Determination of trace pyrraline in food samples using solidphase extraction and high performance liquid chromatography

A solid phase extraction- high performance liquid chromatography for determination of pyrraline in food was established. Pyrraline was extracted from food material by a HLB- SPE column and analyzed by high performance liquid chromatography.Results showed that a good linear range from 5 × 10~(-7) to 2 × 10~(-3)mol / L with correlation coefficient of 0.9999 was obtained. The relative standard deviation were 0.78% ～ 7.51%.The limit of detection was 5 × 10~(-7) mol / L( S / N = 3).The discussed method was simple and accurate and could be applied to the detection of trace pyrraline in food.
