三七皂苷积累规律的研究

Studies on Saponin Accumulative in Regularities Panax notoginseng (Burk) F. H.Chen

目的 :研究三七皂苷的积累规律 ,为确定三七的最佳采收期提供依据。方法 :定期定点采集三七样品 ,分析三七总皂苷和主要单体皂苷含量。结果 :4～ 7月三七皂苷含量减少 ,8～ 12月 ,三七皂苷含量增加。结论 :10～ 12月为三七最佳采收期 ,与传统确定的采收期相吻合。

Objective:To defermine 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 experiment al 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. [
