| 摘 要： | 为确定桂花子中黄酮类物质的提取工艺，以黄酮得率为考察指标，比较不同溶剂对桂花子黄酮类物质的提取效果，并采用正交试验，研究提取溶剂浓度、提取温度、提取时间和料液比对桂花子黄酮类化合物提取的影响。确定最佳提取工艺条件为最佳提取溶剂为乙醇、乙醇体积分数60%、提取温度90℃、料液比1:50(m/V)、提取时间5h。在此条件下进行提取，黄酮的得率为3.96%。

| Abstract: | Six solvents were separately used to extract total flavonoids from seeds of Osmanthus fragrans Lour. Among of them, absolute ethanol exhibited the high extraction efficiency. The ethanol extraction procedure of total flavonoids was optimized by single-factor and L9(34) orthogonal array methods. The optimum extraction conditions were determined as follows: ethanol concentration 60%, solid/liquid ratio 1:50, and temperature 90 ℃ for an extraction duration of 5 h. Under these conditions, a maximum yield of total flavonoids of 3.96% was obtained. |
