| 摘 要： | 以桂花为原料，进行色素提取工艺的优化研究。对浸提剂、乙醇浓度、料液比、萃取时间及萃取温度这5个因素进行单因素和正交试验。结果表明，乙醇为最佳浸提剂，最大吸收波峰为330nm。桂花色素的最佳提取工艺条件为：85％的乙醇、料液比1：15、萃取时间80min、萃取温度80℃；在此工艺条件下，测得桂花色素的吸光度值为1．424。

| Abstract: | Osmanthus flagrance is used as research material. The solvents,concentration of alcohol,ratio of material to liquid, extraction time and temperature are tested by the single-factor and orthogonal experiments. The results show that ethanol is the best solvent, and that the maximum absorption peak is 330 nm. The optimal ex- traction technology is that ratio of material to liquid is 1：15 with 85% ethanol under 80 ℃ for 80 minutes. After twice extractions, the absorbency is up to 1.424. |
