[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 L9(34)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.
