摘　　要：目的:分析河南、浙江、陕西3个产区山茱萸中主要化学物质的积累规律,确定最佳采收期。方法:分别对山茱萸样品中的熊果酸、马钱苷、鞣质、多糖、总有机酸的含量以及醇浸物、水浸物等指标进行测定,对测定结果进行主成分分析。结果:3个产区不同生长期的山茱萸中主要化学物质积累都具有一定的规律;山茱萸果树生长年限对药材质量影响不大;果树的大小年现象对药材质量影响也不明显。结合当地的传统采收习惯,确定河南、浙江两产区最佳采收期为10月下旬,陕西产区为10月中旬。结论:研究结果为山茱萸传统采收期提供了科学依据。Objective： To analysis accumulation rule of major chemical substances of Corni Fructus in three production areas of Henan, Zhejiang and Shanxi to determine the best harvest time. Methods： Determining and analysing the content of ursolic acid, loganin, tannin, polysaccharide, total organic acids, water-soluble extract and ethanol-soluble extract of Corni Fructus samples. Results： There is a certain accumulation rule of major chemical substances of Corni Fructus in different growth period from three production areas. The growth age of Corni Fructus has little effect on the quality of medicines ; good harvest or yield reduction of Corni Fructus has not obvious influence on the quality of medicines, too. Considering the local harvest habits traditionally, it approved that the best harvest period of Henan and Zhejiang is in late October and the best harvest of Shanxi is the mid of October. Conclusion： This result provides a scientific basis for the traditional harvest period of Corni Fructus.
