摘要:

目的:建立连翘中7个活性成分的含量测定方法。方法:对UPLC色谱参数进行优化,建立一测多评分析方法,并对该方法的线性范围、回收率、精密度、稳定性、重复性进行考察。结果:选用乙腈-0.1%磷酸水作为流动相,以277 nm作为检测波长,最佳柱温为30 ℃,最佳流速为0.3 mL/min。绿原酸、咖啡酸、芦丁、金丝桃苷、连翘酯苷A、连翘苷和牛蒡子苷元分别在0.009 80~0.196 00 μg(r=0.998 4),0.008 96~0.179 20 μg(r=0.998 9),0.008 00~0.240 00 μg(r=0.999 4),0.009 16~0.183 20 μg(r=0.999 2),0.020 72~0.414 40 μg(r=0.999 5),0.019 82~0.396 40 μg(r=0.999 1),0.006 96~0.139 20 μg(r=0.999 2)范围内线性关系良好,平均加样回收率分别为95.4%(RSD=3.78%),96.3%(RSD=4.61%),97.2%(RSD=4.04%),102.6%(RSD=3.91%),103.7%(RSD=2.37%),98.5%(RSD=1.99%),95.1%(RSD=4.58%)。结论:建立了连翘中7个活性成分含量测定的一测多评分析方法,具有较好的灵敏性和准确性。

Abstract:

Objective: To establish a method to determine the content of seven bioactive components in Forsythia suspensa. Methods: The chromatographic parameters of UPLC were optimized. A QMAS analytical method was built, with its linear range, recovery rate, precision, stability and repeatability evaluated. Results: The mobile phase consisted of 0.1% phosphoric acid solution andacetonitrile.Thedetectionwavelengthwas277nm.Theoptimumcolumntemperaturewas30℃and the optimum speed was0.3mL/min. Chlorogenic acid, caffeic acid, rutin, hyperoside, forsythoside A, phillyrin and arctigenin showed good linear relationships within the ranges of 0.009 80~0.196 00 μg(r=0.998 4), 0.008 96~0.179 20 μg(r=0.998 9), 0.008 00~0.240 00 μg(r=0.999 4), 0.009 16~0.183 20 μg(r=0.999 2), 0.020 72~0.414 40 μg(r=0.999 5), 0.019 82~0.396 40 μg(r=0.999 1), 0.006 96~0.139 20 μg(r=0.999 2), and the average recoveries were 95.4%(RSD=3.78%), 96.3%(RSD=4.61%), 97.2%(RSD=4.04%), 102.6%(RSD=3.91%), 103.7%(RSD=2.37%), 98.5%(RSD=1.99%), 95.1%(RSD=4.58%), respectively. Conclusion: A QMAS analytical method for seven bioactive components in Forsythia suspensa has been established, which has a high sensitivity and accuracy.
