[Display omitted] • An efficient and accurate method for polyamine detection was established. • This method can be used to detect polyamines in poultry tissues. • Uncovering the distribution pattern of polyamines in poultry tissues. • To study the effect of exogenous spermine on polyamine deposition in geese. Polyamines are widely present in animal cells and perform important physiological and biochemical functions. Moderate intake of polyamines contributes to good health. Poultry is one of the common sources of polyamines in daily life. However, different tissues from poultry contain different amounts of polyamine. In this study, an efficient and accurate method for the determination of polyamines was developed by high-performance liquid chromatography (HPLC) with precolumn benzoyl chloride derivatization. The linearity of the polyamines was good between 10–400 nmol/mL, with the limit of detection (LOD, S/N = 3) and limits of quantification (LOQ, S/N = 10) were 0.37 and 1.23 nmol/mL. The recoveries of the method ranged from 94.73 % to 106.58 % with high accuracy (RSD < 7 %) and no significant matrix effects or interferences. The RSD of intra-day, inter-day and inter-batch repeatability in the range of 0.07–1.57 %, 0.08–1.03 % and 1.46–4.57 %. The method was successfully used to detect polyamines in poultry tissue, with putrescine, spermidine and spermine levels ranging from 3.24 to 29.85 mg/kg, 0.46 to 164.11 mg/kg and 63.39 to 489.57 mg/kg, respectively. Polyamine levels were higher in the spleen, thymus and bursa of fabricius and lower in the heart and muscle. Furthermore, the method was employed to study the effect of exogenous spermine on polyamine deposition in different tissues of geese. In summary, the method is suitable for the detection of polyamine in animal tissues. [ABSTRACT FROM AUTHOR]
