Abstract: To investigate the extraction conditions of essential oil from fresh branches-leaf sections of Cunninghamia lanceolata by hydrodistillation, single factor method was used to analyze the effects of sample crushing method, liquid-solid ratio, distillation time and NaCl concentration on the oil yield. The results showed that the oil yield of fresh branch-leaf sections of C. lanceolata could reach a high level of 0.086% when the sample was crushed by the chaff cutter method, the liquid-solid ratio was set to 8:1, the distillation time was 6 h and without the addition of NaCl. After that, the essential oil components were analyzed by gas chromatography-mass spectrometry (GC-MS). A total of 48 compounds were identified, including 29 sesquiterpenoids and 10 monoterpenoids, which accounted for 88.22% and 7.53% of the total mass, respectively.

摘要: 为探明水蒸馏法提取杉木Cunninghamia lanceolata鲜枝叶精油的提取条件,采用单因素法分析样品粉碎方式、液料比、蒸馏时间和NaCl浓度等对出油率的影响。结果表明,采用切草机法粉碎样品,液料比为8:1,蒸馏6 h且不添加NaCl处理的杉木鲜枝叶出油率较高,为0.086%。采用气相色谱质谱(GC-MS)联用仪对精油组分进行解析,共鉴定出48种化合物,其中主要包含29种倍半萜类化合物以及10种单萜类化合物,其质量分别占总质量的88.22%、7.53%。
