摘要
目的 :研究化橘红中黄酮成分的提取工艺。方法 :以化橘红中柚皮苷含量为指标 ,采用正交试验法进行优选 ,并用HPL C测定柚皮苷含量。结果 :乙醇浓度和提取次数是化橘红中黄酮成分有效成分提取的关键因素 ,其次是提取时间 ,溶媒用量为最次要因素。结论 :最佳提取工艺为化橘红用 8倍量 80 %乙醇回流提取 3次 ,1.5 h/次。
Objective: To study the optimum extraction of Citrus grandis ‘Tomentosa'. Methods: Referring to the content of naringin, we study the optimum extraction by orthogonal design and the content of naringin by HPLC. Results: The content of ethanol and the extraction times are the first key factors, the time of extracting is the second, and the amount of solvent is the last. Conclusion: The optimum extraction is as follows: adding 8 times of 80% ethanol into Citrus grandis ‘tomentosa', and boiling for 1.5 hours each time, extracting three times in all.
