1、中國(guó)民族民間醫(yī)藥藥物研究·18·ChinesejournalofethnomedicineandethnopharmacyThemedicinestudyHPLC—DAD法同時(shí)測(cè)定銀黃含片中黃芩苷和綠原酸的含量陳越蔡小玲胡頻何潔桂林醫(yī)學(xué)院附屬醫(yī)院藥學(xué)部,廣西桂林541001【摘要】目的:建立同時(shí)測(cè)定銀黃含片制劑中黃芩苷和綠原酸含量的方法,及測(cè)定不同廠家銀黃含片中黃芩苷和綠原酸的含量。方法:采用HPLC法,用DAD檢測(cè)器,島津VP—ODSC18(250mm×4.6mm,5(m)色譜柱,流動(dòng)相:乙腈一0.4%磷酸溶液,梯度洗脫,
2、流速1.0ml·min~,檢測(cè)波長(zhǎng)為綠原酸327nm、黃芩苷280nm。結(jié)果:綠原酸和黃芩苷分別在0.17~3.40g和0.33~6.60p,g范圍內(nèi)線性關(guān)系良好(r=0.9999),平均加樣回收率分別為100.59%(RSD=0.94%)和98.91%(RSD=1.14%)。結(jié)論:本文建立的方法可以同時(shí)準(zhǔn)確地測(cè)定銀黃含片中綠原酸和黃芩苷的含量,方法快速、準(zhǔn)確、重復(fù)性好,可用于銀黃含片的質(zhì)量控制。【關(guān)鍵詞】銀黃含片;綠原酸;黃芩苷;高效液相色譜【中圖分類號(hào)】1284.1【文獻(xiàn)標(biāo)志碼】A【文章編號(hào)】1007—8517(2014
