Bee products from urban apiaries are increasingly used. They are mainly used to promote local apiaries and cities in which they are located. The aim of the study was to compare the chemical composition and antioxidant activity of propolis from 6 Polish apiaries located in cities (Legionowo, Torun, Cracow, Warsaw, Katowice, Lodz). The chemical composition was analyzed using liquid chromatography (HPLC-DAD) and the analysis of antioxidant activity by scavenging free radicals (ABTS and DPPH) and FRAP. The obtained results showed the presence of 24 phenolic compounds in propolis extracts. The tested samples showed differentiation in terms of the content of individual chemical components, however, cinnamic acid and its derivatives were dominant. High antioxidant activity of the tested extracts was demonstrated (ABTS was in the range of 16.80-51.53 mg Te/mL, DPPH was in the range of 7.54-22.13 mg Te/mL, while FRAP reduction was in the range of 10.93-29.55 mg Te/mL). The obtained results compared with literature data on propolis from agricultural areas allow to conclude that propolis samples from both Poland types of areas are similar and can be classified as poplar propolis.
城市养蜂场的蜂产品越来越多地被使用。它们主要用于推广当地的养蜂场和所在城市。本研究的目的是比较 6 个位于波兰城市（Legionowo、Torun、Cracow、Warsaw、Katowice、Lodz）的养蜂场的蜂胶的化学成分和抗氧化活性。使用液相色谱（HPLC-DAD）分析化学成分，并通过清除自由基（ABTS 和 DPPH）和 FRAP 分析抗氧化活性。所得结果表明，蜂胶提取物中存在 24 种酚类化合物。测试样品在单个化学组分的含量方面表现出差异，但肉桂酸及其衍生物占主导地位。测试提取物表现出高抗氧化活性（ABTS 的范围为 16.80-51.53mgTe/mL，DPPH 的范围为 7.54-22.13mgTe/mL，而 FRAP 还原的范围为 10.93-29.55mgTe/mL）。与农业地区蜂胶的文献数据进行比较，可以得出结论，来自波兰这两种类型地区的蜂胶样品相似，可以归类为杨树蜂胶。
