摘 要:目的建立高效液相色谱法测定压片糖果和固体饮料中2种新型卡巴地那非类似物的方法。方法样品经甲醇超声提取,提取液离心、过微孔滤膜后上机分析。采用Waters Xbridge C_(18)色谱柱(250 mm×4.6 mm,5μm)分离,以20 mmol/L乙酸铵水溶液和甲醇为流动相进行梯度洗脱,外标法定量测定。结果在0.5~100.0μg/mL的范围内2种新型卡巴地那非类似物线性关系良好(r^(2)>0.999),定量限均为5 mg/kg。2种新型卡巴地那非类似物于1、2、10倍定量限3个水平下的平均回收率范围为87.32%~93.92%,相对标准偏差为1.19%~4.08%。采用该方法共检出8批次阳性样品,含量范围为218~2170 mg/kg。结论该方法操作简便,准确可靠,满足压片糖果和固体饮料中非法添加2种新型卡巴地那非类似物的含量测定,为打击食品中非法添加新型那非类物质提供可行的技术手段。Objective To establish a method for determination of 2 kinds of new carbadenafil analogue in tablet candies and solid beverages by high performance liquid chromatography.Methods The sample was extracted by methanol ultrasound,the extract was centrifuged,filtered through a microporous membrane,and analyzed by the high performance liquid chromatography.The separation was performed on a Waters Xbridge C_(18) column(250 mm×4.6 mm,5μm)with gradient elution by using 20 mmol/L ammonium acetate aqueous solution and methanol as the mobile phase,and quantified by external standard method.Results The 2 kinds of new carbadenafil analogue demonstrated good linearity in the range of 0.5-100.0μg/mL,with the correlation coefficient values(r^(2))being higher than 0.999.The limits of quantification were found to be 5 mg/kg.The recoveries at 3 spiked levels of 1,2 and 10 times the limits of quantification in blank matrix were in the range of 87.32%-93.92%,with the relative standard deviations between 1.19%-4.08%.A total of 8 batches of positive samples were detected using this method,with a content range of 218-2170 mg/kg.Conclusion The method is convenient,accurate and efficient.It can meet the identification requirement of illegally added 2 kinds of new carbadenafil analogue in tablet candies and solid beverages,and provide effective technical support to combat the illegal addition of new carbadenafil analogue in food.
