摘要
采用乙腈提取、硅胶柱净化、HPLC的检测方法，研究了噁唑菌酮在柑橘中的残留动态。结果表明，方法的回收率为79．28％～101．47％，变异系数为3．27％～6．69％。噁唑菌酮在橘皮中的降解回归方程为Ct=0．5401e^-0.0751t，r=-0．9672。嗯唑菌酮在橘皮中半衰期为9．2d。初步提出了该药在柑橘上的安全使用标准。
The residue of famoxadone in citrus was studied by acetonitrile extraction, gel column purification, and HPLC-UV detection. The results showed that recovery rates of this method ranged from 79.28% to 101.47% with the variation coefficient of 3.27% -6.69% .The regressive equation for dissipation of famoxadone in citrus peel was Ct=0.5401e^-0.0751t and the correlation coetfficient （r） was 0. 9672. The half-lives of famoxadone in citrus peel were 9.2 d. The criteria of savety-application of famoxadone in citrus was preliminarily proposed.
