| 摘 要： | 建立了化妆品中7种禁用着色剂的反相高效液相色谱检测方法。试样经乙腈提取后,采用Luna C18(150 mm×2 mm,5μm)色谱柱,以乙腈和4%乙酸铵水溶液为流动相,梯度洗脱,于530 nm波长下紫外检测。7种着色剂的检测低限范围为0.1～0.6μg/mL,回收率为86.67%～98.67%,相对标准偏差为4.11%～7.25%。该方法灵敏度高,可用于化妆品中禁用着色剂检测。

| Abstract: | A method to detect 7 forbidden colorants in cosmetics by high performance liquid chromatography was carried out.The samples were extracted by acetonitrile,isolated by a Luna C18 liquid chromatographic column(150 mm×2 mm,5μm)with acetonitrile 4%CH_3COONH_4 as mobile phase and detected at 530 nm by Ultraviolet-Vis detector.The results indicated that the lowest limit of detection (LOD) were 0.1-0.6 mg/L for 7 forbidden colorants,the average recoveries ranged from 86.67%-98.67%and the relative standard deviation(RSD) were 4.11%-7.25%.This method is highly sensitive for detecting forbidden colorants |
