| Abstract: | Objective To improve the pretreatment methods and optimal conditions. Methods Sophora alopecuroides seeds powder were soaked for 3 hours with 10% NaOH solution.The extract was extracted with 1:8 of n-butyl alcohol and chloroform mixed solvent. Results The average recovery was 95.82%,and RSD was less than 4%. Conclusion The modified method can abate emulsification and improve extractive rate of total alkaloids in sophora alopecuroides. |
