目的:建立人参提取物中农药残留-腐霉利的HPLC含量测定方法。方法:BDS HYPERSIL C18分析色谱柱(4.6 mm×250 mm,5μm),流动相乙腈-水(40∶60),流速1.0 mL·min-1,检测波长220 nm。结果:腐霉利进样量0.001~0.6μg与色谱峰面积呈良好线性关系(R2=0.999 4),平均加样回收率100.0%(n=9),RSD 3.0%。结论:该法简便、准确、可靠,可用于人参提取物中腐霉利残留的含量测定。
Objective: To establish a method for the determination of pesticide residues in Pyrenophora by HPLC method. METHODS: BDS HYPERSIL C18 column (4.6 mm × 250 mm, 5 μm) was used. The mobile phase was acetonitrile-water (40:60) at a flow rate of 1.0 mL · min-1. The detection wavelength was 220 nm. Results: There was a good linearity (R2 = 0.999 4) between the range of 0.001 ~ 0.6 μg and the peak area of the samples. The average recoveries were 100.0% (n = 9) and 3.0% RSD. Conclusion: The method is simple, accurate and reliable, and can be used for the determination of the residues of the genistra in ginseng extract.
