Three new steroid glycosides (evasteriosides C, D, and E), along with six known compounds, were isolated from two Pacific starfish of the genus Evasterias. Evasterioside C from E. retifera collected from the Sea of Japan was identified as (20R,22E)-3-O-(beta-D-xylopyranosyl)-24-nor-5alpha-cholest-22-ene-3beta,6beta,8,15alpha,26-pentaol 26-sulfate sodium salt. The structures of evasterioside D and E
从两个Evasterias属的太平洋海星中分离出三个新的类固醇糖苷(evasteriosides C,D和E)以及六个已知化合物。鉴定自日本海的网眼夜蛾Evasterioside C为(20R,22E)-3-O-(β-D-吡喃吡喃糖基)-24-nor-5alpha-cholest-22-ene-3beta,6beta,8 ,15alpha,26-pentaol 26-硫酸钠盐。埃希氏虫(从鄂霍次克海谢利霍夫湾采集)的叶黄素D和E的结构被确定为(20R,24S)-24-O-(β-D-吡喃葡萄糖基)-5alpha-胆甾烷-3beta ,6alpha,8,15beta,24-pentaol和(20R,24S)-3,24-di-O-(beta-D-xylopyranosyl)-cholest-4-ene-3beta,6beta,8,15alpha,24-pentaol , 分别。此外,已知化合物pycnopodiosides
