高效液相色谱-质谱联用技术分析刺五加抗疲劳化学成分

High-performance liquid chromatography combined with mass spectrum analysis for identifiying the antifatigue components in Acanthopanax senticosus Harms

刺五加粗提物经植化方法处理后,采用液相质谱(LC/MS/MS)联用技术进行分析。得到了LC/MS/MS联用的分析条件,取得较好分离效果,确定了数种已知及未知的化合物的所在部位。在其中一个部位,即11号样品中,发现5个已知成分和相对分子质量分别为302、318、346、354、390、406的6个未知成分。

The roots of Acanthopanax senticosus(Rupr. et Maxim.) Harm were obtained for the acquisition of the crude extra- ctives to isolate the 19 components by means of preliminary extraction and isolation. High-performance liquid chromatography followed by primary and secondary mass spectrum analysis (HPLC/MS/MS) was employed to identify the antifatigue components from the extracts of the plant with reference to the literature. Good isolation results were achieved and several known and unknown chemical compounds were identified, for instance, in one sample (No. 11) 5 known components were detected along with 6 unknown compounds with relative molecular mass of 302, 318, 346, 354, 390, and 406, respectively.
