ABSTRACT=The chemical composition and CIELAB colour parameters of oil from three aguaje morphotypes (Mauritia flexuosa L.f.) extracted by supercritical carbon dioxide was investigated. By chromatography (HPLC and GC), spectrometry (UV/vis), and digital image colorimetry (digital camera), carotenoids, tocopherols, tocotrienols, fatty acids, total polyphenols, and CIELAB colour space were analyzed. These findings showed that the oil obtained from morphotype 3 was superior in several analytes, while morphotype 2 and morphotype 1 showed very close profiles. The chromatic parameters (L*, a*, b*, and C*ab) were quite different except for the hue angle (hab) which showed some similarity. The most similar chemical components in the oils of the three morphotypes were stigmasterol, β-sitosterol, palmitic acid and oleic acid. Aguaje oil is an interesting resource that stands out for its high content of carotenoids. All three morphotypes may be suitable for potential commercial applications.
