邻苯三酚法测定超氧化物歧化酶缓释片中SOD的活性

Determination of superoxide dismutase activity in its sustained release tablets by Pyrograllol autoxidation

目的建立超氧化物歧化酶 (SOD)缓释片的活性测定方法。方法采用邻苯三酚自氧化法。结果在SOD浓度为 0 .0 6 0～0 . 0 0 6mg·ml-1时线性关系良好 (r=0 .9996 ) ;平均空白加样回收率为 10 1 .94 % (n=9)。结论所用方法简单、快速 ,结果准确。

OBJECTIVETo establish a method for determination of superoxide dismutase activity in its sustained release tablets. METHODSThe method of Pyrograllol autoxidation was used. RESULTSThe linearity was good within the range of 0.060-0.006 mg·ml -1(r=0.9996).The average recovery was 101.94%(n=9).CONCLUSIONThe proposed method appears to be simple, rapid, accurate and reliable.
