从中国南海采集的幼纯短指软珊瑚、螺旋短指软珊瑚中首次分离到一个新的神经酰胺Sinumeramide(1),利用波谱方法推导其结构;同时还通过臭氧化反应以及氘硼化反应在双键上引入氘原子后的质谱分析确定其双键的位置;应用核磁共振谱及构象分析确定1的赤型构型。此外,从短指软珊瑚(未定种)中首次分离得N-乙酰二氢鞘氨醇。 A new ceramide, Sinumeramide (1), was isolated from the juvenile soft-shelled soft coral and the soft-shelled coral of the South China Sea for the first time. Its structure was deduced by spectroscopic methods. Ozonization and deuteronation Double bond on the introduction of deuterium atoms after mass spectrometry to determine the position of the double bond; Application of nuclear magnetic resonance spectroscopy and conformation analysis to determine a red type configuration. In addition, N-acetyl sphinganine was first isolated from the short-finger soft coral (undetermined species).
