摘　　要：以4个胭脂萝卜品种为材料,比较了不同浸提剂对红色素的提取效果,研究了胭脂萝卜生长过程中红色素含量的动态分析.结果表明,胭脂萝卜红色素用50%的乙醇浸提效果最好,在胭脂萝卜生长过程中,从幼苗期到开花期,红色素含量不断增加,红色素含量达到最大为3%,从开花期到结果期,红色素含量逐渐下降.In this study, different extraction agents were： used to extract the red pigment from four carmine radish cultivars and the effects were compared, and a dynamic analysis was made of the red pigment content in different growth periods of the plant. The extraction agent 50 % ethanol gave the best result of carmine radish pigment extraction. During the growth periods of carmine radish, the content of red pigment increased steadily from the seedling stage to the flowering stage with a maximum content of 3% and decreased gradually from the flowering stage to the silique setting stage of the plant.
