摘要(Abstract):

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%);610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<1 mm(0.5110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<1 mm(0.510.60 cm)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.
