【摘要】 目的:对从竹叶中提取竹叶总黄酮的工艺进行优化。方法:利用单因素试验确定浸提溶剂和浸提次数,利用正交试 验法进行工艺优化。结果:利用φ=60％乙醇,控制固液比为1:10,80℃浸提两次,每次1 h,提取效果最好。结论:该结果对 进一步的工艺开发有较好的参考价值。更多还原

【Abstract】 Objective: To optimize the extracting process for total flavonoids from bamboo leaves. Methods: selecting the solvent and extracting times based on single factor experiments and optimizing the extracting process by orthogonal test. Results: the best results can be achieved at the following conditions:ψ =60% ethanol as solvent, regulating the solid to liquid ration to 1 : 10, 80℃ , extracting two times, and last for about 1 h each time. Conclusions: it is very useful for further developement of inductrial process.更多还原
