Absolute Oil Extraction and Components Analyses of Irises for Perfume Production of Different Varieties and Sources
In order to select the suitable material source for industrial development,we collected 4 root materials of different iris cultivars and sources,extracted absolute oil,compared oil yield rate and aroma,and the compositions and contents were analyzed by GC-MS and internal standard quantification method.The results showed that the absolute oil yield of Iris pallida from Italian and Zhejiang were lower,which were 1.35%and 0.93%,respectively.The total amount of components detected was higher,which were 192.05,210.97 μg/mg dry material,respectively.The content of α-irone and γ-irone were higher,the ratio was better,and the characteristic aroma was obvious.The absolute oil yields of Iris pallida and Iris germanica from Yunnan were higher,7.04%and 3.96%,respectively.The total amount of components detected was lower,130.07,106.16 μg/mg dry material,respectively.The contents of α-irone and γ-irone were lower,and the characteristic aroma was lighter or not obvious.According to the comprehensive analysis,Iris pallida from Italian and Zhejiang are more suitable material sources.
