目的 建立消肿散瘀软膏的质量控制标准。方法 采用系数倍率分光光度法。结果 能直接消除空白基质的背景干扰。平均回收率为 97.94 % ( RSD=1.0 3 % )。在 2 .4 6～ 2 4 .6μg/ m L浓度范围内线性良好 ( r=0 .9998)。结论 方法简便、经济、重复性好 ,可用于消肿散瘀软膏的质量控制。
Objective To establish the quality control standard of Xiaoying Sanyu ointment. Methods Factor magnification spectrophotometry was used. Results The background matrix interference can be eliminated directly. The average recovery rate was 97.94 % (RSD = 1.0 3 %). Linearity was good in the range of 2.46～24.6μg/m L (r=0.9998). Conclusions The method is simple, economical and reproducible. It can be used for the quality control of Xiaoxie Sanyu ointment.
