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.
從廣西大風子的皮中分離得到兩箇新木脂素1和2,併通過高分辨質譜和覈磁共振確定瞭其結構.利用多種二維覈磁共振技術,包括HSQC,HMBC,DQF-COSY和NOESY譜,對其碳氫信號進行瞭全歸屬.毛細管電泳分析顯示1和2均為外消鏇體.

Two neolgnans 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 compunds was assigned using 2D NMR experiments, including HSQC,HMBC, DQF-COSY and NOESY.The results of caplillary electrophoresis (CE) analysis demonstrated that the two compounds are racemates.
