摘　　要：金丝桃蒽酮素（ＨＹＰ）是有多个羟基的醌类衍生物．在极性溶剂乙腈中，电子给体Ｎ，Ｎ－二乙基苯胺和电子受体甲基紫精、蒽醌均能有效猝灭其荧光．说明它既具有酚羟基的给电子性能，又有醌类化合物的受电子性能．ＨＹＰ与平面构型的蒽醌可能形成基态复合物，以不同的方式与其发生光致相互作用．ypericin(HYP) is a derivative of polyhydroxy substituted perylenequinones. In acetonitrile, the fluorescence of HYP can be quenched by electron donor: N,Ndiethylaniline and acceptors: methyl viologen, anthraquinone, indicating that HYP can act either as a electron acceptor like quinones or as a electron donor like phenols. HYP maybe forms charge transfer complex in ground state with anthraquinone which has a plane configurition and interacts with it in the different way.
