篇名: | HPLC法测定当归补血配方颗粒中黄芪甲苷的含量 |
TITLE: | |
摘要: | 目的:建立测定当归补血配方颗粒中黄芪甲苷含量的方法,并考察不同冲化条件对其含量的影响。方法:采用高效液相 色谱法。色谱柱为Agilent C18,流动相为乙腈-水(28 ∶72,V/V),流速为1.0 ml/min,柱温为25 ℃,进样量为10 μl。结果:黄芪甲苷检 测进样量线性范围为2.91~17.46 μg;精密度、稳定性的RSD<2%、重复性试验的RSD=3.63%,加样回收率95.76%~98.20%, RSD为1.03%(n=6)。较佳冲服方法为将两种颗粒混合后用80 ℃水冲化,保温5 min后服用。结论:本方法操作简便、重复性好, 可用于当归补血配方颗粒中黄芪甲苷含量的测定。 |
ABSTRACT: | 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. CONCLUSIONS: The method is simple and reproducible,and can be used for the content determination of astragaloside in Danggui buxue formula granule. |
