Perfis físico-químico e cromatográfico de amostras de própolis produzidas nas microrregiões de Franca (SP) e Passos (MG), Brasil

Abstract

Propolis is a generic term used to denominate the resinous and balsamic material collected from several vegetable sources and processed by the bees. Its chemical composition is complex and depends on the plant species of the region, seasonality, and genetic characteristics of the bees. Therefore, the aim of this work was to establish the physical and chemical quality controls of propolis samples from six different Brazilian micro regions of Franca (SP) and Passos (MG), as well as to verify the propolis quality for human consumption, and to select green propolis producing areas. The obtained results for the different analyses varied among the six different sites. The sites of Capetinga (MG) and Chave da Taquara (SP) produced green propolis during the whole collection period. Besides, the analyses of propolis samples from these sites indicated that they are satisfactory for human consumption based on the total flavonoids content, which varied between 1 and 2 % (w/w) and on the phenolic acids content, which varied between 4 and 8 % (w/w).
