摘  要：
通过分析香榧假种皮提取物的成分,为香榧假种皮开发利用提供技术方法。本研究采用水蒸气蒸馏法、有机溶剂提取法、超临界CO2萃取法等3种方法对香榧假种皮中的物质进行了提取,并采用GC-MS对提取物成分进行了分析。结果表明:(1)超临界CO2萃取得到的香榧假种皮提取物得率最高(22.12±0.09%),有机溶剂提取法次之(18.28±0.14%),水蒸气蒸馏法最低(2.17±0.02%)。(2)分别鉴定了超临界CO2萃取法、有机溶剂提取法、水蒸气蒸馏法得到的香榧假种皮提取物中51、70、86种成分。超临界CO2萃取法和有机溶剂提取法得到的提取物主要成分均为沸点较高的二萜类物质;水蒸气蒸馏法得到的提取物主要成分是低沸点的倍半萜类和单萜类物质,是植物挥发油的主要成分。因此可根据需求采用不同方法对香榧假种皮进行加工利用。

摘  要：
To analyse the chemical compositions of the essential from Torreya grandis cv. Merrillii Aril.,and prove the value of Torreya grandis cv. Merrillii and promote its industrial development. The hydro-distillation,solvent extraction and supercritical carbon dioxide extraction methods have been used to compare for their chemical constituents from Torreya grandis cv. Merrillii Aril. The chemical compositions of the extract were analyzed by GC-MS. The results showed that the supercritical carbon dioxide extraction method had the highest yield of the extract( 22. 12 ± 0. 09%),followed by the solvent extraction( 18. 28 ± 0. 14%),the hydro-distillation had the lowest yield of the extract( 2. 17 ±0. 02%). The major constituents of the volatile oil obtained by hydrodistillation were monoterpenoids and diterpenoids.The major constituents of the extract obtained by solvent extraction and supercritical carbon dioxide extraction were diterpenoids,which was the main compositions of the essential oil. Thus the different methods can be used for the extraction of essentialoil from Torreya grandis cv. Merrillii Aril.
