1、2013年6月中成药June2013第35卷第6期ChineseTraditionalPatentMedicineVo1.35No.6[质量]贴敷后祖师麻膏药中祖师麻甲素和7一羟基香豆素的残留量测定李爽,石晓峰,范彬,白朝辉(1.甘肃中医学院,甘肃兰州I730030;2.甘肃省医学科学研究院,甘肃兰州730050)摘要:目的建立以高效液相色谱法测定祖师麻膏药中祖师麻甲素和7-羟基香豆素的方法,并用于贴敷后祖师麻膏药中药物残留量测定。方法Agi!entEclipsePlusC。色谱柱(4.6mill×250mIi1,5m);流动相
2、为乙腈一0.1%磷酸水溶液(15:85);体积流量为1.0mL/min;检测波长327Bin。6名健康志愿者签署知情同意书后分别在背部贴敷祖师麻膏药3贴,于24、48、72h各揭帖1张,采用上述方法测定其祖师麻甲素和7一羟基香豆素的残留量,进而计算残留率。结果祖师麻甲素、7一羟基香豆素的质量浓度分别在16.8~67.2tLg/mL(r=0.9991)、5~60I~g/mL(r=0.9991)范围内与各自峰面积积分值呈良好的线性关系;平均回收率和RSD分别为100.58%、100.53%和1.62%、1.74%(n=9);贴敷24
3、、48、72h后的祖师麻膏药中祖师麻甲素和7一羟基香豆素的平均残留率分别为69.45%、53.12%、30.00%和93.23%、88.28%、86.74%。结论祖师麻膏药使用后祖师麻甲素和7一羟基香豆素的残留较多,后者更明显存在差异。关键词:祖师麻膏药;祖师麻甲素;7-羟基香豆素;残留量;高效液相色谱法中图分类号:R927.2文献标志码:A文章编号:1001—1528(2013)06—1209-04doi:10.3969/j.issn.1001-1528.2013.06.022Determinationofresidualam
