摘　　要：文章采用乙醇水溶液浸提川红橘皮黄酮类物质,研究了乙醇水溶液浓度、浸提温度、液料比、浸提时间对川红橘皮黄酮得率的影响;同时,比较了新川红橘皮与三年陈川红橘皮黄酮得率。实验结果表明,浸提川红橘皮黄酮类化合物最佳工艺条件为乙醇水溶液浓度50%,浸提温度80℃,液料比40∶1 m L/g,浸提时间60 min,最佳工艺条件下新制川红橘陈皮黄酮得率为6.232 mg/g;三年制川红橘陈皮黄酮含量8.384 mg/g。In this paper,flavonoids from Sichuan red orange peel were extracted with ethanol aqueous solution.The effects of ethanol aqueous solution concentration,extraction temperature,liquid-solid ratio and extraction time on the yield of flavonoid from Sichuan red orange peel were studied;at the same time,the flavonoid yields of Sichuan red orange peel and three-year old Sichuan red orange peel were compared.The results showed that the optimum technological conditions for extracting flavonoid from Sichuan red orange peel were ethanol aqueous solution concentration of 50%,extraction temperature of 80℃,liquid material ratio of 40∶1 mL/g and extraction time of 60 min.Under the optimum technological conditions,the yield of flavonoid from Sichuan red orange peel was 6.232 mg/g;the flavone content of three-year old Sichuan red orange peel was 8.384 mg/g.
