Comparative study on the extraction of eleutheroside B from Acanthopanacis senticosi Radix Et Rhizoma Seu Caulis by ultrasonic method and flash extraction method
To optimize the extraction process of eleutheroside B from Acanthopanacis senticosi Radix Et Rhizoma Seu Caulis by ultrasound and flash extraction based on orthogonal experiments,and the extraction effects of the two best processes were compared.The extraction rate of eleutheroside B was used as an evaluation indicator and the orthogonal test of ultrasonic method and flash extraction method using L9(34)was designed.The content of eleutheroside B was determined by high performance liquid chromatography method.The results showed that the extraction rate of ultrasound method was significantly higher than that of flash extraction method,the optimum extraction process was as follows:extraction solvent of 30%ethanol,extracting time of 0.75 h,ultrasonic power of 200 W,material-liquid ratio of 1∶5(g/mL).This study could provide references for the development and utilization of Acanthopanacis senticosi Radix Et Rhizoma Seu Caulis in the field of feed.
