【摘要】从广西大风子的皮中分离得到两个新木脂素1和2,并通过高分辨质谱和核磁共振确定了其结构.利用多种二维核磁共振技术,包括HSQC, HMBC, DQF-COSY和NOESY谱,对其碳氢信号进行了全归属.毛细管电泳分析显示1和2均为外消旋体.更多还原

【Abstract】 Two neolignans were isolated from the bark of Hydnocarpus annamensis. Their structures were elucidated using high-resolution ESI mass spectrometry and NMR spectroscopy. The proton and carbon chemical shifts of the two compounds was assigned using 2D NMR experiments, including HSQC, HMBC, DQF-COSY and NOESY. The results of capillary electrophoresis (CE) analysis demonstrated that the two compounds are racemates.更多还原
