Abstract:
Object To optimize the preparation procedure for WEI'AN GRANULES Methods The optimum conditions of WEI'AN GRANULES were selected with the active components: magnolol, polysacchride of Rhizoma Atractylodis Macrocephalae and berberine hydrochloride as mark by orthogonal test Results The optimum preparative procedure was as follow: Cortex Magnoliae officinalis and Fructus Aurantii Immaturus were extracted with water and precipitated with alcohol (adding 20 fold water as much as medicine, extracting three times, 0 5 h per time and precipitated with 95% alcohol to remove impurities); Rhizoma Coptidis was extracted with 95% alcohol by refluxing; Rhizoma Atracylodis Macrocephalae and other herbs were extracted with water (adding 24 fold water as much as medicine, extracting twice, 2 h per time, its granule size of Rhizorna Afracylodis Macrocephalae was 2 mm to 4 mm) Conclusion The optimum preparative procedure is reliable and the extracting ratio of active component is high
