This study was conducted to investigate the difference of general feature and ginsenoside content of 6 years old ginseng rooot among different grade of roots.
Total weight of a 1st grade-6 years old ginseng root was 115.1g and weight, length, diameter and specific gravity of main root were 64.68g, 8.39cm, 3.31cm and 0.96, respectively.
Main root of 1st grade ginseng root was larger in size and specific gravity and more heavy than that of 2nd or 3rd grade of the roots.
Though crude saponin contents were not so different among the different grade of roots, but ginsenoside Rbl, Rgl and Re content were higher in 1st grade of root than that of 2nd or 3rd grade of root. Those ginsenosides were located mainly in periderm and cortex.
