摘要: 建立了高效液相色谱法同时分析发酵辣椒中8种有机酸的方法。采用Hypersil-ODS2色谱柱(4.6mm×200mm,5μm),色谱条件为:2%甲醇-0.05mol/L KH2PO4(pH2.8)作为流动相,流速0.8ml/min,柱温17℃,进样量5μl,检测波长214nm。在此条件下,8种有机酸能够得到较好的分离,回收率92.87%~106.15%,RSD<3%。同时还比较了不同提取方法的提取效果,表明加热提取比超声波提取的效果更好。

Abstract: A method for simultaneous determination of 8 organic acids in fermented Capsicum by reverse phase high performance liquid chromatography was developed. Hypersil-ODS2 column(4.6 mm×200 mm, 5μm)was used at 17℃ and mobile phase was 2% CH3OH-0.05 mol/L KH2PO4(pH 2.8)with flow rate of 0.8 ml/min. Detection wavelength was 214 nm. The relative standard deviations were lower than 3%, and the recoveries were 92.87% to 106.15%. In this study, two methods (extracted with heating or ultrasonic) were used to extract organic acids, it is proved that extraction with heating is better than ultrasonic.
