摘要
研究了β-隐黄素提纯过程中的皂化和柱层析工艺条件,结果表明:最佳皂化工艺条件为皂化剂10mg/100mL KOH-乙醇溶液、温度20℃、皂化时间12h、皂化液体积40mL、搅拌速率400r/min;柱层析最佳工艺条件为上样量与硅胶比1:125(mL/g),洗脱剂为正己烷-丙酮-甲醇溶液(92.5:7:0.5,V/V)、洗脱液流速1.0mL/min,最终得到的β-隐黄素纯度高于90%。
In the present study, we investigated optimal conditions of saponification and column chromatography for β-cryptoxanthin purification from satsuma mandarin. The optimal saponification conditions were found to be saponification with 40 mL of KOH-ethanol (10 mg/100 mL) at 20 ℃ for 12 h with stirring at 400 r/min. The optimal column chromatography conditions were 1:25 (mL/g), n-hexane-acetone-methanol (92.5:5:0.5, V/V) and 1.0 mL/min for sample/silica gel ratio, eluant and flow rate, respectively. The purity of the fl-cryptoxanthin under the optimized conditions exceeded 90%.
