【摘要】 以橘皮为原料,探讨橘皮黄酮提取的最佳工艺条件。考察乙醇浓度、料液比、提取时间和提取温度等因素对橘皮黄酮得率的影响,在单因素试验的基础上,进行L9(34)正交试验。结果表明,最佳提取工艺条件为:乙醇浓度为65%,料液比为1:15,提取时间为40 min,提取温度为65℃,在此条件下,橘皮黄酮得率为8.94%。更多还原

【Abstract】 We explore the optimum extraction conditions of flavonoid from orange peel.Considering the factors such as the ethanol concentration,the solvent-material ratio,the extraction time and the temperature to impact on the yields of flavonoid from orange peel,by a single factor experiment,we test it orthogonal by L9(34).The results show that theoptimum extraction conditions are as follows: ethanol concentration 65%,solvent-material ratio 1∶15,extraction time 40min and extraction temperature 65℃.Under these conditions,the maximum extraction efficiency of flavonoid could reach up to 8.94%.更多还原
