摘要
从云南省中甸县产叶穗香茶菜[Rabdosia phyllostachys(Diels)Hara]叶中分得1个新二萜化合物,命名为叶穗香茶菜乙素(phyllostachysin B),经各项波谱数据确定,叶穗香茶菜乙素为6β,11β,14β—三羟基-15α-乙酰氧基-对映-贝壳杉-16-烯-20 醛-7-酮。另一个为已知化合物叶穗香茶菜甲素(phyllostachysin A)。
A new diterpenoid, phyllostachysin B(l) together with known compound phyllostachysin A were isolated from the ethereal extract of the leaves of Rabdosia phyllostachys (Buch-Kam. ex D.Don) Hara (Labiatae) collected in Yunnan, China. The structrue of (1) was established as 6β, 11β, 14β-trihydroxy-15α-acetoxy-ent-kaur-16-en-20-aldehyde-7-one.
