Abstract
Objective:
To determine the optimal harvest time for P. notoginseng through studying the changes of saponin contents with growth periods.
Methods:
P. notoginseng samples were collected from the experimental plot regularly, and then the contents of total saponin and some main single saponins were analyzed by HPLC.
Results:
Total saponin contents decreased from April through July, and increased from August through December.
Conclusion:
The optimal harvest time is determined as from October through December, which corresponds to the traditional harvest time.
