Abstract:  The aim of this paper was to research an optimumly separated and purified method of Sophora alopecuroides L. The results of experiment determined that the most effective separating and purifing method for each ingredient in Sophora alopecuroides L. was a combined one by using alumina column followed recrystallization. Besides, the matrine and oxymatrine crystals obtained respectively from this experiment were analysed for their purification by high performance liquid chromatog- raphy (HPLC). Finally, we found that the purities of the two pured alkaloids both exceed 98%.

Key words: Sophora alopecuroides L., oxymatrine, matrine, separation and purification
