Abstract: In this experiment column chromatography composed of the macroporous adsorption resin was used to purify the extract of flavonoids in Alpinia officinarum Hance. The content of flavonoids in the sample and the yield, as an evaluation of the result of purification, was determined in UV spectrophotometer. The optimum technological parameters of purification were obtained, which included all the factors of affecting purification of flavonoids. The results showed the content of flavonoids in the sample was up to 90.32%, and the yield was 49.91% by means of purifications via macroporous adsorptionresin from Alpinia officinarum Hance.

Key words: Alpinia officinarum Hance, flavonoid, macroporous, adsorption resin, purification
