摘要：

Molecular weight of 8 ginsenosides and the component of total saponions in American ginseng have been determined by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS). The average error of the molecular weight of each ginsenoside was found less than 0.05%. The results demonstrate that MALDI-MS is a very simple and useful method to measure the molecular weight of some high polar, thermal unstable small molecules with high sensitivity and reproducibility.
