摘要
[目的]为芳香精油的生产提供理论指导。[方法]分别从蓝桉、猴樟、香叶天竺葵、柠檬草、薄荷和柑橘中提取芳香精油,然后比较其出油率并采用灰色关联度法对6种精油的品质进行综合评价。[结果]蓝桉、猴樟、香叶天竺葵、柠檬草、薄荷和柑橘的平均出油率分别为0.86%、0.33%、0.24%、1.29%、1.27%和1.88%。精油颜色由亮到暗为:猴樟>薄荷>蓝桉>柠檬草>香叶天竺葵>柑橘;香味强弱为:柠檬草>香叶天竺葵>猴樟>蓝桉>薄荷>柑橘;香味持久性为:蓝桉>柑橘>香叶天竺葵>柠檬草>猴樟>薄荷;透明度为:猴樟>薄荷>柠檬草>香叶天竺葵>蓝桉>柑橘;香味好感度为:柠檬草>猴樟>香叶天竺葵>薄荷>柑橘>蓝桉。综合评价值最高的是柠檬草精油。[结论]该试验建立了精油品质的综合评价体系。
[ Objective ] The purpose was to provide theoretical direction for the production of aromatic essential oil. [ Method ] The aromatic essential oils were extracted from Eucalyptus globules, Cinnamomum bodinier, Pelargonium graveoleus, Cymbopogon citratus, Mentha haplocalyx and Citrus reticulata. Then their oil yielding rates were compared and the qualities of 6 essential oils were evaluated comprehensively by gray related degree method. [ Result] The average oil yielding rates of E. globules, C. bodinier, P. graveoleus, C. citratus, M. haplocalyx and C. reticulata were 0.86% , 0.33% , 0.24% , 1.29% , 1. ：27% and 1.88% resp. The colors of these essential oils from bright to dark were： C. bodinier 〉 M. haplocalyx 〉 E. globules 〉 C. citrates 〉 P. graveolens 〉 C. reticulata; their fragrance intensities were： C. citrates 〉 P. graveoleus 〉 C. bodinier 〉 E. globules 〉 M. haplocalyx 〉 C. reticulata ; their fragrance endurances were ： E. globules 〉 C. reticulate 〉 P. graveoleus 〉 C. citrates 〉 C. bodinier 〉 M. haplocalyx; their transparencies were： C. bodinicr 〉 M. haplocalyx 〉 C. citrates 〉 P. graveolens 〉 E. globules 〉 C. reticulata and the comfort degrees of their fragrance were： C. citrates 〉 C. bodinier 〉 P. graveoleus 〉 M. haplocalyx 〉 C. reticulate 〉 E. globules. The comprehensive evaluation value of essential soil from C. citrates was highest. [Conclusion] The comprehensive evaluation system for the quality of essential oils was established in this experiment.
