摘要
以油菜花粉为原料,采用亚临界水提取黄酮类化合物。通过单因素和正交实验确定最佳工艺条件。研究表明,最佳工艺条件为:料液比1∶25 g/m L、提取时间20 min、提取温度120℃、压力1.2 MPa,按最佳工艺条件提取黄酮类化合物,得率高达4.12%±0.05%。
Subcritical water treatment was used to extract flavonoids from cole pollen. The optimal conditions were ascertained by single factor test and orthogonal test. The results showed that the optimal conditions of subcritical water extraction were as following: the ratio of material to water 1∶ 25 g / m L,the time20 min,the temperature 120 ℃ and the pressure 1. 2 MPa. Under the conditions,the yield of flavonoids could reach up to 4. 12% ± 0. 05%
