Constituíntes fenólicos polares de Schinus terebinthifolius Raddi (Anacardiaceae)

Abstract: Recebido em 24/3/06; aceito em 17/7/06; publicado na web em 10/1/07 POLAR PHENOLIC CONSTITUENTS FROM 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:H 2 O (1:1) and these two phases were also evaluated for anti-radicalar activity. The active n-BuOH phase was partitioned between EtOAc:H 2 O (1:1) and the active EtOAc phase was submitted to chromatographic procedures to… Show more

“…All compounds isolated from the BuOH phase (1-5) were subjected to evaluation of antiradical potential by spraying a solution of 2.0 mg/mL of DPPH in methanol in a TLC plate (SiO 2 ). After 5 minutes, were observed strong yellow spots on violet background, suggesting that compounds 1-5 are responsible for antiradical potential observed in the crude extract/phases, as previously reported (Coutinho et al, 2010;Ceruks et al, 2007;Rosa et al, 2010).…”

“…After evaporation of the solvent (about 5 min), the antiradical potential, comparatively with positive control α-tocopherol (1.0 mg/mL in CHCl 3 ), was observed by the appearance of yellow spots on violet background, according to that described in the literature (Ceruks et al, 2007).…”

“…A investigação fitoquímica do extrato polar das folhas de S. terebinthifolius resultou no isolamento de diversos derivados fenólicos, com ênfase nos derivados do ácido gálico além de flavonoides glicosilados, de acordo com o observado em trabalho anterior com essa espécie. 9 No entanto, é interessante observar que não foi verificada a ocorrência de derivados da miricetina, um flavonol tri-hidroxilado no anel B 9 formado a partir dos mesmos precursores que geram o ácido gálico, mas a presença de flavonoides de ocorrência menos restrita (5 e 6), cujos derivados aglicônicos (quercetina e canferol) foram isolados anteriormente dos galhos de S. terebinthifolius. 8 Uma vez que o extrato em EtOH mostrou potencial frente a diferentes linhagens tumorais humanas in vitro, esse foi submetido a um processo de partição líquido/líquido sendo que a fase obtida em AcOEt apresentou atividade.…”

“…8 Derivados fenólicos, tais como os galatos de metila e etila além de flavonoides (miricetina, miricetrina e quercitrina) foram isolados do extrato polar das folhas, cuja ocorrência foi associada à elevada atividade antirradicalar. 9 Adicionalmente, a análise química das cascas do tronco mostrou a existência de antraquinonas, xantonas e esteroides livres. 10 Os óleos essenciais de folhas, flores e frutos de S. terebinthifolius de diferentes regiões foram previamente analisados, os quais se mostraram compostos basicamente por derivados mono e sesquiterpênicos.…”
