| 摘 要： | 建立高效液相色谱法检测奶粉中雌二醇的方法。优化实验条件,采用紫外检测器,检测波长为230 nm。方法对奶粉中雌二醇的检出限为5 ng/g。在低、中、高3个加标水平下,奶粉中雌二醇的回收率在81.0%～91.9%的范围内,相对标准偏差在3.71%～4.74%范围内(n=4)。该法可有效监控奶粉中雌二醇的残留量。

| Abstract: | A method was developed with high performance liquid chromatography(HPLC) to detect estradiol in milk powder.The conditions of chromatography were optimized,ultraviolet spectrometry was used and detection wavelength was 230 nm.The detection limits were 5 ng/g.On the low,middle and high concentration level,the recoveries were 81.0 %-91.9 %,the relative standard deviations(RSD) were 3.71 %-4.74 %(n=4).The method could be used to detect estradiol residue in milk powder. |
