To determine the optimal harvest time for P. notoginseng through studying the changes of saponin contents with growth periods. 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. Total saponin contents decreased from April through July, and increased from August through December. The optimal harvest time is determined as from October through December, which corresponds to the traditional harvest time.
