Abstract:

The saponins of Sapindus mukurossi was analyzed by tandem mass spectrometry. The molecular weights of 12 saponins from the total saponin of S. mukurossi were determined by positive and negative ions ESI-MS and their molecular formula were acquired by HR-ESI-MS. Furthermore, the four hederagenin saponins and seven acyclic sesquiterpene saponins were identified based on the tandem mass spectrometry.

Key words: Sapindus mukurossi; Hederagenin saponin; Sesquiterpene oligoglycoside; Tandem mass spectrometry
