Optimization of Extraction Process of Polysaccharides from Actinidia arguta(Sieb.Zucc.)Planch.ex Miq.

摘要

[Objectives]To optimize the extraction process of polysaccharides from Actinidia arguta(Sieb.&Zucc.)Planch.ex Miq.[Methods]On the basis of single-factor tests,an orthogonal test was conducted with solid/liquid ratio,ultrasonic temperature,ultrasonic time and ultrasonic power as influencing factors.[Results]The optimal extraction process was as follows:solid/liquid ratio 1∶15(g/mL),ultrasonic temperature 50°C,ultrasonic time 50 min and ultrasonic power 90 W.Under the optimal extraction conditions,the extraction rate of polysaccharides reached 2.05%.[Conclusions]The method is simple and feasible,and can be used to optimize the extraction process of polysaccharides in A.arguta,in order to provide a theoretical basis for the further development and utilization of related resources.
