中药枳实提取工艺研究

目的:探讨枳实中主要有效成分提取的最佳工艺条件。方法:以橙皮苷、柚皮苷和辛弗林的含量为指标,研究枳实提取挥发油后其它有效成分的提取溶剂。在此基础上,采用正交设计L9(3)4表,确定最佳提取工艺。结果:采用乙醇提取橙皮苷含量明显高于水提取,柚皮苷和辛弗林含量无明显差异。结论:乙醇提取的最佳工艺条件为10倍量60%乙醇提取2次,每次1.0 h。

Study on the Extracting Technology of Fructus Aurantii Immaturus

Objective:To investigate the optimum conditions for extracting the major active components in Fructus Aurantii Immaturus.Method: According to the contents of Hesperidin,Naringin and Synephrine,the use of extraction solvent of the other active components of Fructus Aurantii Immaturus in which the volatile oil were distilled was studied.And L₉(3)⁴ orthogonal design was used to determine the optimum extraction conditions.Result: The content of hesperidin in the EtOH extraction was obviously higher than that in the water extraction,and the contents of naringin and synephrine had no significant difference.Conclusions:The optimum ethanol extraction conditions was 10 times amount of 60% alcohol,refluxed two times,1.0 hour each time.
