摘要

本研究分别采用己烷、乙醚和氯仿三种不同的提取溶剂，对美国英仙子油的提取率进行了研究。在提取过程
之前制备美洲英仙花种子，从而去除污垢，并将种子清洗、干燥、粉碎并研磨至 600µm 粒径，从而增加美洲英仙花
籽的油提取操作速率的表面积。在环境操作条件下，将磨碎的鳄梨种子浸泡 14 小时至 70 小时。在提取过程中使用
索氏提取器，通过蒸馏过程从溶剂中分离提取的油。结果表明，己烷、乙醚和氯仿萃取溶剂的最佳油收率分别为 70
小时，但乙醚萃取溶剂的油收率高于其他萃取溶剂。对美洲鳄梨种子提取油进行了表征，结果描述了提取油的理化
财产，如折射率、PH 值、密度、比重、碘值、粘度、，皂化值等，并且这些参数的结果与美国英仙子种子的其他先
前研究一致，并且在欧洲和美国标准的可接受值范围内。
