摘 要: 利用柱层析和色谱-质谱(GC-MS)技术从中国南海海绵Polymastiasobustia中分离和鉴定两种不同甾核的8个甾醇.它们分别是:胆甾烷醇、胆甾醇、胆甾-5,22-二烯-3β-醇、胆甾-5,24-二烯-3β-醇、胆甾-5,22-二烯-24-甲基-3β-醇、胆甾-24-甲基-Δ5-3β-醇,胆甾-5,22-二烯-24-乙基-3β-醇、胆甾-24-乙基-Δ5-3β-醇.这是海绵Polymastiasobutia中所含甾醇化合物的首次报道. With the use of chromatography and GC-MS,the marine sponge Polymastia sobustia collected form South China Sea was studied.The sponge contains eight sterols with two different nuclei.They are cholestanol,cholesterol,cholesta-5,22-dien-3β-ol,cholesta-5,24-dien-3β-ol,cholesta-5,22-dien-24-methyl-3β-ol,cholesta-24-methyl-Δ5-3β-ol,cholesta-5,22-dien-24-ethyl-3β-ol and cholesta-24-ethyl-Δ5-3β-ol.This is the first report of the existence of these sterols in the sponge polymastia sobustia.
