Eight new acridone alkaloids, buxifoliadines-A--H together with nine known acridone compounds, were isolated and characterized from the root bark of Severinia buxifolia which was collected in Hainan province, China. Their structures were determined by spectroscopic methods. The relationship between acridone alkaloids with collecting area is discussed. The 13C-NMR spectra of the prenyl substituents at C-2 and/or C-4 of N-unsubstituted acridone alkaloids are also discussed.
从采自中国海南省的海南酒饼簕根皮中分离并鉴定出8个新的吖啶酮生物碱——酒饼簕啶-A - H，以及9个已知的吖啶酮化合物。通过光谱方法确定了它们的结构。讨论了吖啶酮生物碱与采集区域之间的关系。还讨论了N-未取代吖啶酮生物碱C-2和/或C-4位异戊烯基取代基的13C-NMR谱。
