- Abstract:
- ... This study investigated the antioxidant activity of Cuphea glutinosa (CG) and its effect on Na⁺, K⁺-ATPase from cardiac muscle. The ethanolic extract showed higher antioxidant capacity compared to aqueous and ethyl acetate fraction. Ethyl acetate fraction showed β-sitosterol-3-O-β-glucoside, kaempferol, quercetin, isoquercetin, gallic acid methyl ester, and gallic acid. The ethanolic extract also ...

- Abstract:
- ... In order to produce carotenoids with antioxidant potential from the wild yeast Rhodotorula mucilaginosa, Sporidiobolus pararoseus and Pichia fermentans, isolated from the ecosystem of Escudo Sul-Rio Grandense (Brazil), cultivations were performed with: raw glycerol and corn steep liquor (M1), sugar cane molasses and corn steep liquor (M2) and Yeast Malt (YM) broth. Production of β-carotene more th ...
