ABSTRACT

<p><b>UNLABELLED</b>To study the infected root of Panax quinquefolium on the contents of ginsenosides.</p><p><b>METHOD</b>The 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.</p><p><b>RESULT</b>Rg1 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.</p><p><b>CONCLUSION</b>The 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.</p>
