【Abstract】 Objective To determine the content of quercetin in Jiangzhi Qingsh en tea with RP-HPLC,to provide the evidence for the quality control.Methods Diamo nsil TM (diamond) C18 column (250 mm×4.6 mm,5 μm) was used.Mobile phase was ca rbinol-water-phosphoric acid (55 ∶45 ∶0.2);flow rate was 0.9 mL/min.Detectio n wavelength was 254 nm.Results Quercetin presented a good linear relation with the peak area in the range of 0.05-1.0 μg.The average recovery rate was 96.2%,RSD=1.88%(n=5).Conclusion This method... 更多还原 【关键词】 槲皮素; 高效液相色谱法; 含量测定; 【Key words】 quercetin; HPLC; content determination;
