摘 要:为明确恩施白肋烟中性致香成分组分和含量及与国外白肋烟的异同,以恩施不同产区及美国、马拉维白肋烟样品为材料,采用气质联用仪对样品的中性致香成分含量进行分析测定,结果表明:恩施白肋烟中性致香成分总量及各组分含量在产地之间存在一定差异,其中香叶基丙酮、苯甲醛、糠醇等单一致香成分含量的变异较大。以巨豆三烯酮为代表的类胡萝卜素类降解产物含量以美国烟叶最高,恩施次之,马拉维最低;恩施白肋烟苯丙氨酸类、棕色化反应产物含量均高于美国和马拉维,而西柏三烯的主要降解产物茄酮则低于国外烟叶。聚类分析将供试样品分为3类,80%的恩施样点与美国同属一类,表明恩施白肋烟中性致香成分含量与美国具有较高的相似性。In order to clarify the differences in the constituent and contents of neutral aroma components between Enshi and for -eign burley tobacco, we used the samples of burley tobacco from Enshi , the United States, and Malawi as test materials, and ana-lyzed and tested the contents of neutral aroma components in these samples by adopting GC -MS.The results indicated that there were certain differences in both the total content of neutral aroma components as well as the content of each constituent in burley to -bacco among different producing areas of Enshi , especially the differences in the contents of geranylacetone , benzaldehyde and furfu-ryl alcohol were greater .The tobacco leaf samples from the United States had the highest content of carotenoids , which were repre-sented by megastigmatrienone , followed by those from Enshi and Malawi in order .The contents of phenylalanines and browning reac-tion products in Enshi burley tobacco were higher than those in American and Malawi burley tobacco .The content of solanone in En-shi burley tobacco was lower than that in foreign burley tobacco .The results of cluster analysis showed that all tobacco leaf samples could be divided into three groups , and the American samples and 80%Enshi samples were classified into the same group , indica-ting that the contents of neutral aroma components in Enshi burley tobacco were highly similar to those in American burley tobacco .
