Revista Brasileira de Plantas Medicinais, Botucatu, v. 13, n. 1, p. 85-89, 2011.1516-0572e- 1983-084Xhttp://repositorio.bc.ufg.br/handle/ri/16480Hydrolysable tannins, total phenols and flavonoids in Eugenia uniflora leaves were monthly analysed for one year. The results were correlated with climate conditions (rainfall, humidity, cloudiness and mean temperature) through chemometric methods. Principal component analysis revealed high levels of hydrolysable tannins in the rainy season, whereas flavonoids were mainly produced in the dry season. These facts suggest that climatic changes may be one of the factors affecting phenol levels in Eugenia uniflora.engAcesso AbertoEugenia unifloraPitangaHydrolysable tanninsFlavonoidsSeasonal variationEugenia unifloraPitangueiraTaninos hidrolisáveisFlavonoidesVariação sazonalArtigo
