摘　　要：目的：探讨多伦野生芍药芍药苷含量动态变化。方法：定株、定时原产地多样本采样，用HPLC测定芍药苷含量，数据经统计分析。结果：5月（苗期）采集的多伦野生芍药芍药苷质量分数平均值最低（3．05％），8，9月（幼果期和果期）采集的含量较高（4．72％，4．58％）；6—10月平均含量之间没有显著差别。野生芍药个体差异很大，当根直径范围〈1mm（0．51—0．60cm）时，芍药苷含量变异系数可达47．17％。结论：野生芍药显蕾以后至枯萎前均可采挖，农闲采挖的现实情况是可行的。首次报告和提出野生芍药株间芍药苷含量差异很大，取样不当，植株个体差异可能影响芍药苷动态变化测定结果。To explore the dynamic change of paeoniflorin content in root of Paeonia lactiflora. Method ： The samples were collected and paeoniflorin content was determined by HPLC. Result： The results showed that the average content of paeoniflorin was the lowest at 3.05% in the roots collected in May, and during the fruit time it was rather high in August at 4.72% , and in September at 4.58%. The average content showed no significant differences during June to October. Conclusion： Wild plant of P. lactiflora might be collected for medical use during blooming stage until wilting stage.
