          Abstract

          Objetivou-se com esta pesquisa analisar a própolis produzida por abelhas Apis mellifera L. no Estado da Paraíba, colhida pelo método de tela plástica, determinando-se a composição físico-química e a atividade antimicrobiana conforme o período de colheita das amostras. Para a determinação físico-química, foram avaliados os teores de umidade, cinzas, resíduos insolúveis, cera, sólidos solúveis, fenóis, flavonóides e índice de oxidação. Para o estudo da atividade antimicrobiana, foram utilizados os microrganismos Candida albicans e Staphylococcus aureus. O teor de umidade, os resíduos insolúveis, as cinzas, os sólidos solúveis, os fenóis, os flavonóides e o índice de oxidação das amostras testadas apresentaram uma variação de 1,0 a 8,6%; 23,5 a 40,4%; 1,1 a 3,3%; 32,0 a 62,5%; 1,0 a 8,1%; 0,04-0,5% e de 14 a 29 segundos, respectivamente. Os extratos etanólicos de própolis não apresentaram inibição ao crescimento dos patógenos testados. Observou-se, também, que a própolis colhida em diferentes épocas do ano, assim como a própolis oriunda de diferentes colméias, apresentaram diferentes valores para a composição bromatológica e bioativa, tendo a própolis amostrada nos períodos de maior precipitação os melhores valores para compostos bioativos.

          This study was aimed at analysing the propolis produced in beehive of Apis mellifera L. bee in the state of Paraiba - Brazil. Propolis was collected by the method of plastic screen, determining the physical-chemical composition and antimicrobial activity according to the period of collection of the samples. For the physical-chemical determination, it was assessed the humidity, ashes, insoluble residues, wax, soluble solids, phenols, flavonoids and oxidation index. To study the antimicrobial activity, microorganisms Candida albicans and Staphylococcus aureus were used. The humidity contents, insoluble residues, ashes, soluble solids, phenols, flavonids and index of oxidation of the tested propolis varied from 1.03 to 8.58%; 23.47 to 40.38%; 1.13 to 3.25%; 31.97 to 62.54%; 1.01 to 8.13%; 0.045-0.52% and from 14 to 29 seconds, respectively. None of the etanol extracts of propolis inhibited the growth of bacteria pathogenic. It was also observed that the propolis collected in different times of the year, as well as propolis originated from of different beehives, showed different chemical composition and bioactive and that propolis sampled in periods of greater precipitation had better values of bioactive compounds.

              Chemical composition and antibacterial activity of Brazilian propolis.

              Four samples of Brazilian propolis were investigated by GC/MS of different fractions. 32 volatile compounds, (10 of them new for propolis), as well as 12 more polar compounds (one of them new for propolis) were identified. Antibacterial activity was found in some propolis fractions.
