南海豆荚软珊瑚Lobophytumsp.化学成分的研究(二)

STUDIES ON THE CHEMICAL CONSTITUENTS OF THE SOFT CORAL LOBOPHYTUM SP.FROM SOUTH CHINA SEA

从中国南沙海域采集的豆荚软珊瑚 (L obophytum sp.)中分离得到两个甾醇 C30 H5 0 O和 C2 8H5 0O4。利用 IR,NMR,MS等波谱和光谱技术 ,确定了它们的结构分别为柳珊瑚甾醇 (1) ,(2 4S) 3β,5β,6α,2 5 -四羟基 - 2 4-甲基胆甾醇 (2 )。其中 (2 )

Two known compounds C 30 H 50 O and C 28 H 50 O 4 have been isolated from the soft coral Lobophytum sp.collected from South China Sea.Their chemical structures have been identified by IR,MS,NMR as Gorgosterol(1)and (24S)24 Methylcholestane 3β,5β,6α,25 tetrol(2).Compoumd(2)was first isolated from Lobophytum sp.of South China Sea.
