RORIZ, C. Lobo et al. Gomphrena globosa L. as a source of natural pigments: characterization in betacyanins. Rev. de Ciências Agrárias [online]. 2017, vol.40, n.spe, pp.191-200. ISSN 0871-018X. https://doi.org/10.19084/RCA16235.
In this paper, it is described the betacyanins composition (class of betalain with red-purple pigmentation) of globe amaranth (Gomphrena globosa L.) in order to highlight this plant as an alternative source of natural dyes. The analysis was performed by high-performance liquid chromatography coupled with a photodiode array detector and mass spectrometry with electron spray ionization (HPLC-PDA-MS/ESI) after extraction with different solvents (infusion with water and maceration with water: methanol, 80:20, v/v).
