In this study, infused teas and soluble extract of H. sabdariffa L. from three brands resold in Palmas/TO, were used to evaluate the levels of phenols, flavonoids, tannins (total and condensed) and monomeric anthocyanins, as well as antioxidant power and sugars (reducing and non-reducing). For the evaluations, the Folin-Ciocalteu colorimetric method was used for total phenols and flavonoids, total tannins by casein complexation and condensates by the butanol-HCL method. The quantification of monomeric anthocyanins was performed by differential pH method and antioxidant power with ferricyanide, free radical sequestration by 2,2-diphenyl-1picril-hydrazine and sugars with 3-5 dinitrosalicylic acid. Data were analyzed using descriptive statisti...
