摘要

从中国南海软珊瑚Sarcophyton tortuosum中分离到一种新的多羟基甾醇——扭曲肉芝甾醇A(Sartortaosterol A)

通过化学反应和四谱法推定其化学结构为24ξ-甲基-5α-胆甾烷-3α

6β

9α-

25-四醇-25-乙酸酯.

Abstract

A novel polyhydroxylated steroid

sartortuosterol A

with rare 3a- and separated 6β- and 9α-hydroxyl groups

was isolated from the Chinese soft coral Sarcophyton tortuosum Tixier-Durivault. The steroid is a glass-like crystal with a formula C

m.p. 227-9℃ and [a]

+48.05. From the IR

NMR data and comparing with its derivatives from Jones oxidation and then dehydration

the steroid was designated as 24- methyl 5α-cholestane-3α

6β

9α

25-tetrol 25-monoacetate.
