摘要:

为建立一种在C30-HPLC 上使用外标法对番茄红素全反式异构体进行定量检测的方法,采用色谱条件:固定相:YMC Carotenoid columu C30 色谱柱(4.6mm × 250mm,SOD-5μm,Waters);流动相A:乙腈- 甲醇(3:1,V/V);流动相B:甲基叔丁基醚(MTBE);流动相A 与B 中分别添加0.05%(V/V)的三乙胺;线性梯度洗脱:B 在20min 内由0 增至80%,20~35min 内B 维持在80%;流速:1mL/min;色谱图检测波长470nm;进样量:20μL;柱温:室温。结果表明:此方法的最小定量限为0.10μg/mL,在10~100μg/mL 范围内质量浓度与组分峰面积的线性回归方程为y=212181x,R2=0.9738。相对标准偏差为4.04%。外标加样回收率为97.34%(RSD 为0.904%)。应用本方法可对番茄果实中的全反式番茄红素进行定量分析。

Abstract:

An external standard method was established to determine all-trans-lycopene on C30-HPLC. Stationary phase was YMCTM Carotenoid column C30 (4.6 mm × 250 mm, SOD-5μm, Waters); mobile phase A was acetonitrile-methanol (3:1, V/V); mobile phase B was methyl tert-butyl ether (MTBE); both mobile phase A and B were added 0.05% (V/V) triethylamine; linear gradient elution was conducted with an increase of mobile phase B from 0 to 80% (V/V) in 20 min followed by maintaining at 80% mobile phase B for 15 min; flow rate was 1.0 mL/min; monitoring wavelength was 470 nm; injection volume was 20μL; column temperature was set at room temperature. Under these determination parameters, the minimum detection limit was 0.10μg/mL; in the range of 10 100μg/mL, linear correlation equation was y = 212181x (R2 = 0.9738) with a RSD of 4.04%. The recovery rate of external standard was 97.34% with a RSD of 0.904%. Therefore, this established method is suitable for determining alltrans-lycopene in tomato fruits.
