Abstract This study was aimed to extract oil from Asiasarum heterotropoides using supercritical carbon dioxide (Sc-CO2) with and without ethanol as co-solvent and to compare the results with conventional extraction solvents. A total of 27 major volatile organic compounds (VOCs) were identified among them eucarvone, 3-carene, safrole, methyleugenol, and camphene were found to be the highest. The solvent Sc-CO2 + ethanol at 250 bar and 50 °C was found to be the best condition to get high yield of oil with 3.54 ± 0.21%. The extracted oil showed 100% of deodorant efficiency within 30 min of reaction with an artificially manufactured odorant.

使用超临界二氧化碳和有机溶剂从亚洲沙龙中回收的精油的理化特性和除臭活性

摘要 本研究旨在使用超临界二氧化碳 (Sc-CO2) 以乙醇为助溶剂和不以乙醇为共溶剂从异形细辛提取油，并将结果与​​常规提取溶剂进行比较。共鉴定出 27 种主要挥发性有机化合物 (VOC)，其中丁香酮、3-蒎烯、黄樟素、甲基丁香酚和莰烯含量最高。发现溶剂 Sc-CO2 + 乙醇在 250 bar 和 50 °C 下是获得高油收率的最佳条件，为 3.54 ± 0.21%。提取的油在与人工制造的气味剂反应 30 分钟内显示出 100% 的除臭效率。
