简介：摘要目的探索清喉消炎颗粒的最佳提取条件,为清喉消炎颗粒的制备、质量控制和临床应用提供理论依据.方法以出膏率为指标,采用正交试验法对清喉消炎颗粒提取进行优选,实验选择浸泡时间、煎煮时间、含醇量三个因素,每因素三个水平,用L９(３３)正交表进行实验设计.结果清喉消炎颗粒的最佳提取工艺是加水煎煮两次,浸泡时间１??５h、煎煮时间１h和２/３h、含醇量５５％.结论在优选条件下,清喉消炎颗粒出膏率高,以此条件制备清喉消炎颗粒,并对处方中主药板蓝根和岗梅根进行定性鉴定,进一步证明此提取工艺的合理可行.关键词清喉消炎颗粒;正交试验法;定性鉴定TheOrthogonalTestofXiaoYanQingHouGranulesextractionWUYue－hong,HUANGLe－shan,HUANGHan－hui,WULi－min(Dept??ofPharmaＧcy,TheThirdaffiliatedHospitalofGuangzhouMedicaluniversity,Guangzhou５１０１５０,China;GuangzhouMedicalUniversity,Guangzhou５１０１８０,China)AbstractObjectiveThroughexploretheextractionprocessofXiaoYanQingHougranulestoprovideatheoreticalbasisfortheXiaoYanQingHougranulespreparation,thequalitycontrolandtheclinicalapplication??MethodsUsingtherateofextractionasindexandbasingontheorthogonaltestmethodtooptimizeXiaoYanQingHougranules’extractionprocess??TherewerethreemainfactorsintheExperimentsoakingtime,decoctingtime,alcoholcontent,andeachfacＧtorhadthreelevels??TheexperimentaldesignusedL９(３３)orthogonaltable??ResultsTheoptimizedextractiontechnologyfollowedasdecoctingtwotimes,soaＧkingtime１??５hourdecoctingtime１hourand２/３houralcoholcontent５５％??Conclusion,Undertheoptimizationconditions,XiaoYanQingHougranules’rateofextractionwashigh,toproduceXiaoYanQingHougranules,sowemakesomequalitativeidentificationofmaindrugsintheprescriptionofRadixIsatidisandGangKMeeyigweonrtdosprovethisprocessarerationalityandfeasibility??XiaoYanQingHougranules;Orthogonaltest;Qualitativeidentification中图分类号R２９１文献标识码A文章编号１００８－６３１５(２０１５)１２－０６１２－０２
