發(fā)布時(shí)間:2018-11-04 20:09
【摘要】:目的:建立黨參、蜜炙黨參及米炒黨參指紋圖譜,為黨參不同炮制品質(zhì)量控制及炮制原理研究提供依據(jù)。方法:采用HPLC色譜法,Inertsil ODS C_(18)柱(250 mm×4.6 mm,5μm),流動(dòng)相為乙腈-水,梯度洗脫,柱溫30℃,檢測波長268 nm,對黨參及其2種炮制品進(jìn)行指紋圖譜研究,采用指紋圖譜相似度軟件進(jìn)行分析。結(jié)果:建立了黨參及其2種炮制品指紋圖譜,分別指認(rèn)了黨參炔苷和5-羥甲基糠醛2個(gè)色譜峰。蜜炙黨參和米炒黨參均增加了一個(gè)新成分5-羥甲基糠醛,黨參經(jīng)炮制后所含成分的量亦有不同程度的變化。結(jié)論:該法精密度、重復(fù)性、穩(wěn)定性良好,符合指紋圖譜技術(shù)要求,可作為黨參炮制品的質(zhì)量控制方法。
