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 L_9(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.
