Protein and phenolic compound content and antioxidant capacity were determined from honey bee collected unifloral pollen pellets from Ranunculus, Brassica, Filipendula, Rubus, Vicia, Trifolium, Epilobium, and Taraxacum species of boreal coniferous zone in Finland. The aim of the study was to investigate the relation between the chemical composition and the botanical origin of the pollen pellets. The protein content of pollen pellets ranged between 18.2 and 29.3%. One hundred and twenty phenolic components were detected from the samples and their total amount was highest in Brassica and the lowest in Taraxacum pollen pellets. Cinnamic acid content was high in Brassica and T. repens compared to other species. Most of the flavonoids in pollen pellets were flavonols, which were highest in Ranunculus, Filipendula and Epilobium originated pollen pellets. The pollen pellets of Ranunculus, Brassica, Filipendula, and T. repens had an antioxidant activity of over 80%. The lowest activities, about 40%, were measured in Taraxacum and Epilobium samples.

蛋白质和酚类化合物含量和抗氧化能力是从蜜蜂收集的单花花粉颗粒中确定的，这些花粉颗粒来自芬兰北方针叶区的毛茛属、芸苔属、Filipendula、悬钩子属、豌豆属、三叶属、外叶属和蒲公英属物种。该研究的目的是研究花粉颗粒的化学成分与植物来源之间的关系。花粉颗粒的蛋白质含量介于 18.2% 和 29.3% 之间。样品中检出120种酚类成分，总含量以芸苔属最高，蒲公英花粉粒最低。肉桂酸含量较高的芸苔属和白三叶与其他物种相比。大多数花粉颗粒中的类黄酮是黄酮醇，这是最高的毛茛，蚊子和柳叶菜起源花粉颗粒。的花粉粒料毛茛，芸苔，蚊子，和白三叶具有超过80％的抗氧化活性。在蒲公英和Epilobium样品中测得的活性最低，约为 40% 。
