| Abstract: | OBJECTIVE To confirm the best procedure for Rhizoma Ploygoni cuspidati ethanol extraction. METHOD The procedure was optimized by orthoral test.RESULTS The best condition for procedure was to apply 70% ethanol, thirty times of the weight of original material, extraction two time and each extraction times was 2h.CONCLUSION The result is credible,the method is simple . It can be used for batch production. |
