摘　　要：以干燥黄瓜籽为原料,采用索氏溶剂萃取法提取黄瓜籽油,采用单因素试验,以黄瓜籽油的收率为评价指标,进行了索氏提取法萃取黄瓜籽油的工艺研究,考察了萃取溶剂种类、萃取温度、萃取时间和黄瓜籽质量浓度对油收率的影响。索氏提取法最优化工艺条件:萃取溶剂为正己烷,萃取温度是68.5℃,萃取时间8 h,黄瓜籽质量浓度为0.071 g/mL,油收率达40.38%。The cucumber seed oil was obtained by Soxhlet extraction with the seed as the raw material.Soxhlet extraction of oils from cucumber-seed was studied with single factor test,and the yield of cucumber-seed oils was the evaluation index.The influences of extracting solvent,extracting temperature,extracting time,the rate of raw material,and solvent on the yield of cucumber-seed oils were investigated respectively.The optimal conditions of Soxhlet method were obtained： extracting temperature is 68.5 ℃,extracting time is 8 h,the mass concentration of cucumber-seed oil is 0.071 g/mL,optimal extracting solvent is n-hexane.The oil yield reaches 40.38% under the optimal conditions.
