摘要:
以超临界CO2提取的辣椒籽油为原料,采用溶液进样和顶空-固相微萃取方式进样,结合GC-MS分析,同时鉴定出主要化学成分和挥发性成分。研究结果表明:超临界CO2提取辣椒籽油中共鉴定出62种成分,主要化学成分为亚油酸、油酸、棕榈酸、辣椒碱、二氢辣椒碱、硬脂酸等,顶空-固相微萃取进样法鉴定出的主要挥发性成分为亚油酸、棕榈酸、顺-2,4a,5,6,7,8,9,9-八氢-3,5,5,-三甲-9-亚甲基-1H-苯并环庚烯、油酸、硬脂酸、异戊酸己酯、异草蒿脑、邻羟基苯甲酸甲酯等。
Abstract:
Paprika seed oil extracted by supercritical carbon-dioxide extraction(SCE) was used for material.GC-MS with Solution injection and headspace-solid phase micro-extraction(HS-SPME) was applied to the analysis of chemical composition of paprika seed oil. And the main chemical composition especially the volatile compounds were identified. Research results showed that a total of 62 components were identified in the paprika seed oil,which were linoleic acid,oleic acid,palmitic acid,capsaicin,dihydrocapsaicin,stearic acid,etc. In HS-SPEM experiments,the main volatile compounds were linoleic acid,palmitic acid,(4a S)-2,4a,5,6,7,8,9,9a-Octahydro-3,5,5-trimethyl-9-methylene-1H-benzocycloheptene,following it were oleic acid,stearic acid,hexyl 2-methylbutyrate,cis-anethol,2-carbomethoxyphenol,etc.
