Abstract: Gardenia yellow was extracted with ethanol and water. The ratio of raw material and solvent, concentration of ethanol, circumfluence temperature and times, impacting on extracting quotiety of gardenia yellow, were ascertained. In the same time, the adsorption characteristic of 13 kinds of resins including HPD100A and H103 for gardenia yellow and geniposide were investigated. Gardenia yellow was purified with HPD100A and H103 and the purified gardenia yellow could be obtained with the colority more than 368 and OD value ess than 0.24.

Key words: gardenia yellow, purification, macroporous adsorption resin
