Abstract

The research explored the chemical characteristics of essential oils (EOs) extracted from the peels of four citrus fruits grown in northeastern Peru (lime, sweet lemon, mandarin and orange). The essential oils were extracted by hydrodistillation using a green solvent, and subsequently, their physicochemical profile, bioactive, heat capacity, and RAMAN mapping were determined; in addition, the volatile composition was determined by gas chromatography (GC-MS), and the main phenols by liquid chromatography (UHPLC). The results evidenced that sweet lemon and mandarin essential oils had higher antioxidant activity (1592.38 and 1216.13 μmol TE/g) and total phenolic content (680.78 and 420.28 mg GAE/g). In contrast, sweet lemon peel essential oil had the highest total flavonoid content (23.18 mg QE/g). D-limonene was the most abundant aromatic compound in orange (>67 %), mandarin (>70 %), and sweet lemon (>72 %) EOs; however, in the lime, it was the lowest (37 %). The most abundant component was the cyclobutane, 1,2-bis(1-methylethylethylenyl)-, trans- (32 %).

利用绿色溶剂探索柑橘皮精油的化学特性。

这项研究探讨了从秘鲁东北部种植的四种柑橘（青柠、甜柠檬、柑橘和橙子）果皮中提取的精油（EOs）的化学特性。使用绿色溶剂通过水蒸馏法萃取精油，随后测定了精油的理化性质、生物活性、热容量和 RAMAN 图谱；此外，还使用气相色谱法（GC-MS）测定了挥发性成分，使用液相色谱法（UHPLC）测定了主要酚类物质。结果表明，甜柠檬和柑橘精油具有较高的抗氧化活性（1592.38 和 1216.13 μmol TE/g）和总酚含量（680.78 和 420.28 mg GAE/g）。相比之下，甜柠檬皮精油的总黄酮含量最高（23.18 毫克 QE/克）。在橙子（>67%）、柑橘（>70%）和甜柠檬（>72%）精油中，D-柠檬烯是含量最高的芳香化合物；而在酸橙中，D-柠檬烯含量最低（37%）。含量最高的成分是环丁烷，1,2-双（1-甲基乙基乙烯基）-反式（32%）。
