GUZMAN-FIGUEROA, María del Pilar et al. New Pyranoanthocyanins Synthesized from Roselle ( Hibiscus sabdariffa L. ) Anthocyanins. J. Mex. Chem. Soc [online]. 2016, vol.60, n.1, pp.13-18. ISSN 1870-249X.

Six new pyranoanthocyanins were synthesized through the reaction between dephinidin-3-sambubioside and cyanidin-3-sambubioside, extracted from roselle calyxes, with 4-vinylphenol, acetone and 2-butanone. The reaction products were characterized by liquid chromatography coupled to mass spectrometry (HPLC-TOF-MS), ultraviolet-visible spectroscopy (UV/Vis) and high-performance liquid chromatography. Those new pigments belong to the families of pinotins and methylpyranoanthocyanins and show a hypsochromic shift, which results in a more orange colour compared to the red hue of the original anthocyanins. Therefore, these compounds could be used to obtain new colorants more stable against certain factors such as pH.

Palabras llave : pyranoanthocyanins; roselle; 4-vinylphenol; acetone; pinotins; methylpyranoanthocyanins.
