英文摘要: The quantitation of ginsenoside Rg(3) by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) was investigated. The selection of internal reference was described. The linear regression coefficient of calibration curve was 0.938 and the average relative error was 28.6% if raffinose was added as internal reference, while the linear regression coefficient of calibration curve was 0.993 and the average relative error was 7.5% if rutin was added as internal reference. In addition, the precision was improved when resolution was enhanced and relative peak integral stood for concentration of Rg(3).
