摘要
目的:探讨甲醇用量、浓度和提取次数对芦丁提取率的影响.方法:利用高效液相色谱法测定不同提取条件下黑苦荞中芦丁的产率.结果:固液比为1:15,甲醇浓度为80%,提取2次,黑苦荞中的芦丁提取率高.结论:提取液用量,料液比和提取液浓度对芦丁的提取率都有影响,其中影响最大的是甲醇浓度,其次为提取次数.
Objective: to explore the effects of the dosage,density and extraction times of methanol.Method: The yields of rutin from black buckwheat extracted under different conditions were determined by HPLC.Result: The optimum conditions for the extraction of rutin from black buckwheat were: material-solvent ratio was1:15,80% methanol in water as extraction solvent,and extracted for 2 times.Conclusion: All the investigated parameters had significant effects on the extraction efficiency of rutin from black buckwheat,while the concentration of methanol was the most important factor.
