ResumoFLAVONOIDS AND TRITERPENES FROM Baccharis pseudotenuifolia -BIOACTIVITY ON Artemia salina.The phytochemical investigation of the chloroformic and methanolic extracts of the Baccharis pseudotenuifolia led to the isolation of triterpenes, steroids and flavonoids.From chloroformic extract were isolated oleanolic acid and α-spinasterol while from methanolic extract were isolated the flavonoids: hispidulin, naringenin, 3'-methoxy-luteolin, apigenin, kaempferol, eriodyctiol, aromadendrin, quercetin, 3'-methoxy-quercetin, quercetin-3-O-rhamnoside and quercetin-3-O-glucoside.The structure of these compounds were identified by IR, CG/MS, 1 H and 13 C NMR spectral analysis and comparison with literature.In addition, the extracts were evaluated by means of Brine Shrimp Lethality test and the highier activity was observed in the chloroformic extract.
