利用紫外线辐照过氧化氢水溶液方法产生羟基自由基，并通过电子自旋共振及自旋捕捉方法，对自旋加合物谱线的相对高度进行比较，得到地奥心血康浓度０．７１％，１．４３％和２．１４％时，分别清除掉羟基自由基６６％。８０％和１００％。并与甲酸钠进行比较，得到该药物的作用机制与药效信息。
Hydroxyl radical was generated by UV irradiation of aqueous solution of hydrogen peroxide, and the relative height of the spin adduct spectra was compared by electron spin resonance and spin-trap method to get 0.71% Diosgenin concentration. 43% and 2.14%, respectively, remove the hydroxyl radical 66%. 80% and 100%. And compared with sodium formate to get the drug’s mechanism of action and efficacy information.
