The investigation of chemical constituents from the branches of Calophyllum inophyllum Linn led to the isolation of a new prenylated xanthone, named caloxanthone Q (1), together with three known compounds, 2-deprenylrheediaxanthone B (2), jacareubin (3), and 6-deoxyjacareubin (4). Their structures were completely elucidated on the basis of spectroscopic methods (UV, IR, HR-ESI-MS, 1D NMR, and 2D NMR).
对红厚壳树枝化学成分的研究导致分离出一种新的异戊烯基呫吨酮，命名为红厚壳呫吨酮Q（1），以及三种已知化合物，2-去异戊烯基红厚壳呫吨酮B（2）、jacareubin（3）和6-脱氧jacareubin（4）。基于光谱方法（紫外、红外、高分辨电喷雾电离质谱、一维核磁共振和二维核磁共振）对它们的结构进行了全面解析。
