摘要:

 以高效液相色谱法测定鸡排泄物中的二甲氧苄啶的浓度,研究鸡口服二甲氧苄啶在排泄物中的排泄规律。选用20只白羽肉鸡随机分为2组,分别按体重口服10、20 mg•kg-1的二甲氧苄啶,在给药后的2、4、8、16、24、32、48、72 h收集鸡的所有排泄物。采用HPLC法测定鸡排泄物中二甲氧苄啶的浓度。给药后原形药物很快随排泄物排出体外,10 mg•kg-1体重剂量组总排泄原形药物占给药剂量的21.63%,20 mg•kg-1体重剂量组总排泄原形药物占给药剂量的24.13%。由此可知,二甲氧苄啶在鸡体内原形药物在排泄物中排泄不完全,可能存在其他代谢物和原形药物的葡萄糖醛酸结合物。

Abstract:

 A high performance liquid chromatography (HPLC) method was developed for the determination of diaveridine in chicken excreta to explore excretion regularity of diaveridine in chicken excreta.Twenty healthy white feather broiler chickens were randomly divided into 2 groups of 10 chickens each,the 2 groups were orally administered at a dosage of 10,20 mg•kg-1 body weight of diaveridine,respectively.The all excreta of chicken were collected at 2,4,8,16,24,32,48,72 h,respectively.The concentration of diaveridine was analyzed by HPLC.Diaveridine was excreted quickly with excreta after oral administration.The total recovery of diaveridine was 21.63% at a dosage of 10 mg•kg-1 body weight and 24.13% at a dosage of 20 mg•kg-1 body weight,respectively.The results indicate that prototype drug of diaveridine in chicken is incompletely excreted,and there probably exist other metabolites and glucuronide conjugates of prototype drug in the excreta.

Key words: diaveridine, chickens, excreta, excretion
