摘要
目的比较两种不同提取方法所得的黑松松塔挥发油的挥发性化学成分。方法分别采用超临界CO2流体萃取(SFE)和水蒸气蒸馏(SD)提取黑松松塔的挥发油。运用气相色谱-质谱联用法分离和分析两挥发油的挥发性化学成分。结果超临界CO2流体萃取法提取的挥发油共鉴定出43种成分,占挥发油总成分的60.78%;水蒸气蒸馏法提取的挥发油共鉴定出37种成分,占挥发油总成分的86.16%;结论采用两种方法提取黑松松塔挥发油组分与含量差别较大,且SFE法的提取率低于SD法。
Objective To compare the chemical constituents of volatile oil from the pinecone of Pinus thunbergii Parl. by two extraction methods. Methods The volatile oil was extracted from the pinecone of Pinus thunbergii Parl. by supercritical fluid extraction （SFE） and steam distillation （SD） methods, respectively. The chemical constituents of volatile oil were separated and analyzed by gas chromatography-mass spectrometry （GC-MS）. Results Forty-three kinds of chemical components of the pinecone of Pinus thunbergii Parl. were identified by SFE and 37 components by SD, which accounted for 60.78% and 86.16% of the total volatile oil, respectively. Conclusion The chemical constituents and their contents of volatile oil extracted by two methods were different significantly, and the extraction yield of SFE method is lower than that of SD method.
