Description
Summary:	This pioneering study is the first to explore the extraction of Calycolpus goetheanus using supercritical carbon dioxide (scCO2), novel approach to harnessing the bioactive potential of this Amazonian species. By examining extractions under varying temperatures (35 and 45 °C) and pressures (150, 250, and 350 bar), the research not only evaluates the yields but also uncovers significant differences in chemical composition and antioxidant activity compared to traditional hydrodistillation. Notably, the highest yield (2.11 ± 0.07 %) was achieved under 45 °C and 350 bar conditions, where n-heneicosane (34.26 %) was the dominant compound, alongside δ-cadinene, α-terpineol, and other important terpenes and fatty alcohols. The scCO2 extracts demonstrated superior antioxidant activity compared to hydrodistillation, highlighting the method's ability to preserve and concentrate bioactive compounds. This research advances the field by showcasing scCO2 as a greener and more efficient extraction technique, with potential applications in pharmaceuticals, cosmetics, and nutraceuticals, opening new pathways for the sustainable exploitation of Amazonian biodiversity.
