摘要
从红树植物木果楝的果实中分离并鉴定了2个limonoid类化合物XyloccensinK和6acetoxycedrodrorin,应用高分辨NMR技术对XyloccensinK的1H和13CNMR数据进行了准确的归属,并纠正了文献中部分碳氢信号归属的错误.
Two limonoid compounds, xyloccensin K and 6-acetoxycedrodrorin, were isolated from the fruit of xylocarpus granatum. Their structures were elucidated by 1D and 2D NMR spectroscopy. It was shown that previous chemical shift assignment for some of the ^1H and ^13C signals of xyloccensin K＇is incorrect. Correction was made for the incorrect assignment.
