Application of 591-12-8. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 5-Methylfuran-2(3H)-one, is researched, Molecular C5H6O2, CAS is 591-12-8, about Cigar leaf differences from different producing areas based on aroma component analysis. Author is Yu, Hang; Liu, Yanting; Shang, Mengqi; Huang, Guangli; Fang, Yi; Lin, Lin; Qu, Yaling; Zuo, Qiaomei.
In order to investigate the leaf aroma chem. differences for cigar samples from different producing areas, 79 aroma components in 47 cigar samples from different countries were determined In addition, the differences in contents and odor activity values of aroma components among Cuban cigars, foreign non-Cuban cigars and Chinese cigars were compared by significance tests. The results showed that there were significant differences in the contents of 43 aroma components among the cigars from different producing areas, and the differences in the contents of α-curcumene and cedrol were the most significant. The contents of degradation products from chlorophyll and cembranoids in Cuban cigars were higher, those of phenylalanines and labdanums in foreign non-Cuban cigars and that of chlorophyll in Chinese cigars were lower. The 79 aroma components had higher odor activity values in fruit and flower flavors. Cuban cigars had higher odor activity values in herbal spices, fruit, flower and other flavors. Foreign non-Cuban cigars had lower odor activity values in plant, fruit, nut, flower and other flavors. The discriminant functions established by taking the contents of aroma components as variables can distinguish the producing areas of com. cigars.
