ANALYSIS OF GYNZENOSIDES IN THE ROOTS OF PANAX GINSENG INTRODUCED IN THE CENTRAL BOTANICAL GARDEN OF NAS OF BELARUS

For the first time, a detailed study of the qualitative and quantitative composition of ginsenosides in the Panax ginseng roots was carried out with the help of high-performance liquid chromatography combined with mass spectrometry (HPLC-MS). The plants were introduced into the conditions of the Republic of Belarus at the experimental plot of the Central Botanical Garden of the National Academy of Sciences of Belarus. It was found that in the examined roots, all basic neutral glycosides of ginseng (ginsenosides Rb1, Rc, Rb2/Rb3, Rd, Rf, Rg1 and Re), as well as their malonylated derivatives (malonylginsenosides Rb1, Rc, Rb2/Rb3, Rd, Rg1 and Re) and some “minor” ginsenosides (20-gluco-ginsenoside Rf, notoginsenosides R1 and R2, isomers of malonyl-ginsenosides Rb1 and Rd) are present. The research also showed that different parts of the P. ginseng roots differ significantly in a total content of ginsenosides: for the main root, this parameter was 3.3 % of dry mass, and for the lateral roots – 7.8 % of dry mass.
