Of the species Werneria apiculata and Werneria marcida S. F. Blake of the Asteracae family it can be extracted and identified: reducing sugars (glucose, levulose) guns, tannins, steroids, fenolic compunds, flanvonoids, alcaloids. lt has been found in W. Marcida low concentration of the same principies.The biological assays of the Artemia Salina Leach, both species present biodinamic activity. W apiculata presents greater bronco-dilatador activity and antiinflamatory than W Marcida.The terapeutic activity of these species is due the presence of flavonoids, that were obteined as the mayor constituyents that we think participate in a pronounded way in the total activity of the drug.

An experimental research is carried out ain to evaluate the analgesic effect of the lyophilized extract from the Bíxa orellana L leaves, that was administrated by oral via at a 100 and 150 mgkg-l doses. Hot- plate and abdominal contortions methods were applied in the research development. The selected animals were albino male mice from the stock Batb/c-53 at a corporal weight steemed in 23.67 + 1.03g. Paracetamol and indometacina were employed as positive controls at a 400 mgkg-l and 10 mgkg-l doses respectively.According to the obtained results, it concludes that the Bixa orellana L., presents analgesical activity at a peripheric level in the abdominal contortions model, that was directly proportional to the doses under our experimental conditions. .
