金丝桃素的形式电位测定在二甲亚砜中使用循环伏安法。观察到两个可逆的单电子还原和一个更不明确的多电子氧化。这些过程的形式电位与金丝桃素的可见光谱一致，表明金丝桃素在激发态下既是一种良好的氧化剂，又是一种良好的还原剂。
The formal potentials for hypericin are measured in dimethylsulfoxide using cyclic voltammetry. Two reversible one-electron reductions and a more poorly defined multielectron oxidation are observed. The formal potentials for these processes are consistent with the visible spectrum of hypericin and they indicated that hypericin is both a good oxidizing agent and a good reducing agent in the excited state.
