目的对多棘海盘车(Asterias amurensis)的化学成分进行研究。方法用色谱法分离,并用各种波谱法对化合物的结构进行鉴定。结果从多棘海盘车甲醇提取物中分离鉴定了6个化合物,其结构分别为3β-O-sulfated-cholest-5-ensodium salt(1),3β-O-sulfated-6α-ol-pregn-9(11)-en-20-one sodium salt(2),3β-O-sulfated-6α-ol-cholest-9(11)-en-23-one so-dium salt(3),3β-O-sulfated-6α,20β-diol-cholest-9(11)-en-23-one sodium salt(4),3β-O-sulfated-6α-ol-cholesta-9(11),20(22)-dien-23-one sodium salt(5),3β-O-sulfated-6α-ol-ergost-9(11)-en-23-one sodium salt(6).结论以上化合物均为首次从该种海星中获得。
Objective To study the chemical constituents of Asterias amurensis. Methods Chromatography was used to separate the compounds and their structures were identified by various spectroscopic methods. Results Six compounds were isolated and identified from the methanol extract of A. spinulosa. Their structures were 3β-O-sulfated-cholest-5-ensodium salt(1), 3β-O-sulfated-6α-ol-pregn- 9(11)-en-20-one sodium salt(2), 3β-O-sulfated-6α-ol-cholest-9(11)-en-23-one so-dium salt(3), 3β-O- Sulfated-6α,20β-diol-cholest-9(11)-en-23-one sodium salt(4),3β-O-sulfated-6α-ol-cholesta-9(11),20(22)-dien- 23-one sodium salt (5), 3β-O-sulfated-6α-ol-ergost-9(11)-en-23-one sodium salt (6). Conclusion The above compounds were obtained from this kind of starfish for the first time.
