摘要
以总黄酮提取率为考察指标,研究了红枣皮渣中总黄酮的最佳提取工艺条件。通过单因素和正交试验,确定了红枣皮渣中黄酮的最佳提取条件:乙醇浓度为70%,料液比为1∶25,提取温度为80℃,提取时间为2.5h。该条件下黄酮的最佳提取率为1.72%。
The extraction of total flavonoids from Jujube Pomace was studied. The single - factor experiments and orthogonal experiment showed that the optimum conditions of the extraction were ： ethanol density 70%, material/liquid 1 ： 25, temperature 80 ℃, extracting time 2. 5 hours. Under these conditions, a maximum yield of total flavonoids was 1.72%.
