【摘要】 采用超声波辅助浸提方法分别对栀子多糖和山楂黄酮进行浸提。通过单因素试验和正交试验,分别取得栀子多糖浸提最佳工艺条件:浸提温度50℃,浸提时间60 min,料水比1∶15;山楂黄酮浸提最佳工艺条件:乙醇溶液体积分数80%,浸提温度60℃,浸提时间45 min,料液比1∶25。所得山楂黄酮浸提液经40℃,0.1 MPa的减压蒸馏,除去乙醇。更多还原

【Abstract】 Gardenia polysaccharides and hawthorn flavonoids were respectively extracted by ultrasonic assisted extraction means. Optimum extracted conditions of gardenia polysaccharide which get through single factor experiments and orthogonal experiments were: extraction temperature of 50 ℃,extraction time of 60 min,and feed water ratio of 1∶ 15. The optimum extraction conditions of hawthorn flavonoids were: volume fraction of 80% ethanol solution,extraction temperature of 60℃,extraction time of 45 min,and solid-liquid ratio of 1:25. Ethanol in hawthorn flavonoids extract was removed through vacuum distillation of 40 ℃,0. 1 MPa condition.更多还原
