The proximal composition, amino acid, carbohydrate, and volatile profiles of caferana () seeds flour were here assessed. Seeds were also subjected to the following extraction processes: one with pressurized ethanol (PLE) and two with ethanol + supercritical CO mixture at different temperatures and pressures (SC1 and SC2). Extracts were characterized in terms of caffeine, total phenolic, and δ-lactam. The characterization of caferana seed and its extracts is unprecedented in terms of carbohydrate and volatiles profiles, besides the δ-lactam identification/isolation. SC2 extract exhibited a higher caffeine (9.3 mg/g) and δ-lactam (29.4 mg/g) content, whereas the PLE extract contained a higher total phenolic amount (3.0 mgGAE/g). Caferana is regionally associated to protective effects on mental health. Its byproduct (seed) revealed to be a promising source of bioactive compounds, and a potential raw material of nutritive extracts and flours that can be incorporated into pharmaceutical, nutraceutical, cosmetic, and food products.
本文评估了卡费拉纳（）种子粉的近端成分、氨基酸、碳水化合物和挥发性成分。种子还进行了以下提取过程：一次用加压乙醇（PLE）提取，两次用乙醇+超临界CO₂混合物在不同温度和压力下提取（SC1和SC2）。提取物在咖啡因、总酚和δ-内酰胺方面进行了表征。除了δ-内酰胺的鉴定/分离外，卡费拉纳种子及其提取物在碳水化合物和挥发性成分方面的表征是前所未有的。SC2提取物表现出较高的咖啡因（9.3毫克/克）和δ-内酰胺（29.4毫克/克）含量，而PLE提取物含有较高的总酚量（3.0毫克GAE/克）。卡费拉纳在当地与对心理健康的保护作用有关。其副产品（种子）被证明是生物活性化合物的一个有前途的来源，以及营养提取物和面粉的潜在原料，可纳入药品、营养保健品、化妆品和食品中。
