| Abstract: | Objective] Ultrasonic extraction processing of Houttuynia cordata Thunb. polysaccharides was studied. Method] The Houttuynia cordata Thunb. polysaccharides were extracted by ultrasonic extraction method. The best extraction processing was obtained by using single factor experiment and L_9(3~4)orthogonal methods. Method] It was concluded that the optimal conditions of extraction were as follow: material to lipuid ratio 1∶ 25,extraction temperature 80 ℃,extraction time 40 min. Under this conditions,the yield of polysaccharides was 5.82%. Conclusion] Ultrasonic extraction has the advantage of saving solvent,time,energy and high extraction ratio. |
