Abstract:The extraction and purification of red pigment from rose was studied. the optimal ethanol extraction conditions were as follows: extraction time was 3h; the extraction temperature was 70℃; and the ratio of rose to 70% ethanol was 1:10. The obtained original extracts were then purified with DA 101 Macroporous Resin. Results showed that the color value of purified extracts was 8 times higher than that of original extracts.
