摘要:

首次对南海柳珊瑚Leptogorgia rigida中甾体类次生代谢产物进行研究。采用硅胶柱柱层析、十八烷基硅烷键合硅胶填料、Sephadex LH-20、高效液相色谱(HPLC)及薄层色谱(TLC)等多种方法进行分离纯化, 通过核磁共振波谱(NMR)、质谱(MS)等现代波谱分析及物理常数对照等方法进行结构鉴定。从南海柳珊瑚Leptogorgia rigida次生代谢产物中分离得到8个甾类化合物, 结构依次为: 3β, 6β, 11-trihydroxy-9, 11-seco-5α-chloest-7-en-9-one (1); 3β, 6α, 11- trihydroxy-9, 11-seco-5α-chloest-7-en-9-one (2); 3β, 6α, 11-trihydroxy-5α-chloest-7, 22(E)-dien-9-one (3); pregnan-4-en-3, 20-dione (4); 5α-pregnan-3, 20-dione (5); 3β-hydroxy-pregnan-5-en-20-dion (6); 3β-hydroxy-5α-pregnan-20-one (7); 和3β, 6α, 11-trihydroxy-9, 11-seco-5α-gorgosterol (8)。所有化合物均首次从Leptogorgia属中得到。

Abstract:

Research was carried out on novel secondary metabolites from Leptogorgia rigida collected from the South China Sea. The secondary metabolites were isolated by silica gel column chromatography, ODS, Sephadex LH-20, thin layer chromatography, and high performance liquid chromatography (HPLC). The structures of compounds were identified by nuclear magnetic resonance spectrum (NMR), mass spectrum (MS), and literature analysis. Eight sterols were obtained and elucidated as follows: 3β, 6β, 11-trihydroxy-24-methyl-5α-chloest-9, 11-seco-7-en-9-one (1); 3β, 6α, 11-trihydroxy-24- methyl-5α-chloest-9, 11-seco-7-en-9-one (2); 3β, 6α, 11-tri- hydroxy-5α-chloest-9, 11-seco-7, 22(E)- dien-9-one (3); pregnan- 4-en-3, 20-dione (4); 5α-pregnan-3, 20-dione (5); 3β-hydroxy- pregnan-5-en-20-dione (6); 3β-hydroxy-5α-pregnan-20-one (7); and Gorgosterol (8). All the sterols were first obtained from Leptogorgia rigida.
