Resumo
Phytochemical study of Aloysia gratissima (Gillies & Hook.) Tronc. e Aloysia virgata
(Ruiz & Pav.) Pers., Verbenaceae, afforded fourteen compounds. The structures were established
using IR, 1D and 2D NMR and by comparison of its spectroscopic data to those of literature.
The antibacterial activity of the crude extract from the leaves and branches and the fractions from
the crude extract of A. virgata, besides the isolated compounds hoffmaniacetone, hoffmaniacetone
monoacetate, verbascoside and arenarioside were evaluated by means of bioautography and the
antiedematogenic activity was evaluated using induced ear oedema model to the crude extracts and
methanol fractions for A. gratissima and A. virgata.
