摘　　要：建立了鸡骨草中常用农药残留的分析方法,并进行了残留量风险评估。采用QuEChERS法净化、UPLC-MS/MS法对50批鸡骨草中11种农药进行测定;点评估模式计算长期摄入风险,以ADI表示;危险指数法评估多农药残留的联合暴露风险,以HI表示;借鉴兽药残留风险排序矩阵计算农药残留风险得分。结果表明:11种农药组分线性相关系数均>0.990,回收率为79.1%~117.1%;共检出5种农药,其中吡唑醚菌酯检出率最高;ADI为0.002%~0.048%,HI为0.001。该分析方法操作简单快速、准确可靠,适用于鸡骨草中农药残留分析测试。An analytical method for commonly used pesticide residues in Abrus cantoniensis Hance was established,and residual risk assessment was carried out.QuEChERS method was used for purification,and 11 pesticides were determined in 50 batches of Abrus cantoniensis Hance by UPLC-MS/MS;the point assessment model was used to calculate the long-term intake risk(ADI);the joint exposure risk of multiple pesticide residues was evaluated using the hazard index method,expressed as HI;using the risk ranking matrix of veterinary drug residues for reference,the risk score of pesticide residues was calculated.The results showed that the linear correlation coefficients of the 11 pesticide components were all greater than 0.990,with recoveries ranging from 79.1%to 117.1%.A total of 5 pesticides were detected,with the highest detection rate of pyraclostrobin;the ADI ranged from 0.002%to 0.048%,and the HI was 0.001.The analysis method is simple,fast,accurate,and reliable,and is suitable for the analysis and testing of pesticide residues in Abrus cantoniensis Hance.
