Seven biogenic amines were extracted from a sample with 6% perchloric acid, then derivatized with benzoyl chloride. 0.02 mol/L borate buffer (pH 9.2) containing 0.06 mol/L sodium deoxycholate-methanol （95∶5, v/v）was used as a running buffer. The detection wavelength was set at 214 nm. The separation was achieved within 12 min. Good linearities were observed from the calibration plots in the concentration ranges.

样品经6%过氯酸萃取后，由苯甲酰氯衍生化，以含0.06 mol/L脱氧胆酸钠的0.02 mol/L硼酸(pH 9.2)-甲醇(体积比为95∶5)混合液为电泳介质，电泳电压25 kV，温度25 ℃，检测波长214 nm，在12 min内实现了7种生物胺的完全分离。7种生物胺的浓度与其峰面积在一定的范围呈良好的线性关系，检出限除组胺为15 μg/g外，其余均为5 μg/g。
