Abstract: The extraction conditions of natural pigment from Impatiens balsamina L. were investigated by single factor experiment. The results were: ethanol(pH 1)of extraction solvent, 1.5 h of extraction time, 50 ℃ of extraction temperature, and 1︰70 of solid-liquid ratio by extracting for one time, respectively. Furthermore,the extraction conditions were optimized by orthogonal experiment, and the results were demonstrated as: ethanol(pH1)of extraction solvent, 60 ℃ of extraction temperature, 1.5 h of extraction time, respectively. And the extraction rate of pigment was reached to 2.84.

Key words: Impatiens balsamina L., natural pigment, extract method, optimization
