目的：对纸质食品包装材料中松香酸抽提方案进行优化。方法分别采用超声萃取法、微波萃取法、索氏萃取法、NaOH/尿素/硫脲混合碱溶液溶解-超声提取法对纸质食品包装材料中的松香酸进行提取，并对提取产物进行了高效液相色谱法分析，比较4种提取方法的提取效果，并对经4种提取方法提取后的样品进行了电子显微镜分析，观察提取后的样品中松香的残留情况。结果经混合碱溶液-超声提取法处理的样品，松香酸含量测定值明显高于其他三种方法。经超声萃取法、微波萃取法和索氏萃取法处理的样品中均残留有松香，而经混合碱溶液-超声提取法处理的样品中未观察到松香残留，与高效液相色谱分析的结果一致。结论 NaOH/尿素/硫脲混合碱溶液溶解-超声提取法可以完全提取样品中的松香酸。

Objective To optimize the extraction method for abietic acid in paper packaging materials in-tended tocome into contact with foodstuffs.MethodsAbietic acid in paper packaging materials intended to come into contact with foodstuffs were extracted by ultrasonic extraction technique, microwave-assisted ex-traction technique, Soxhet extraction technique and sodium hydroxide/urea/thiourea mixed solution-ultrasonic extraction technique, respectively. The extracts were analyzed by high performance liquid chromatography (HPLC). The extraction effects were compared. The extracted samples were all observed by scanning electron microscope (SEM) in order to search residual rosin.Results The detected value of abietic acid obtained by sodium hydroxide/urea/thiourea mixed solution-ultrasonic extraction technique was much higher than those obtained by ultrasonic extraction technique, microwave-assisted extraction and Soxhet extraction technique. Residual rosin was observed in the samples treated by ultrasonic extraction technique, microwave-assisted ex-traction technique and Soxhet extraction technique but no residual abietic acid was observed in the sample treated by sodium hydroxide/urea/thiourea mixed solution-ultrasonic extraction technique. This result con-firmed the results of HPLC analysis.ConclusionAbietic acid in paper packaging materials intended to come into contact with foodstuffs could be extracted completely by sodium hydroxide/urea/thiourea mixed solution -ultrasonic extraction technique.
