| 英文摘要 | to identify the main, components from three impure samples in gastrodia elata blume, a method of high performance liquid chromatography-electrospray-mass spectrometry-mass spectrometry (hplc/esi/ms/ms) was used. first, three identified p-hydroxyphenylic compounds were analyzed by hplc/esi/ms. molecular ions [m - 1] and other two characteristic ions [m - 1 + 20] and [2m - 1] were clearly observed in their negative electrospray-mass (esi(-)) spectra. according to this rule, the molecular,ions from unknown p-hydroxyphenylic compounds can be easily identified by using the same method. secondly, combining characteristic fragmentary ions obtained by ms/ms spectra and other structural information such as chemical reaction, nuclear magnetic resonance (nmr) and ultraviolet spectra (uv), five compounds from three impure samples in gastrodia elata blume were successfully clarified in which three were the main components from the samples and two others were trace components. so, the method of hplc/esi/ms/ms may be used to identify the structure of main components from impure samples, it can be also used as a guide method for separating. |
