摘要
Aim To study the chemical constituents of starfish Asterias amurensis. Methods The constituents were separated and purified by different chromatographic methods, and their structures were elucidated by MS and NMR. Results Six compounds were isolated from Asterias amurensis Lutken. Their structures were identified as 3β-O-sulfated-cholest-5-en sodium 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 sodium 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 ）, and 3β-O-sulfated-6ct-ol-ergost-9 （ 11 ） -en-23- one sodium salt （6）. Conclusion Compounds 1 - 6 were obtained from this species for the first time.
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。
