摘要: 目的:建立一种可靠的测定番茄及其制品中番茄红素含量的C18-HPLC-PDA方法。色谱条件:固定相为DIAMONSILTM柱(Dikma Technologies,250×4.6mm,5μm);流动相A为乙腈:水(9:1);流动相B为乙酸乙酯;线性梯度洗脱:在15min内,流动相B由0%增为100%(V/V),随后5min,流动相B保持100%;流速1.0ml/min,PDA波长范围260~600nm;色谱图检测波长471nm;进样量20μl;柱温=室温。结果:此方法的定量限为0.10μg/ml,质量浓度在0.10~25.60μg/ml范围内浓度与组分峰面积的线性相关系数为0.9994,RSD为2.6%,回收率为99.3%。结论:这是一种番茄及其制品中番茄红素含量测定的可靠方法。

Abstract: Objective: This study aims to develop a reliable quantitative detection method of lycopene from tomato and processed products by C18-HPLC-PDA. Chromatographic conditions: stationary phase DIAMONSILTM column (Dikma Technologies, 250 ×4.6 mm, 5μm); mobile phase A acetonitrile-water (9:1); mobile phase B ethyl acetate; linear gradient: an increased mobile phase B from 0 to 100% (V/V) in 15 minutes followed by 100% B for 5 minutes; flow rate 1.0 ml/min; PDA wavelength range 260~ 600 nm; monitoring wavelength on chromatogram 471 nm; injection volume 20μl; column temperature: room temperature. Results: Minimum detection limit of this method is 0.10μg/ml. In the range of 0.10~25.60μg/ml, linear correlation coefficient between the concentration and peak area of lycopene fraction 0.9994 RSD 2.6%, recovery 99.3%. Conclusion: This method is reliable to detect lycopene amount from tomato and processed products quantitatively.
