摘要
建立HPLC法同时测定旱芹中木犀草素和旱芹素含量的方法。采用C1(8 150 mm×4.6 mm,5μm)柱,流动相为乙腈∶0.01 mol/L醋酸铵(pH=4.8)=40∶60,等强度洗脱,检测波长330 nm,柱温25℃,流速1.0 mL/min。木犀草素和旱芹素的质量浓度分别在0.93μg/mL^4.94μg/mL(r=0.999 1)及1.03μg/mL^5.06μg/mL(r=0.999 4)范围内与峰面积呈现良好的线性关系,平均加样回收率依次为99.7%(RSD为2.4%),99.0%(RSD为1.8%)。
To establish a method for simultaneous determination of Luteolin and Apigenin in Apium graveolen L. by HPLC. The sepration was performed on an C18 column with acetonitrile 0.01 mol/L ammonium acetate （pH=4.8）=60∶40 as a mobile phase at a flow rate of 1.0 mL/min. The detection wavelength was 330 nm at 25℃. There were good linear relationships between the mass concentrations and the peak areas of luteolin and apigenin in the ranges of 0.93μg/mL-4.94μg/mL（r=0.999 1）and 1.03μg/mL-5.06μg/mL （r=0.999 4） respectively. The average recoveries were 99.7%with RSD 2.4%and 99.0%with RSD 1.8%respectively. The method was quick,simple and repeatable for the determination of Luteolin and Apigenin in Apium graveolen L.
