摘要
为同时测定动物源性食品中肾上腺素、多巴胺的含量,建立HPLC-MS-MS检测方法。该两种物质的线性范围均为3～1500μg/kg。低、中、高三种浓度加标回收率均为90%～101%;检出限分别为肾上腺素1μg/kg、多巴胺3μg/kg。本方法快速简便,灵敏度高,选择性好,测定结果令人满意,可在各食品检测机构推广应用。
In order to determine adrenalin and dopamine in animal-derived foods, a sensitive and rapid HPLC-MS-MS method was established. The standard curve was linear within the concentration range of 3 - 1500 μg/kg. The spike recovery rates of adrenalin and dopamine at high, medium and low levels averaged 90%- 101%. Meanwhile, the limit of detection was 1μg/kg for adrenalin and 3 μ g/kg for dopamine, respectively. This method is simple, sensitive and highly selective so that it can be extensively applied in food quality control.
