Abstract

OBJECTIVE: To provide the proof for the quality evaluate and the utilization of root rot Panax notoginseng, the contents of saponins were analyzed, such as ginsenoside Rb1, ginsenoside Rg1 and notoginsenoside R1 in the rotted and normal roots. METHOD: The saponin contents were contrasted with samples in same field and different rotted degree Panax notoginseng. The single saponin was determined by HPLC and the total saponin was determined by macro resin absorbing-colorimetric method. RESULT: The total saponin was decreased 30.88% in sick root than in normal root. The contents of three single saponin R1, Rg1, Rb1 were decreased 25.53%, 11.26% and 17.82%, respectively. CONCLUSION: The saponin contents was declined with the degree of rot. The rot had no effect on the proportion of the three single saponin.
