南果梨果皮挥发油成分的分析
【摘要】 用同时蒸馏萃取装置(SDE)提取南国梨果皮挥发油物质,测得南国梨果皮中挥发油的含量为0.61%,用GC/MS法从南国梨果皮挥发油中分离并确认出58 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百分含量,其中主要成分为依兰烯(25.46%),α-金合欢烯(16.11%),3,7,11-三甲基-1,3,6,10-十二碳四烯(9.15%),1,7,7-三甲基-双环[2.2.1]庚-2-醇(2.97%),7-甲基-4-亚甲基-1-(1-甲基乙基)-1,2,3,4,4a,5,6,8a-八氢化萘(2.63%),1H--2,4a,5,6,7,8-六氢苯并-3,5,5,9-四甲基环庚烯 (2.84%),1-甲基-4-(1-甲乙基)-1,4-环十六碳二烯(2.61%),石竹烯(2.08%),2-甲氧基-4-甲基-1-(1-甲乙基)苯 (2.07%),1-甲基-4-(1-甲乙基)苯 (2.04%),7,11-二甲基-3-亚甲基-1,6,10-十二碳三烯(1.72%),1-乙烯基-1-甲基-2-环己烷 (1.44%),加入其他成分,共占总检出量的91.35%。
【Abstract】 The essential oil of Pyrus Ussriensis Maxim nangguos peel was obtained by simultaneous distillation . The chemicalcomponents were separated and identified by GC/MS. The yield of essential oils of Pyrus Ussriensis Maxim nangguos peelwas 0.61% when extracted by simultaneous distillation. The experimental results confirmed the presence of 58 volatilecomponents when extracted by steam distillation. The experimental results demonstrate that the major components wereYlangene (25.46), a-Farnesene(16.11), 1,3,6,10-Dodecatetraene,3,7,11-trimethyl-(9.15), Bicyclo[2.2.1]heptan-2-ol,1,7,7-trimethyl-(2.97), aphthalene,1,2,3,4,4a,5,6,8a-octahydro-7-methyl-4-me-thylene-1-(1-methylethyl)(2.63),1,4-Cyclohexadiene,1-methyl-4-(1-methylethyl)(2.61), 1H-Ben-zocycloheptene,2,4a,5,6,7,8-hexahydro-3,5,5,9-tetramethyl-(2.84),Cartophyllene(2.08),Benzene,2-methoxy-4-methyl-l-(1-methylethyl)(2.07), Benzene,1-methyl-4-(1-methylethyl)(2.04), 1,6,10-Dodecatriene,7,11-dimethyl-3-methylene-(1.72), Cyclohexane,1-ethenyl-1-methyl-2,4-bis(1-methylethene) (1.44).
