Resumen:
Although the Acacia genus (Fabaceae) is represented by more than
1350 species distributed worldwide, there are few reports on the
chemical composition and biological properties of Argentinean
Acacia species. The presence of different flavonoids in the leaves
and stems has been reported. Acacia aroma is the most widely studied
species in this genus. Antioxidant, anti-inflammatory and antimicrobial
activity against multi-resistant human pathogenic bacteria
have been reported for A.aroma.
In this work we present the study of the phytochemical and biological
(antioxidant and antibacterial activity) screening from four
Argentinean Acacia species extracts (Acacia aroma, Acacia caven,
Acacia visco, Acacia praecox).
Phytochemical screening showed similar chemical patterns by
TLC for A. aroma and A. visco The presence of alkaloids was
discarded. TLC-autography (DPPH/ABTS) and bioautography
assay against Staphylococcus aureus methicillin-resistant were
performed. Antioxidant and antibacterial activities were demonstrated
in all preparations.
