建立了截短侧耳素含量的 HPLC检测方法。采用 Agilent Zorbax C18色谱柱(250 mm×4.6 mm,5μm),流动相为CH3 CN-0.02 mol·L-1 KH2 PO4缓冲溶液(50∶50,体积比),流速1.0 mL·min-1,检测波长205 nm,进样量20μL,柱温25℃。结果表明,截短侧耳素浓度在0.12~2400μg·mL-1范围内与峰面积线性关系良好(R=0.9998),平均回收率为98.7%,检出限为2.24 ng,定量限为6.84 ng。该法简便、准确、专属性好。
建立瞭截短側耳素含量的 HPLC檢測方法。採用 Agilent Zorbax C18色譜柱(250 mm×4.6 mm,5μm),流動相為CH3 CN-0.02 mol·L-1 KH2 PO4緩遲溶液(50∶50,體積比),流速1.0 mL·min-1,檢測波長205 nm,進樣量20μL,柱溫25℃。結果錶明,截短側耳素濃度在0.12~2400μg·mL-1範圍內與峰麵積線性關繫良好(R=0.9998),平均迴收率為98.7%,檢齣限為2.24 ng,定量限為6.84 ng。該法簡便、準確、專屬性好。
건립료절단측이소함량적 HPLC검측방법。채용 Agilent Zorbax C18색보주(250 mm×4.6 mm,5μm),류동상위CH3 CN-0.02 mol·L-1 KH2 PO4완충용액(50∶50,체적비),류속1.0 mL·min-1,검측파장205 nm,진양량20μL,주온25℃。결과표명,절단측이소농도재0.12~2400μg·mL-1범위내여봉면적선성관계량호(R=0.9998),평균회수솔위98.7%,검출한위2.24 ng,정량한위6.84 ng。해법간편、준학、전속성호。
A method for determination of pleuromutilin content by HPLC was established.The HPLC condi-tions were as follows:Agilent Zorbax C18 column(250 mm×4.6 mm,5μm),mobile phase was acetonitrile-0.02 mol·L-1 potassium dihydrogen phosphate(50∶50,volume ratio),flow rate was 1.0 mL·min-1,detection wavelength was 205 nm,injection volume was 20μL,column temperature was 25 ℃.Results showed that the standard curve was linear with peak area in the pleuromutilin concentration range of 0.12~2 400μg·mL-1 with correlation coefficient of 0.9998,the average recovery rate was 98.7%,the detection limit was 2.24 ng,the quantitative limit was 6.84 ng.This method is simple,accurate and has good specificity.
