对液相色谱法测定山楂片中苯甲酸、山梨酸、糖精钠进行了方法优化,对色谱条件进行了调整,采用ODS—Cl8型(150 mm×4.6 mm,5μm)色谱柱,流动相甲醇—0.02 mol/L乙酸铵(体积比5∶95),流速为1.0 mL/min,采用紫外检测器,检测波长为230 nm。方法测定结果的相对标准偏差小于2%(n=4),平均回收率大于90%,该法满足实验要求。
對液相色譜法測定山楂片中苯甲痠、山梨痠、糖精鈉進行瞭方法優化,對色譜條件進行瞭調整,採用ODS—Cl8型(150 mm×4.6 mm,5μm)色譜柱,流動相甲醇—0.02 mol/L乙痠銨(體積比5∶95),流速為1.0 mL/min,採用紫外檢測器,檢測波長為230 nm。方法測定結果的相對標準偏差小于2%(n=4),平均迴收率大于90%,該法滿足實驗要求。
대액상색보법측정산사편중분갑산、산리산、당정납진행료방법우화,대색보조건진행료조정,채용ODS—Cl8형(150 mm×4.6 mm,5μm)색보주,류동상갑순—0.02 mol/L을산안(체적비5∶95),류속위1.0 mL/min,채용자외검측기,검측파장위230 nm。방법측정결과적상대표준편차소우2%(n=4),평균회수솔대우90%,해법만족실험요구。
The determination of benzoic acid(sodium) ,sorbic acid( potassium), saccharin sodium in haw slices by high performance liquid chromatography was optimized. The conditiong of sample preparation was adjusted accordingly. ODS - C18 ( 150 mm x 4.6 mm) was used as column, with mobile phase 0.02 mol/L NH4Ac/methanol(95/5 ) and velocity of flow 1.0 mL/min. Wavelength was 230 nm determined by UV detector. The average recovery rate was above 90% , and the RSD was less than 2% ( n = 4), which is suitable for the need of experiment.
