“…Diverse authors have related these structures with flavonoid compounds constituents of anthocyanins like cyanidin, pelargonidin or peonidin [9,21,27]. Other authors also reported their presence in tannins and lignins [28,29].…”

“…Analytical pyrolysis coupled to gas chromatography/mass spectrometry (PY-GC/MS), is a chromatographic variant used to analyze organic matter in short time and minimum sample preparation [8]. It allows the study of biopolymers or geopolimers, and naturals products like superior plant metabolites, from the analysis and interpretation of its pyrolysis products [9][10][11][12][13][14].…”

Characterization of a Natural Dye by Spectroscopic and Chromatographic Techniques

et al. 2012

Natural dyes have been extracted from both plants and animal to give color to textiles and handicrafts. This is the case of purple dye extracted from Justicia spicigera Schldt, an acanthaceae used as a color source since pre-Hispanic period in the Mayan area of Mexico and Central America. Spectroscopic (UV-Vis and FT-IR) and chromatographic (PY-GC/MS) techniques were employed in order to characterize some of their chemical properties. UV-VIS absorption spectra indicates a λ max peak at 581 nm, value associated to anthocyanins group under bathochromic effect. On the other hand, a structural characterization realized by FT-IR and Py-GC/MS indicated the presence of polar hydroxibenzoic acids and phenolic compounds which are characteristics of the molecular structure of anthocyanins.
