Gingerols in ginger oleoresin were separated by AB8 macroporous adsorption resin and silica gel column chromatography. The samples were characterized by the gas chromatography-mass spectrometry method.The peak area normalization method was used to determine the relative percentage of the components and the rate of accumulation of gingerol was determined by contrasting with gingerol standard samples. The results showed that gingerols was concentrated on the 3rd and the 4th parts.
