摘要
本文报道从国产清香桂(Sarcococca ruscifolta)和金丝矮陀陀(Pachysandra axillaria)植物中分得的三个胺碱型新甾体生物碱清香桂碱 D 和矮陀陀胺碱 A、B 的化学结构,并首次归属了它们的^(13)C NMR 数据。
In this paper,three new alkaloids,sarcorucinine D(1),and pachyaximine A,B (2,3)we- re isolated from Sarcococca ruscifolia Stapf and Pachysandra axillaris Franch,respectively.The structures of sarcorucinine D(1)and pachyaximine A,B(2,3)were elucidated to be 3β- hydroxyl-20α-dimethylamino-5α-pregnane(1);and 3β-methoxyl-20α-dimethylamino-pregne- 5-ne(2);and 3β-methoxyl-16-hydroxyl-20α-dimethylaminopregne-5-ne(16-hydroxyl-pachyaxi- mine A)(3),respectively.
