Study on the Extraction Process of Polysaccharides from FRUCTUS CHAENOMELIS by Ultrasonic Technology

摘要(Abstract):

[Objective] To optimize the extraction process of polysaccharides from FRUCTUS CHAENOELIS.[Method] The effects of solid-liquid ratio,ultrasonic temperature,ultrasonic power and ultrasonic action time on the extraction of polysaccharides from FRUCTUS CHAENOMELIS were studied through single-factor test and orthogonal test.[Result] The optimum ultrasonic conditions for extracting polysaccharides from FRUCTUS CHAENOMELIS were solid-liquid ratio 1:70 (g/ml),ultrasonic temperature 80 ℃,ultrasonic power 140 W and ultrasonic action time 50 min.Under these conditions,the yield of polysaccharides was 12.81%.[Conclusion] The ultrasonic technology is a simple,time-saving and high efficient method to extract polysaccharides from FRUCTUS CHAENOMELIS.
