| 摘 要： | 建立了山竹果皮中杂氧蒽酮类化合物的快速提取、分离、鉴定方法。以无水乙醇为夹带剂，应用超临界萃取技术对山竹果皮中的杂氧蒽酮类活性化合物进行提取，快速制备色谱装置Isolera One对粗提物进行分离，得到2种杂氧蒽酮化合物，经质谱鉴定其为α-倒捻子素(α-Mangostin)和Gartanin，两者经高效液相色谱检测纯度均不低于90%，并辅以电喷雾多级串联质谱对两种化合物的碎裂规律进行了研究。

| Abstract: | A rapid determination method of the active xanthones in Garcinia mangostana was developed by supercritical fluid extraction rapid preparative chromatography-mass spectrometry.The active xanthones in Garcina mangostana were extracted by supercritical fluid extraction technology with alcohol as entrainer,and two xanthones,α-mangostin and gartanin,were separated from the crude extract through the device of rapid preparative chromatography and identified by mass spectrometry.The purity of two isolated compounds was not less than 90% via detection of HPLC/DAD.Meanwhile,the fragmentation mechanisms of two compounds were studied by electrospray ionization tandem mass spectrometry(ESI MSn). |
