摘要
以德州乐陵金丝小枣为原料,用两种方法提取了枣精油,研究了各种因素对产率的影响。结果表明,用乙醇提取枣精油的产率较高,其最佳工艺条件为料液比1∶4、浸提时间20min、浸提温度78℃、水蒸气蒸馏时间10min。
Ziziphus jujube cv. Jinsixiaozao produced in Dezhoulaoling was used as raw material, the essential oils from jujube was extracted using two methods, the influence of various factors on the yield was studied. The results show that the yield of essential oils is higher using ethanol as solvent, and optimal parameters for extracting the essential oils from jujube are as following： the ratio of raw material weight （g） to solvent volume （mL）1：4, extracting time 20 min, extracting temperature 78 ℃ and steam distUtation time 10 min.
