Abstract:

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 β-cryptoxanthin under the optimized conditions
exceeded 90%.
