摘要:

从南海小月柳珊瑚Menella sp. 石油醚萃取部位中分离得到7个孕甾烷类化合物, 通过波谱分析并与文献对照, 其结构分别鉴定为 3α-羟基-5β-孕甾-20-酮(1), 3β-羟基-5α-孕甾-20-酮(2), 3β-羟基-孕甾-5-烯-20-酮(3), 5β-孕甾-3, 20-二酮(4), 5α-孕甾-3, 20-二酮(5), 孕甾-4-烯-3, 20-二酮(6), 孕甾-1, 4-二烯-3, 20-二酮(7); 除化合物2外其他化合物都为首次从该属柳珊瑚中分离得到, 其中化合物7是首次报道其核磁数据。

Abstract:

Seven pregnane steroids were isolated from the petroleum ether extracts of a South China Sea gorgonian Menella sp. collected in the Sanya Bay. By means of spectroscopic analysis and comparison with literatures, their structures were identi-fied as 3α-hydroxy-5β-pregnan-20-one (1), 3β-hydroxy-5α-pregnan-20-one (2), 3β-hydroxy-pregnan-5-en-20-one (3), 5β-pregnan-3, 20-dione (4), 5α-pregnan-3, 20-dione (5), pregnan-4-en-3, 20-dione (6), and pregnan-1, 4-dien-3, 20-dione (7), respectively. All compounds except compound 2 were isolated from this genus for the first time, and the NMR data of com-pound 7 was reported for the first time.
