin B (1α,6α,11β-trihydroxy-3β, 7β-diacetoxy-ent-kaur-16-en-15-one) (2), together with four known compounds were isolated from the aerial parts of Isodon tenuifolia (W. W. Smith) Kudo collected from Zhongdian County, Yunnan Province, China. Their structures were determined by the spectral methods (including 2D NMR techniques).

从云南中甸产细叶香茶菜(Isodon tenuifolia (W. W. Smith) Kudo)的地上部分分离得到6个化合物, 它们的结构通过波谱方法得到鉴定。其中化合物1和2为新的对映-贝壳杉烷二萜化合物, 即细叶香茶菜甲素(3β,6α,15β-trihydroxy-1α,7β-diacetoxy-11β,16β-epoxy-ent-kaurane) (1) 和细叶香茶菜乙素(1α,6α,11β-trihydroxy-3β,7β-diacetoxy-ent-kaur-16-en-15-one) (2)。
