【摘要】 应用番茄红素简便测定方法测定样品中番茄红素的含量,比较不同预处理方法对其含量测定的影响,并对番茄红素标准溶液的稳定性进行了探讨。结果显示:该方法的标准曲线线性范围为0.180～5.796μg/ml,检出限LD=0.0059μg/ml。应用甲醇处理样品,所测得番茄红素含量最高。在室温条件下,24h内番茄红素标准溶液稳定,抗氧化剂BHT对其影响较小。该方法适合于番茄红素含量在0.180～5.796μg/ml范围的样品检测。更多还原

【Abstract】 To assay the contents of lycopene in several samples. The effects of different pretreatments on assay were studied. The linear range of the method is 0.180～5.796μg/ml, with LD=0.0059μg/ml. Analysis showed that the methanol treatment is favorable for assay so that within 24 hours, the lycopene solution is stable. The results thas showed that this method is favorable for assaying the contents of lycopene in tomato and tomato products.更多还原
