1、顶空气相色谱法测定酒石酸罗格列酮原料药中4种有机溶剂残留量朱永琴H,王志远2杨东菁3王雪芹(1.河南省食品药品检验所,郑卅I450003;2.河南大学药学院,河南开封475001;3.河南大学医学院,河南开封475001)中图分类号R927.2文献标志码A文章编号1001—0408(2014)37.3518.03DOI10.6039/j.issn.1001—0408.2014.37.21摘要目的:建立测定酒石酸罗格列酮原料药中4种有机溶剂即甲醇、乙醇、甲苯和Ⅳ,Ⅳ.二甲基甲酰胺(DMF)残留量的方法。方法:采用顶空进样毛细管气相色谱法,以二甲基亚砜为溶剂,色谱柱为INN
2、OWAX毛细管柱,载气为氮气,氢火焰离子化检测器,程序升温;顶空瓶平衡温度为80℃,平衡时间为30min。结果:4种有机溶剂均达到了完全分离;甲醇、乙醇、甲苯、DMF的检测质量浓度线性范围分别为14.72~294.4、24.8~496.0、4.51~90.2、4.62~92.4Ixg/ml(,为O.9991~O.9995);平均回收率分别为97.89%、99.8l%、100.55%、101.06%,RSD分别为1.19%、1.74%、0.84%、1.O9%(n=3);检测限分别为2.944、4.960、O.902、O.924~g/ml。样品中只检出了乙醇,均为O.2%。
3、结论:建立的顶空气相色谱法测定4种有机溶剂残留量,操作简便、结果准确可靠。关键词顶空气相色谱法;酒石酸罗格列酮原料药;有机溶剂;残留量测定Determinationof4ResidualOrganicSolventsinRosiglitazoneTartrateDrugSubstancebyHeadspaceGCZHUYong—qin,WANGZhi—yuan,YANGDong~ing。,WANGXue—qin(1.HenanProvincialInstituteforFoodandDrugControl,Zhengzhou450003,China;2.Pharmace
