Pomegranate flower's red pigment is a natural red pigment with high quality. It has widely application value in medicine, food and light industries. In this paper pomegranate flowers were chosen as raw materials for extract pomegranate red pigment, the extraction conditions is studied systematically, the effects of extracting solvent concentration, temperature, material liquid ratio, extraction time and extrac- tion times on the extraction of pomegranate flower's red pigment were determined by using a single factor and orthogonal test. The results show that the maximum absorption wavelength of pomegranate flowers red pigment is 500nm, the optimum technological condition of extracted red pigment from pomegranate flowers were: 50% ethanol with pH (2 - 3) could be used as extracting solvent, the temperature of ex- traction was 40 ℃, extraction time was 3h, material liquid ratio was 1:10, extraction times were 4 times.
