Resumo
Hydrolysable 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.
