摘要: 用同时蒸馏萃取装置(SDE)提取南果梨果肉挥发油物质,测得南果梨果肉中挥发油的产率为0.17%,用GC/MS法从南果梨果肉挥发油中分离并确认出26 种化学成分,用峰面积归一法通过G1710BA化学站数据处理系统得出各化学成分在挥发油中的相对百分含量,其中主要成分为邻苯二甲酸双(2-乙基己基)酯(29.4%),依兰烯(23.47%),α-金合欢烯(8.4%),9-十八烯酸乙酯(6.13%),2,6-二甲基-6-(4-甲基-3-丙烯基)双环[3.1.1]庚烷-2-烯(4.4%),亚油酸乙酯(2.41%),加入其他成分,共占总检出量的86.56%。

Abstract: The essential oil of flesh from Nanguoli pear was obtained by simultaneous distillation . The chemical componentswere separated and identified by GC/MS. The yield of essential oils of flesh .from Nanguoli pear. was 0.17% when extracted bysimultaneous distillation. The experimental results confirmed the presence of 26 volatile components when extracted by steamdistillation. The experimental results demonstrate that the major components were Bis(2-ethylhexyl) phthalate (29.4%), Ylangene(23.47%), α-Farnesene(8.4%), 9-Octadecenoic acid, ethylester(6.13%), Bicyclo[3.1.1]hept-2-ene,2,6-dimethyl-6-(4-methy,l-3-pentenyl) (4.4%), Linoleic acid ethyl ester (2.41%).
