蜂胶是一种由蜜蜂从各种植物来源收集的树脂状蜂箱产品，其成分和生物活性取决于季节和该地区的植被等多种因素。本研究的目的是评价季节效应对6个月采集的巴西蜂胶（EEP） 6型和12型乙醇提取物的抗菌活性和酚类成分的影响。采用MIC和MBC对变形链球菌Ingbritt 1600进行抑菌性能评价，采用紫外可见分光光度法、HPLC-RF法和GC-MS法对其化学成分进行分析。结果表明，蜂胶采集的季节影响其化学成分，导致其抗菌活性的变化。
The composition and biological activities of propolis, a resinous hive product collected by honeybees from various plant sources, depends on various factors such as season and vegetation of the area. The aim of this study was to evaluate the influence of the seasonal effect on the ethanolic extracts of Brazilian propolis (EEP) type 6 and type 12, collected during 6 months in terms of antibacterial activity and phenolic composition. The antimicrobial properties were evaluated by MIC and MBC on S. mutans Ingbritt 1600 and the profile of chemical composition by UV-visible spectrophotometry, HPLC-RF and GC-MS. The results demonstrated that the season in which propolis is collected influences its chemical composition, resulting in modifications in its antibacterial activity.
