There were performed quantitative analyses of the 5,3'-dihydroxy-4',6,7-trimethoxyflavone and 5-hidroxi-3',4',6,7-tetrametoxiflavone in native and cultivated plants of Baccharis trimera. Six harvests were done in both dry and humid seasons. The flavone 5,3'-dihydroxy-4',6,7-trimethoxyflavone showed more content in plants harvested in humid season. There were no differences when comparing cultivated and native plants from both seasons. The flavone 5-hydroxy-3',4',6,7-tetramethoxyflavone showed more content in native than cultivated plants in humid season. And there was no difference in the dry season when comparing native and cultivated plants.
