螺旋压榨—水蒸气蒸馏提取木姜子精油和种子油

Screw pressing-steam distillation for extraction of Litsea pungens essential oil and Seed oil

  • 摘要: 采用螺旋压榨—水蒸气蒸馏法提取木姜子精油和种子油。实验考察了压榨温度对精油与种子油得率的影响。结果表明:木姜子精油和种子油的最高得率,分别在压榨温度120℃和140℃。经 GC-MS 分析,精油主要成分为 α-柠檬醛、β-柠檬醛和 D-柠檬烯;种子油中饱和脂肪酸占比最高,以月桂酸和癸酸为主,且压榨温度对各主要成分含量均有一定影响。

     

    Abstract: Essential oil and seed oil were extracted from Litsea pungens using a screw pressing-steam distillation method. The study investigated the effect of pressing temperature on the yield of essential oil and seed oil. Results indicated that the highest yields of Litsea pungens essential oil and seed oil were achieved at pressing temperatures of 120°C and 140°C, respectively. According to GC-MS analysis, the main components of the essential oil were α-citral, β-citral, and D-limonene. Saturated fatty acids accounted for the highest proportion in the seed oil, mainly lauric acid and capric acid, and the pressing temperature had a certain effect on the contents of the main components.
