Twenty-two sterols were identified in the starfish Asterias rubens (Phylum, Echinodermata; Class, Asteroidea). 2. The major 4-demethyl sterols had a Delta(7) bond and the C(27) compound 5alpha-cholest-7-en-3beta-ol predominated over other mono- and di-unsaturated sterols belonging to the C(26), C(27), C(28) and C(29) series. 3. Small amounts of cholest-5-en-3beta-ol and 5alpha-cholestan-3beta-ol were also present. 4. The minor sterols identified all contained either one or two methyl groups at C-4 and are considered to be potential biosynthetic precursors of 5alpha-cholest-7-en-3beta-ol. 5. Three sterols possessing a 9beta,19-cyclopropane ring were also isolated and were probably derived by the starfish from a dietary source.

在红海盘车（门，棘皮动物门；纲，海星纲）中鉴定出了22种甾醇。2. 主要的4-去甲基甾醇具有Δ⁷键，并且C₂₇化合物5α-胆甾-7-烯-3β-醇比属于C₂₆、C₂₇、C₂₈和C₂₉系列的其他单不饱和及双不饱和甾醇更为常见。3. 还存在少量的胆甾-5-烯-3β-醇和5α-胆甾烷-3β-醇。4. 鉴定出的次要甾醇在C-4位均含有一个或两个甲基，被认为是5α-胆甾-7-烯-3β-醇的潜在生物合成前体。5. 还分离出了三种具有9β,19-环丙烷环的甾醇，它们可能是海星从食物来源中获取的。
