The electrochemical behavior of chrysin in pH 2.0‐9.0 Britton‐Robinson (B‐R) buffer solutions was studied by the means of linear sweep voltammetry and cyclic voltammetry at a static mercury drop electrode. In different pH range of B‐R buffer solutions, chrysin could cause four reduction waves. In pH 2.0‐5.8 B‐R buffer solutions, wave P 1 yielded by chrysin is a one‐electron reduction wave, and wave P 1 ′ caused by further reduction of the products of wave P 1 in pH<3.0 B‐R buffer solution is also a one‐electron reduction wave. But in 3.0
