摘 要:目的:建立同时测定桑椹中新绿原酸、绿原酸、芦丁和异槲皮苷4种有效成分含量的准确、精密的高效液相色谱方法。方法:实验中采用Syncronis a Q-C18(Thermo scientific;4.6 mm×250 mm,5μm)色谱柱,乙腈-0.1%甲酸水作流动相,梯度洗脱,流速1 m L·min-1,检测波长350 nm。结果:新绿原酸、绿原酸、芦丁和异槲皮苷在质量浓度分别为0.00106~0.0424 mg/m L,0.00794~0.318 mg/m L,0.00214~0.0856 mg/m L,0.00136~0.0544 mg/m L范围内与峰面积呈良好的线性关系(r〉0.9996);4种有效成分的平均回收率分别为97.7%,99.4%,97.4%,100.4%,RSD分别为1.39%,2.09%,0.62%,1.62%。结论:该方法简便、准确,分离效果好,可用于桑椹的质量评价。Objective: To establish an accurate and reliable analytical method for the simultaneous determination of four active components(neochlorogenic acid,chlorogenic acid,rutin and isoquercitrin) in Fructus Mori. Methods: Neochlorogenic acid,chlorogenic acid,rutin and isoquercitrin in the samples were isolated by gradual elution with acetonitrile-0. 1% formic acid solution and detected by HPLC. The chromatographic condictions: Syncronisa Q-C18(Thermo scientific,4. 6 mm × 250 mm,5 μm) column,flowing rate being 1 m L·min-1,detecting wavelength at 350 nm. Results: Good linearities of neochlorogenic acid,chlorogenic acid,rutin and isoquercitrin were in the range of 0. 00106-0. 0424 mg/m L,0. 00794-0. 318 mg/m L,0. 00214-0. 0856 mg/m L,0. 00136-0. 0544 mg/m L,respectively(r 0. 9996). The average recoveries of the four components were 97. 7%,99. 4%,97. 4% and 100. 4%. The relative standard deviation was 1. 39%,2. 09%,0. 62% and 1. 62%. Conclusion: The method is simple,feasible and reproducible and can be used for the quality control of Fructus Mori.
