Abstract: 目的 建立气相色谱法测定吡喹酮及片剂中的四种残留溶剂.方法 采用DB-624(30 m×0.5 mm,0.5 μm)色谱柱,柱温箱程序升温,采用FID检测器对乙醇和乙酸乙酯进行检测,采用ECD检测器对三氯甲烷和二氯甲烷进行检测.结果 乙醇、乙酸乙酯、三氯甲烷、二氯甲烷四种残留溶剂分别在0.051 0~5.102 4mg·mL-1,0.050 0 ~4.995 0 mg·mL-1,0.515 8 ~51.58 μg·mL-1,5.0080~500.8 μg· mL-1范围内呈良好的线性关系,相关系数均大于0.999 5.结论 建立的气相色谱法简单、快速、准确,可用于吡喹酮原料及其制剂中的残留溶剂的检测,为国家评价性抽验工作提供技术支持.
