摘　　要：建立了测定纸品中卡拉花醛含量的气相色谱／串联质谱分析方法，纸品中的卡拉花醛经超声萃取后，进行气相色谱／串联质谱法分析，外标法定量。在信噪比（S／N）为10的条件下，方法定量下限为0．10mg／kg。方法的加标平均回收率为88．73％-94．61％，相对标准偏差为3．91％-7．94％。该方法快速简便，定性可靠，定量准确，适用于纸品中卡拉花醛的日常分析检测。A gas chromatography/tandem mass spectrometry（GC/MS-MS） method was established for the determination of karanal in paper products. Karanal in paper products was first ultrasonically extracted, and then analyzed by GC/ MS-MS. The concentration of karanal was quantified by the external standard method. The limit of quantification （LOQ） was 0.10 mg/kg at signal to noise（S/N） of 10. The spiked average recoveries changed from 88.73% to 94.61% under 3 spiked levels while the relative standard deviation（RSD） changed from 3.91% to 7.94%. The proposed method was simple, sensitive, accurate and convenient to operate, and appropriate to the routine analysis of karanal in paper products.
