The antioxidant effects of the hydro-alcoholic guaraná extract (Paullinia cupana var. sorbilis Mart.) on nitric oxide (NO) and other compounds generated from the degradation of sodium nitroprusside (SNP) in an embryonic fibroblast culture (NIH-3T3 cells) were evaluated. The guaraná bioactive compounds were initially determined by high-performance liquid chromatography: caffeine=12.240 mg/g, theobromine=6.733 mg/g and total catechins=4.336 mg/g. Cells were exposed to 10 μM SNP during a 6 h… CONTINUE READING
