Honey is a natural product with beneficial properties to health and has different characteristics depending on the region of production and collection, flowering, and climate. The presence of precursor amino acids of- and biogenic amines can be important in metabolomic studies of differentiation and quality of honey. We analyzed 65 honeys from 11 distinct regions of the State of Santa Catarina (Brazil) as to the profile of amino acids and biogenic amines by HPLC. The highest L-tryptophan (Trp), 5-hydroxytryptophan (5-OH-Trp), and tryptamine (Tryp) levels were detected in Cfb climate and harvested in 2019. Although we have found high content of serotonin, dopamine, and L-dopa in Cfb climate, the highest values occurred in honey produced during the summer 2018 and at altitudes above 900 m. Results indicate that the amino acids and biogenic amine levels in honeys are good indicators of origin. These data warrant further investigation on the honey as source of amino acids precursor of serotonin, melatonin, and dopamine, what can guide the choice of food as source of neurotransmitters.
蜂蜜是一种对健康有益的天然产品，其特性因生产和采集地区、花期及气候而异。氨基酸前体和生物胺的存在在蜂蜜分化和质量的代谢组学研究中可能具有重要意义。我们通过高效液相色谱法（HPLC）分析了来自巴西圣卡塔琳娜州11个不同地区的65种蜂蜜的氨基酸和生物胺谱。在Cfb气候条件下于2019年收获的蜂蜜中检测到最高水平的L-色氨酸（Trp）、5-羟色氨酸（5-OH-Trp）和色胺（Tryp）。尽管我们在Cfb气候条件下发现了较高含量的血清素、多巴胺和L-多巴，但最高值出现在2018年夏季生产且海拔高于900米的蜂蜜中。结果表明，蜂蜜中的氨基酸和生物胺水平是产地的良好指标。这些数据值得进一步研究蜂蜜作为血清素、褪黑素和多巴胺氨基酸前体来源的情况，这可以指导作为神经递质来源的食物选择。
