中国南海软珊瑚Nephthea　bayeri化学成分研究——一种类脱皮激素五 ?

Studies on the Chemical Constituents of the Chinese Soft Coral Nephthea bayeri

从南海软珊瑚Ｎｅｐｈｔｈｅａｂａｙｅｒｉ中分离得到７种结晶性化合物，通过ＩＲ，ＭＳ，１ＨＮＭＲ，１３ＣＮＭＲ和ＵＶ波谱技术以及化学方法、理化常数，推导了它们的结构．报道其中一种类脱皮激素的多羟基甾醇——２α，３β，１５，１６，１９－五羟基－Δ４。

Seven crystalline compounds have been isolated from the Chinese soft coral Nephthea bayeri collected from the South China Sea. Their structures were elucidated with the date of IR, MS, 1H NMR, 13 C NMR, UV and chemical methods. An ecdysone like polyhydroxysterol2α,3β,15,16,19 pentahydroxy △ 4,7 6 ketone 24 methylene cholesterol was reported.
