ABSTRACT
OBJECTIVE:To optimize the extraction technology of berberine from Rhizoma Coptidis.METHODS:The or?thogonal-test method was adopted to research the effects of5factors,including the concentration and volume of alcohol,the concentration of H 2 SO 4 ,the duration and times of extraction on the yielding rate of berberine from Rhizoma Coptidis.RESUL TS:The optimum technology of extracting berberine from Rhizoma Coptidis was described as follows:The concentration of al?cohol containing0.25%H 2 SO 4 was80%,and volume of alcohol was6times raw herb.To extract the herb for3times was optimum and duration of extraction was1.5h for each time.CONCLUSION:The content of berberine in the product is over90%,so this technology is suitable for industrialized production.
