Exploration of tissue distribution of ginsenoside Rg1 by LC-MS/MS and nanospray desorption electrospray ionization mass spectrometry

Ginsenoside Rg1 (Rg1) was one of the dominent active components in several Panax medicinal species as Panax notoginseng and Panaxginseng with diversified bioactivities. However, the study on tissue distribution of Rg1 remained limited and needed to be further explored for elucidation of its spatial distribution. In the present study, a LC–MS/MS combined with nanospray desorption electrospray ionization (DESI) mass spectrometry method was...
