Polar extracts of the ophiuroid Ophioderma longicaudun contain unusual sterol sulfates together with a mixture of common 3β-hydroxysterol sulfates. The more polar compound has been shown to be 5β-cholestane-3α, 4α,11β,12β,21-pentol 3,21-disulfate 1. A second group of unusual compounds are disulfated 3α,21-dihydroxysteroids. After solvolysis to remove the sulfate groups they have been identified as
ophiuroid Ophioderma longicaudun的极性提取物包含不同寻常的甾醇硫酸盐以及常见的3β-羟基甾醇硫酸盐的混合物。极性更大的化合物已显示为5β-胆固醇3α,4α,11β,12β,21-戊醇3,21-二硫酸盐1。第二类不寻常的化合物是硫化的3α,21-二羟基类固醇。在溶剂分解去除硫酸根基团后,它们被鉴定为:(20 R)-5α-胆甾烷-3α,21-二醇4a,(20 R)-胆甾-5-烯-3α,21-二醇5a,(20 R 22 E)-胆甾5,22-二烯3α,21-二醇6a和(20 R)-24-甲基胆甾5,24(28)-二烯-3α,21-二醇7a。对“非硫酸化”固醇部分的分析表明存在常见的3β-羟基固醇。
