Abstract

The roots of Panax ginseng C. A. Meyer contain a relatively high percentage of ginsenosides from their first year of life onwards. Since the major development of weight of roots occurs between the 4th and 5th year of life, it has been established that the highest yield of ginsenosides and therefore the best time for harvesting the roots is at the end of the summer of the 5th year.
