| 抄録: | We succeeded in performing mass spectrometric imaging (MSI) of the localization of ginsenosides (Rb_1, Rb_2 or R_c, and Rf) in cross-sections of the Panax ginseng root at a resolution of 100 μm using matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS). Tandem mass spectrometry (MS/MS) of alkali metal-adducted ginsenoside ions revealed structural information of the corresponding saccharides and agricones. MALDI-MSI confirmed that localization of ginsenosides in the cortex and the periderm is higher than that in the medulla of a lateral root. In addition, it revealed that localization of ginsenosides in a root tip (diameter, 2.7 mm) is higher than that in the center of the root (diameter, 7.3 mm). A quantitative difference was detected between localizations of protopanaxadiol-type ginsenoside (Rb_1、 Rb_2, or R_c) and protopanaxatriol-type ginsenoside (Rf) in the root. This imaging approach is a promising technique for rapid evaluation and identification of medicinal saponins in plant tissues. |
