RESUMEN
OBJECTIVE:To establish a method for content determination of astragaloside in Danggui buxue formula granule, and investigate the influence of different conditions of dissolution on the content. METHODS:HPLC was performed on the column of Aglient C18 with mobile phase of acetonitrile-water(28:72,V/V)at flow rate of 1.0 ml/min,column temperature was 25 ℃,and the injection volume was 10 μl. RESUITS:The linear range of astragaloside was 2.91-17.46 μg;RSDs of precision,stability were lower than 2%,and reproducibility tests was 3.63%,recovery was 95.76%-98.20%(RSD=1.03%,n=6). The optimized use method was mixing the two granules with 80 ℃ hot water and keeping heat preservation for 5 min successively before taken. CON-CLUSIONS:The method is simple and reproducible,and can be used for the content determination of astragaloside in Danggui bux-ue formula granule.
RESUMEN
AIM: To prepare traditional Chinese medicine formula Danggui Buxue Pellets by extrusion-spheronization and to study the optimal process and formulation. METHODS: Danggui Buxue Pellets were prepared by a new style extrusion-spheronization equipment;The optimal process and formulation were obtained on the studies of influenitial factors and L_9(3~4) orthogonal design,The micromeritic properties and reception percentage of pellets were determined. RESULTS: The prepared Danggui Buxue Pellets by extrusion-spheronization were all spheral with smooth surface;The percent of reception was not less than 85%. CONCLUSIONS: Extrusion-spheronization is suitable to produce herbal medicine pellets.The preparation process is simple and feasible;The quality of the prepared pellets is excellent and the percent of reception is high.
