安徽农学通报2023年03期畜禽·水产·饲料·兽药HPLC法测定安痛定注射液3种组分的含量丁阳冯超林陈向丹董书香王峻*(湖北省兽药监察所,湖北武汉430070)摘要本文建立了安痛定注射液中巴比妥、安替比林、氨基比林含量的HPLC测定方法:采用AgilentEclipsePlusC18色谱柱(4.6mm×250mm,5µm),流动相为乙腈-磷酸盐缓冲液(pH7.8~8.0)(20∶80)(用磷酸调节pH至8.0),检测波长240nm,流速1.0mL/min。结果表明,巴比妥在4.5~67.5µg/mL的浓度范围内呈线性关系,r=0.9997,平均回收率96.2%;安替比林在10~150µg/mL的浓度范围内呈线性关系,r=0.9999,平均回收率100.1%;氨基比林在25~375µg/mL的浓度范围内呈线性关系,r=0.9999,平均回收率97.1%;该方法简便、准确、快速、重现性好,可用于该制剂的含量测定。关键词安痛定注射液;含量测定;HPLC中图分类号O657.72文献标识码A文章编号1007-7731(2023)03-0092-03DeterminationofThreeComponentsinAntondineInjectionbyHPLCMethodDINGYangFENGChaolinCHENXiangdanDONGShuxiangWANGJun*(HubeiProvincialInstituteofVeterinaryDrugSupervision,WuhanHubei430070)AbstractAmethodforthedeterminationofBarbital,PhenazoneandAminophenazoneinAntondineInjectionbyHPLCwasestablished.TheexperimentusedAgilentEclipsePlusC18column(4.6mm×250mm,5µm),acetonitrile-phosphatebuffer(pH7.8-8.0)(20∶80)(thepHvaluewasadjustedto8.0withphosphoricacid)asthemobilephase,thedetectionwavelengthwas240nmwiththeflowrateof1.0mL/min.ResultsshowedthatlinearrangeofBarbitalwas4.5-67.5µg/mLwithrof0.9997,averagerecoverywas96.2%.LinearrangeofPhenazonewas10-150µg/mLwithrof0.9999,averagerecoverywas100.1%.LinearrangeofAminophenazonewas25-375µg/mLwithrof0.9999,averagerecoverywas97.1%.Themethodissimple,accurate,rapidandreproducible,andcanbeusedforthecontentdeterminationofthepreparation.Keywordsantondineinjection;contentdetermination;HPLC安痛定注射液是广泛应用的解热镇痛药,含巴比妥、安替比林和氨基比林3种成分。《中国兽药典》2015年版一部均采用高效液相色谱法及容量分析进行含量测定[1],此方法操作烦琐费时,误差较大。笔者参考相关文献[2-4],采用高效液相色谱法同时测定巴比妥、安替比林和氨基比林的含量,该方法具有简易、快速、高效、重复性好...
