Abstract: The purification technology of flavonoids from sesame leaves by means of absorbent resin chromatography was studied in this paper. The optimum conditions of purification are as follow: The crude flavonoids extracts are washed with water at pH8.0, and eluted with alcohol at concentration 70% (V/V). The purity of flavonoids is 31.6% in the extracts after purification.

Key words: sesame leaves, flavonoids, purification technology
