Abstract:

For providing the bases and establishing the foundation for the analysis of the aroma components of Chinese orchid to research the aroma components of Cymbidium ensifolium. The aroma components of Cymbidium ensifolium ‘Xiao Tao Hong’ were detected by SPME/GC-MS. The suitable condition was gained that was optimized pretreatment of the sample by orthogonal design of experiment and the analysis of range. The optimized condition of pretreatment sample involved weight of fresh flower was 0.6 g, extraction time was 60 min, handle scale was 4 cm and desorption temperature was 250℃.The condition was used in the research for obtaining the credible statistics. There were 35 kinds of components was identified in total and the relative contents was 99.499%. The ester material was the most, about 83.155%, and it was believed that the ester material was the main matter of Cymbidium ensifolium ‘Xiao Tao Hong’. The others were alcohols 10.710%, silane 1.944%, terpenes 1.713%, acids 1.659% and keton 0.319%. The consequences indicated that the major components were Methyl jasmonate (21.563%); Methyl epijasmonate (19.628%) and farnesol (10.710%).
