Investigation of Flavonoid Aglycones in Propolis Collected by Two Different Varieties of Bees in the Same Region

Abstract

The quality and quantity of flavonoids from two types of propolis collected by two different varieties of Apis mellifera bee in the same region were investigated. There was found a remarkable quantitative and qualitative difference of flavonoids in propolis. These results indicate that the chemical composition of propolis was dependent on the variety of the bee.
