摘　　要：为了优化栀子中藏红花素的提取工艺,以藏红花素的提取率为指标,采用单因素试验考查乙醇体积分数、料液比、超声时间和超声温度对栀子中藏红花素提取率的影响,正交试验优化藏红花素提取工艺。结果表明,正交试验优化的提取工艺为乙醇体积分数60%,料液比1∶50,超声时间40 min,超声温度60℃,栀子中藏红花素的提取率为64.25%。In order to optimize the extraction process of crocin from Gardenia jasminoides Ellis,taking the extraction rate of crocin as the index,the effects of ethanol concentration,solid-liquid ratio,ultrasonic time and ultrasonic temperature on the extraction rate of crocin from Gardenia jasminoides Ellis were investigated by single factor experiment,and the extraction process of crocin was optimized by orthogonal experiment.The results showed that the optimum extraction conditions were as follows:ethanol concentration 60%,solid-liquid ratio 1∶50,ultrasonic time 40 min,ultrasonic temperature 60℃,the extraction rate of crocin from Gardenia jasminoides Ellis was 64.25%.
