摘要
利用电喷雾串联质谱 (ESI MS MS)对雪上一支蒿的乙醇提取液进行了直接分析 ,方法简便 ,直观 ,用样量少。ESI MS可以给出分子量信息 ,MS MS方法则可以从复杂体系中获得结构信息。在雪上一支蒿中发现乌头碱、去氧乌头碱及它们的水解产物和脂类生物碱等共 1 9种二萜生物碱 。
A rapid method was applied to analyze the ethanol extract of the roots of aconitum brachypodum, by using electrospray ionization tandem mass spectrometry (ESI-MS/MS) directly. The information of molecular weight and the furthermore information of structure were obtained from the complex system by ESI-MS/MS. 19 kinds of Aconitum alkaloids including aconitine, deoxyaconitine, the hydrolysis products of them and lipo-alkaloids were found, in which lipo-alkaloids are firstly reported in this particular plant.
