摘要(Abstract):

通过建立川白芷中欧前胡素、异欧前胡素、氧化前胡素的"一测多评"含量测定方法,实验只用一个对照品同步测定川白芷中的3个成分。以欧前胡素对照品为内标物,在线性范围内,采用HPLC-DAD建立其与异欧前胡素、氧化前胡素的相对校正因子,并用该校正因子进行异欧前胡素、氧化前胡素的含量计算,实现"一测多评";同时采用外标法测定药材中这3种香豆素的含量,并比较计算值与实测值的差异。结果 20批药材中3种香豆素含量的计算值与实测值无显著差异(RSD<5%)。研究结果表明"一测多评"法控制川白芷药材的质量是可行、准确的。
Objective: To develop a quantitative analysis of multi-components by single marker(QAMS) method for simultaneous determination of three coumarins in Angelica dahurica var.formosana,by using one standard substance.Method: With imperatorin as internal reference standard,and 2 relative correction factors(RCF) to imperatorin were calculated within certain ranges.Their contents in 20 batches of samples,collected from different areas,were determined by both external standard method and QAMS.The method was evaluated by comparison of the quantitative results between the two methods.Result: No significant differences were found in the quantitative results of three coumarins in 20 batches of A.dahurica var.formosana determined by the two methods(RSD<5%).Conclusion: QAMS is feasible and suitable for quality control of A.dahurica var.formosana.
