Abstract

Two novel sterols have been isolated from Spongia obligue collected from South China sea and their structure were identified as 24(28)-methylene-1,3,4,11-tetrohydroxycholest-5-en-18-oic acid and 24(28)-methylene-cholestene-5-en-1,3,8,11-tetraol respectively on the basic of the spectral data of MS, IR, 1HNMR and 13CNMR(DEPT).

摘要

从中国南海采集的扁海绵中分离出两种新型甾醇，基于质谱（MS）、红外光谱（IR）、核磁共振氢谱（1HNMR）和核磁共振碳谱（13CNMR，DEPT）的光谱数据，它们的结构分别被鉴定为24(28)-亚甲基-1,3,4,11-四羟基胆甾-5-烯-18-酸和24(28)-亚甲基-胆甾-5-烯-1,3,8,11-四醇。
