Xyloccensin K Extracted from Xylocarpus Granatum Studied by NMR Spectroscopy
木果楝中Xyloccensin K的NMR研究

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.
