摘　　要：采用紫外分光光度法建立了丹皮酚聚乳酸微球中药物含量的测定条件，测定微球中丹皮酚的含量。结果表明，丹皮酚的线性浓度范围为5．80～34．80ug/ml，回归方程为A=0．0664C＋0．0245，相关系数r=0．9974，平均回收率为99．37％（RSD=0．66％）。Using ultraviolet spectrophotomethy, the optimal conditions for the determination of paeonohm in polylactic acid microspheres were estabhshed, and the concentration of paeonolum was analyzed. The linear of calibration for paeonolum was 5.80 - 34.80 μg/ml, and the regression equation was A = 0.0664C ＋ 0.0245, with the correlation of 0.9974. The average recovery was 99.37 % （ RSD= 0. 66%）.
