Constituíntes fenólicos polares de Schinus terebinthifolius Raddi (Anacardiaceae)

the etoh extract from the leaves of schinus terebinthifolius showed anti-radicalar potential in the dpph test. it was partitioned between n-buoh:h2o (1:1) and these two phases were also evaluated for anti-radicalar activity. the active n-buoh phase was partitioned between etoac:h2o (1:1) and the active etoac phase was submitted to chromatographic procedures to afford five active phenolic compounds: ethyl gallate, methyl gallate, quercitrin, myricetrin and myricetin. the structures of these compounds were established by nmr spectral data analysis.
