Abstract:

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(GC-MS) 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. It identified 19 ingredients in the 4th part, which has the highest concentration of gingerols. The peak area percentage of gingerols was 14.34％ and the absolute rate of enrichment was 59.01％ with the former method, and the gingerols mostly focused on the former 5 eluate, of which only 11 elements was identified with high content in sample 2. The peak area percentage of gingerols was as high as  55.68% with the absolute rate of enrichment 70.88％ by the latter method.
 

Key words: gas chromatography-mass spectrometry method, gingerols, macroporous adsorption resin;silica gel adsorption chromatography
