Abstract: This paper studied the method for gingerol purification from ginger by macroporous resin absorption resin and its relevant influential factors for extraction. The optimum process conditions were gathered as following: AB-8 for the resin type, the resin quantity adopted at 40mg gingerol per dry resin, hexane to ethanol at 7:3 as the eluting solvent, elution rate at 0.4ml/min. The content of gingerol in the purified oil reached 48.3%.

Key words: gingerol, ginger, macroporous resin, purification
