摘要
目的建立新疆两种洋甘菊中木犀草苷、芹苷元-7-葡萄糖苷、7-甲氧基香豆素、木犀草素、芹菜素的一测多评含量测定方法。方法采用超高效液相色谱法,以芹菜素为内标物,建立其与木犀草苷、芹苷元-7-葡萄糖苷、7-甲氧基香豆素、木犀草素的相对校正因子,并进行含量测定,实现一测多评。同时采用外标法测定11批洋甘菊中木犀草苷、芹苷元-7-葡萄糖苷、7-甲氧基香豆素、木犀草素、芹菜素的含量,验证一测多评法的准确性。结果外标测定法5种化学成分在标准曲线范围内均呈良好线性关系(r>0.999 3);平均加样回收率分别为:木犀草苷99.7%、芹苷元-7-葡萄糖苷97.5%、7-甲氧基香豆素98.8%、木犀草素100.9%、芹菜素99.1%,RSD分别为1.8%,0.6%,0.5%,1.8%,1.9%。一测多评法中芹苷元-7-葡萄糖苷、木犀草苷、7-甲氧基香豆素、木犀草素相对芹菜素对照品的校正因子f分别为1.441,2.308,1.117,1.490,RSD分别为0.07%,0.04%,0.09%,0.18%。采用一测多评法计算的含量值与外标法实测值之间无显著差异。结论在对照品缺乏、昂贵的情况下,以外标法测定芹菜素,利用相对校正因子实现对木犀草苷、芹苷元-7-葡萄糖苷、7-甲氧基香豆素、木犀草素的含量测定可行。
Objective To establish a method of simultaneously quantitative analysis for multi-components by single marker（ QAMS） of galuteolin,apigenin-7-glucoside,7-methoxycoumarin,luteolin and apigenin in two species of Chamomiles from Xinjiang. Methods By using apigenin as the internal standard,the relative correction factors（ RCF） of galuteolin,apigenin-7-glucoside,7-methoxycoumarin and luteolin were set and determined by UPLC. The contents of galuteolin,apigenin-7-glucoside,7-methoxycoumarin,luteolin and apigenin in 11 samples of Chamomiles were authentically determined by the external standard method,to verify the accuracy of QAMS. Results There is a good linear relationship within the range of standard curve for five compounds by the external standard method（ r〉 0. 999 3）; the average recovery was 99. 7%,97. 5,98. 8%,100. 9%,99. 1%,for galuteolin,apigenin-7-glucoside,7-methoxycoumarin,luteolin and apigenin,respectively,with RSD as 1. 8%,0. 6%,0. 5%,1. 8% and 1. 9%,respectively. The RCF for pigenin-7-glucoside,galuteolin,7-methoxycoumarin and luteolin to apigenin was 1.441,2. 308,1. 117,1. 490,respectively,with RSD as 0. 07%,0. 04%,0. 09% and 0. 18%,respectively. No significant difference between the quantitative results by QAMS and external standard method was observed. Conclusion It is practical to determine content of galuteolin,apigenin-7-glucoside,7-methoxycoumarin,luteolin with RCF and apigenin by using external standard method,for the deficiency and expensive of the standard reference.
