1、云南中醫(yī)中藥雜志2014年第35卷第8期HPLC—DAD法同時測定清肺抑火片中4個成分的含量康紹建,何雨芹,張雯潔(云南省食品藥品檢驗(yàn)所,云南昆明65001l;2.云南農(nóng)業(yè)大學(xué),云南昆明650201)摘要:目的建立HPLC法同時測定清肺抑火片中梔子苷、黃芩苷、大黃素和大黃酚的含量。方法采用WatersC。8色譜柱(4.6mm×250mm,5Ixm),以乙睛(A)一0.2%磷酸(B)為流動相梯度洗脫,流速1.0mL·min~,采用DAD檢測器在200—4OOnm波長處進(jìn)行檢測。柱溫30℃。結(jié)果調(diào)取不同
2、波長的色譜圖分別計(jì)算各成分的含量,梔子苷(237nm)、黃芩苷(277am)、大黃素(254nm)和大黃酚(254nm)進(jìn)樣量分別在0.2825~5.650Ixg(r2=1);0.719~14.383Ixg(r2=0.9999);0.0415—0.83Ixg(r2=0.9998);O.0440~0.8795Ixg(r2:0.9999)范圍內(nèi)呈現(xiàn)良好的線性關(guān)系。平均回收率(rt=6)分別為97.93%,97.89%,97.91%,98.04%;RSD分別為0.14%,0.47%,0.45%,0.21%
