摘 要:A method was developed to determine acacetin, luteolin and quercetin in Chrysanthem indicum L by β-CD modifiedcapillary electrophoresis. Through the investigation of the effects of buffer pH and concentration, applied voltage, SDS concentration andβ-CD, the analytical conditions were optimized. Under the optimized conditions, the two analytes were well separated in 8 min. A goodlinear relationship between the peak area and concentration was found in the 2-400μg/mL,2-500 μg/mL and 2-500μg/mLconcentration range for acacetin, luteolin and quercetin, respectively. The relative standard deviation based on migration time and peakarea were 0.51%, 0.76%, 0.83% and 2.17%, 2.42%, 2.68% for acacetin, luteolin and quercetin, respectively. The detection limits basedon three time noise were 0.6μg/mL, 0.5μg/mL and 0.6μg/mL for acacetin, luteolin and quercetin, respectively. The method wasverified by real sample analysis and running standard addition and recovery experiments with satisfactory results.A method was developed to determine acacetin, luteolin and quercetin in Chrysanthem indicum L by β-CD modifiedcapillary electrophoresis.
