In this paper, an attempt was made to produce flavonoids by means of tissue culture using the callus induced from apical cell of the safflower seedrings. The callus induced in dark didn't yield flavonoids, while five of flavonoids were induced under the light. One of them isolated from the callus under the light was assumed as quercetin by UV spectrum.
