【摘要】 本文研究了在0.005mol/L NaH₂PO₄缓冲体系中,DL-苄丝肼在玻碳电极上的2.5次微分阳极溶出伏安法特性。DL-苄丝胼在+0.23V处（vs.SCE）有清晰氧化峰,在4.7×10^-8～6.2×10^-7mol/L其浓度与峰高呈定量关系。并建立了同时测定多巴丝肼胶囊中DL-苄丝肼和L-多巴含量的方法。试样测试结果令人满意。更多还原

【Abstract】 The 2.5th order differential anodic stripping voltammetric behaviour of DL-ben-serazide on the glass carbon electrode has been investigated in a buffer solution of 0.005 mol/L NaH₂PO₄ （pH 6.0）. A sensitive oxidation peak of DL-benserazide was measured at +0.23V （vs. SCE）. Its linear range was 4.7×10⁽-8～6.2×10^-7mol/L. The method has been applied to the determination of the amounts of DL-benserazide and L-3, 4-dihydroxyphenyl- alanine in capsulae levodope et benserazide hydrochloride with reliable results.更多还原
