【 摘 要 】

Popularly known as aster-arbustiva, margarida-de-são-miguel and monte-cassino, Aster lanceolatus is an ornamental plant. Having the knowledge that there is no studies on the biological activity of this species, this work aimed to check the antibacterial and antifungal activities. The ethanol extracts of the flowers and of the stems with leaves were used. For the antibacterial activity eight pathogenic bacteria were submitted to the diffusion test in gel and minimal inhibitory concentration. The activity of the ethanolic extract of the flowers has been demonstrated against Streptococcus pyogenes in diffusion in gel and the activity of the ethanol extract of the stems and leaves against Salmonella typhimurium and Streptococcus pyogenes in minimal inhibitory concentration. For the antifungal activity, three pathogenic yeasts have been used in the micelial growth tests in plates and direct bioautography. In the micelial growth tests in plates the inhibition of Fusarium oxysporum has been verified and in the direct bioautography, inhibition of the Cylindrocladium spathulatum. The results indicated a new research source, the ornamental plants. These can be the source of chemicals capable of serving as prototypes for new therapeutic agents and for sanitary treatment of medicinal plants.
