A combinative method of HPLC fingerprinting and quantitative determination was successfully applied to monitor dynamic accumulation of ginsenosides in five-year-old Panax ginseng roots from different harvest times. The optimal chromatographic conditions were achieved on a C18 column with gradient elution using acetonitrile and 1 mmol · L(-1) KH2PO4 buffer solution at 203 nm. The result indicated that the contents of total ginsenosides showed significant variations, and a decrease tendency… CONTINUE READING
