| Abstract: | 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. |
