【摘要】 采用超临界CO2流体萃取技术(SFE-CO2)提取了采集于湖南省凤凰县、泸溪县、古丈县和吉首市的白背叶种子的种仁油,种仁油甲酯化后,运用气相色谱—质谱联用技术(GC-MS)测定其化学成分。结果表明,四个采样点的白背叶种仁油共同含有油酸、棕榈酸、亚油酸、硬脂酸和杜鹃花酸,它们的相对含量依次减少。其中前四种为白背叶种仁油的主要组成成分,它们的总和在种仁油中所占的比例是凤凰98.92%、古丈96.67%、吉首94.84%、泸溪94.58%。更多还原

【Abstract】 Kernel oil of Mallotus apelta,obtained by supercritical CO2 fluit extraction(SFE-CO2)from the seed of the tree grown at Fenghuang County,Luxi County,Guzhang County and Jishou City of Hunan Province in China,were analyzed by gas chromatography-mass spectrometry(GC-MS)after esterification.The results revealed that oleic acid,palmitic acid,linoleic acid,stearic acid and azelaic acid were the five common components that existed in the kernel oils collected from the four sampling points,with their relative contents reduced in order.The former four components are major compositions of kernel oil,which comprising 98.92% of the oil from Fenghuang County,96.67% from Guzhang County,94.84% from Jishou City and 94.58% from Luxi County.更多还原
