摘 要:对云南产蒜头果油用硫酸-甲醇法酯化,以气相色谱-质谱-计算机联用仪进行了分析。共分离出17种成分,鉴定了其中的7种成分,分别为棕榈酸(质量分数(下同)1.50%)、油酸(21.54%)、二十碳烯-11-酸(7.04%)、芥酸(18.29%)、二十二烷酸(1.33%)、二十四碳烯-15-酸(40.92%)、二十四烷酸(2.14%),占总质量的92.76%;未被鉴定的成分占总质量的7.24%。
Abstract:Fatty
acids in the Malania oleifera oil of Yunnan were esterified by sulfuric
acid-methanol and analyzed by GC-MS. Seventeen
components were separated and seven acids as methylesters were
identified and determined. They were hexadecanoic acid(1.50%),9c-octadecenoic
acid(21.54%),11c-eicosenoic
acid (7.04%),13c-docosenoic
acid (18.29%),docosanoic
acid (1.33%),15c-tetracosenoic
acid (40.92%),tetracosanoic
acid (2.14%).There
were 7.24%
components unidentified. |
