| 摘 要： | 采用新近发展的蒸汽爆破技术对银杏叶进行预处理提取黄酮类物质,通过单因素实验,采用响应面法进行处理过程中的多因素组合的工艺优化,研究汽爆压力、汽爆时间、固液比对黄酮提取效率的影响,建立并分析了各因素与处理后黄酮提取率的数学模型。得到的优化条件为:汽爆压力0.38 MPa,汽爆时间235 s,固液比1∶15。与传统有机溶剂提取法相比,蒸汽爆破预处理使提取率提高了2.1倍。

| Abstract: | In this study,Ginkgo Biloba leaves was pretreated by using the newly steam explosion to improve the yield of extraction of flavonoids.Based on the single factor experiments,the effects of steam explosion pressure,temperature and solid-liquid ratio on Ginkgo Biloba leaves were investigated by response surface methodology.A mathematical model was established and analyzed to describe the relationships between the studied factors and the response of the yield of flavonoids.The optimum pretreatment parameters were as follows: Steam explosion pressure of 0.38 MPa,steam explosion time of 235 s,solid-liquid ratio for 1∶15.Under the optimum conditions,the yield of flavonoids was higher about 2.1 fold than that tradition extraction method. |
