摘　　要：目的:通过测定不同生长年限和不同采收期玉竹的多糖、总黄酮和总皂苷的含量,确定玉竹的最佳采收时间。方法:应用分光光度法。结果:随着生长年限的增加,长白山玉竹的总多糖、总黄酮和总皂苷含量均呈增加趋势,而总多糖、总黄酮和总皂苷含量在10月11日之后达到最高。结论:长白山玉竹最佳采收年限为6年生,最佳采收期为10月中旬。Objective： The optimum harvesting time of Polygonatum odoratum was determined through determination on total saponins, total flavone and polysaccharide contents of Polygonatum odoratum from different harvesting periods and growth years. Methods： Determining the contents by the spectrum-photometry. Results： The content of symbols increased as the growth years increase. Conclusion： The most suitable time to collect cultivated symbols is during the begin of October when the six years comes.
