The contents of rutin and quercetin were first determined by High Performance Liquid Chromatography (HPLC) in 368nm and analyzed on the C18 column by a isocratic elution, using a mixture of methanol-phosphoric acid solution(58:42, V/V) as the mobile phase with a flow rate of 1.0mL/min. The method is calibrated by an external standard method. Under the optimal conditions, the correlation coefficient of rutin and quercetin in the concentration range of 0.1~200mg/L is more than 0.999. The average recovery rates of rutin and quercetin in the spiked range of 2.0~100mg/kg are 83.5%~94.2% and 84.8%~91.2%, respectively. And the relative standard deviations are 2.9%~7.4% and 4.2%~6.9%, respectively (n=6). Using the automated pressurized liquid extractor method, the detection limit (LOD) of rutin and quercetin are 0.05mg/kg and 0.03mg/kg, respectively, and the quantitative limits (LOQ) of rutin and quercetin are 0.2mg/kg and 0.1mg/kg, respectively. Therefore, the method developed for the determination of rutin and quercetin in onion by automated pressurized liquid extractor and high performance liquid chromatography gives a good linearity, repeatability and high sensitivity, and is suitable for the rapid determination of rutin and quercetin in vegetables and fruits., authors=null, authorsList=null, authorCompany=null,

articleAbstract=通过与水浴回流法比较，建立了全自动加压溶剂萃取法，可简单、快速测定洋葱中保健活性物质芦丁和槲皮素含量。采用高效液相色谱仪在368nm波长处测定芦丁和槲皮素含量。色谱柱为C18柱，流动相为甲醇-磷酸溶液（58:42，体积比），以1.0ml/min流速等度洗脱，外标法定量。结果表明，在芦丁和槲皮素质量浓度为0.1~200mg/L时，其线性相关系数均大于0.999。在2.0~100mg/kg的添加水平下，芦丁和槲皮素的平均回收率分别为83.5%~94.2%和84.8%~91.2%；相对标准偏差分别为2.9%~7.4%和4.2%~6.9%（n=6）。全自动加压溶剂萃取法的检出限（LOD），芦丁和槲皮素分别为0.05，0.03mg/kg。定量限（LOQ），芦丁和槲皮素分别为0.2，0.1mg/kg。研究建立的运用全自动加压溶剂萃取仪提取、高效液相色谱测定洋葱中芦丁和槲皮素的方法，线性良好，重现性较好，灵敏度较高，能够满足蔬菜和水果等农产品中芦丁和槲皮素的快速检测。,
