以色素提取率为指标,通过不同温度、时间、料液比等条件对超临界CO2提取五味子木脂素后的萃余物进行红色素提取技术研究,优化了其色素提取工艺,得出最优提取条件为浓度70%乙醇,料液比1∶20,提取温度50℃,提取时间25min。此条件下北五味子色素含提取率为1.832%。 Taking the extraction rate of pigment as index, the extraction technology of red pigment extracted by the extraction of Schisandra lignans by supercritical CO2 was studied by the conditions of different temperature, time, liquid-liquid ratio and so on, and the pigment extraction process was optimized to obtain the optimal The extraction conditions were 70% ethanol, solid-liquid ratio 1:20, extraction temperature 50 ℃, extraction time 25min. Under this condition, the extraction rate of Schisandra chinensis pigment was 1.832%.
