Abstract:
UNLABELLEDTo study the infected root of Panax quinquefolium on the contents of ginsenosides.
METHODThe contents of three major ginsenosides Rg1, Re and Rb1 were determined by HPLC compared quantitatively between the different degree infected roots and normal root in the phloem and xylem.
RESULTRg1 in phloem and xylem of varying degrees infected root showed no significant difference, but Rb1 decreased 26.3% and 28.3% respectively in medium and serious infected roots comparing to normal root. Re in phloem of seriously infected roots decreased in xylem significantly.
CONCLUSIONThe results indicate that the variation of ginsenosides in different degrees infected roots exists and the proportion of Rg1, Re and Rb1 in the total ginsenosides changes.
