1、專業(yè):藥物分析雷公藤藥材及制劑的HPLC指紋圖譜研究高旋*,莊瑩,宋敏,翟清波,杭太俊(中國(guó)藥科大學(xué)藥物分析教研室,南京210009)摘要目的:建立雷公藤藥材及制劑的HPLC指紋對(duì)照測(cè)定法,為雷公藤質(zhì)量控制提供參考。方法:采用C18色譜柱,甲醇-水為流動(dòng)相梯度洗脫,測(cè)定雷公藤藥材及制劑的HPLC指紋圖譜,統(tǒng)計(jì)分析確定共有模式;以最接近共有模式的雷公藤藥材和制劑為指紋對(duì)照,采用夾角余弦法和相對(duì)歐氏距離法,分別從化學(xué)成分定性和含量?jī)蓚€(gè)方面對(duì)不同產(chǎn)地雷公藤藥材和主要市售雷公藤片劑的HPLC指紋圖譜進(jìn)行定性與定量相似性評(píng)價(jià)。結(jié)果:建立的雷公藤藥材及制劑的HPLC指紋圖譜
2、測(cè)定條件分離良好、專屬性強(qiáng),可用于全面控制雷公藤的質(zhì)量。結(jié)論:以指紋對(duì)照品為參照進(jìn)行雷公藤藥材及制劑指紋圖譜相似性評(píng)價(jià),重復(fù)性和耐用性良好。測(cè)得雷公藤藥材及制劑的指紋特征差異顯著。關(guān)鍵詞:雷公藤藥材;雷公藤片劑;雷公藤內(nèi)酯醇;指紋圖譜;高效液相色譜法1StudyofTripterygiumwilfordiiHook.fandtripterygiumtabletsbyHPLCFingerprintChromatogram*GAOXuan,ZHUANGYing,SONGMin,ZHAIQing-bo,HANGTai-jun(ChinaPharmaceuticalUn
