Abstract The aim of this study was to evaluate the effect of freezing and atomization on bioactive compounds in cagaita fruit. The levels of total phenolics, total flavonoids, condensed tannins, vitamin C, β-carotene, the antioxidant potential assessed by DPPH and ABTS, sugar profile, and mineral profile were all evaluated. High levels of total polyphenols (881.95 mg/100 g), total flavonoids (42.93 mg/100 g) and condensed tannins (67.00 mg/100 g) were detected in atomized cagaita pulp. A higher content of vitamin C was found in fresh cagaita pulp (29.75 mg/100 g), compared to frozen pulp, or atomized pulp, which had levels of 24.64 mg/100 g and 20.38 mg/100 g, respectively. Atomized pulp had the highest antioxidant activity as assessed using the ABTS... |

Abstract Rutin has shown promising results in reducing various human diseases. However, many plants consumed in Brazil do not have their rutin content reported in the literature yet. More than eighty plants were analyzed using aqueous (popularly known as tea) and ethanolic extraction (employed in commercial rutin purification) by liquid chromatography. Rutin was found in 47 samples when ethanol extraction was used. Echinodorus grandiflorus had the highest content (14,878.7 mg 1000 g-1), followed by Sambucus nigra, Drimys winteri and Taraxacum officinale. In aqueous infusion, Echinodorus grandiflorus, Sambucus nigra, Drimys winteri and Ruta graveolens presented the highest levels of rutin, ranging from 15.5 to 29.7 mg of rutin in 300 mL of infusion from 2 g... |
