| Abstract: | Objective To establish a method for the determination of adriamycin content adriamycin poly lactic acid microspheres. Methods The ultraviolet spectrophotomethy （UV）method was used to analyze the content of adriamycin. Results The linearity of adriamycin was better in the rang of 7.5 to 15.0μg·ml^-1 ,C = 0.04007A ＋0.00867, r =0.9997 （ n = 6）. The loading amount was 5.93% and entrapment rate was 38. 3%. Conclusion This methed is simple, sensitive, accurate and repeatable, it can be used for the determination of adriamycin poly lactic acid microspheres. |
