Résumé
The antimycobacterial activity of Scutia buxifolia Reissek, Rhamnaceae, leaves extracts and fractions were evaluated for the first time. Four compounds were identified, flavonoids (quercetin and quercitrin) and phenolic acids (gallic and caffeic acids) and quantified by HPLC-DAD. Promising anti-Mycobacterium smegmatis activity was observed with ethyl acetate extract (MIC 312.50 mu g/mL) and their fractions (MIC values ranging from 78.12 to above 312.50 mu g/mL). The fractions III and VI of S. buxifolia leaves showed a high level of activity against M. smegmatis (MIC 78.12 and 156.25 mu g/mL, respectively), M. tuberculosis (MIC 156.25 mu g/mL) and M. avium (MIC 312.50 mu g/mL), whereas to the other fractions the values varied from 312.50 to 1250.00 mu g/mL against these strains. The better MIC result was associated with two fractions that contain bigger amounts of quercetin, quercitrin, gallic and caffeic acids. The results provided evidence that the studied plants fractions might be potential sources of new antimicrobial drug.
