PACHECO-COELLO, Franklin et al. Comparison of total phenolic compounds in Hibiscus sabdariffa L. Venezuela. Rev. colomb. cienc. quim. farm. [online]. 2019, vol.48, n.3, pp.521-527.  Epub Oct 29, 2020. ISSN 0034-7418.  https://doi.org/10.15446/rcciquifa.v48n3.84956.

The easy access and preparation of drinks based on Hibiscus sabdariffa L. represents an alternative in the treatment of chronic and degenerative diseases. The objective of the study was to compare the contraction of total phenols and flavonoids in chalices of Hibiscus sabdariffa L., of one commercial brand and another without sanitary permission. For the determination of total phenols, the Folin-Ciocalteu method and the Marinova colorimetric method for flavonoids were used. A statistically significant difference (p<0.05) was found in the concentration of total phenols and flavonoids. These results show that there are factors that condition the content of phenolic compounds, flavonoids in chalices and other bioactive compounds.

Keywords : Hibiscus sabdariffa L.; polyphenols; flavonoids.
