摘  要:
[目的]采用固相萃取-高效液相色谱法同时测定大豆发酵制品中的异黄酮含量。[方法]以乳酸、霉菌发酵大豆样品为试材,将发酵豆制品以60%的乙醇溶液超声波提取1 h,稀释后用SPE小柱做净化处理,以C18反相色谱柱(4.6 mm×250.0 mm,5.0μm),0.2%甲酸和乙腈进行梯度洗脱、流速为1.2 ml/min、紫外检测波长260 nm,同时测定4种大豆异黄酮含量。[结果]试验得出,发酵豆制品中4种大豆异黄酮的平均回收率分别为大豆甙96.7%、染料木甙97.9%、大豆甙元102.2%、染料木素103.1%。[结论]该方法可同时测定发酵豆制品中4种大豆异黄酮成分,数据准确,重现性好。

摘  要:
[Objective] To simultaneously determine isoflavones content of fermented soybean products by SPE and HPLC.[Method]The fermented soybean products are extracted for 1 hour by 60% ethanol solution,after diluted,carry out cleaning treatment by SPE column and carry out gradient elution by C18reversed-phase chromatographic column(4.6 mm × 250.0 mm,5.0 μm),0.2% formic acid and acetonitrile,with flow velocity of 1.2 ml / min and UV detection wavelength of 260 nm,the average recovery rate of four components is daidzin 96.7%,genistoside 97.9%,daidzein 102.2% and genistein 103.1%.[Conclusion]The method can simultaneously determine four kinds of soybean isoflavones content,the data is accurate and reproducibility is good.
