Chinese. 对四川攀西地区烤烟成熟过程中下部、中部叶片类胡萝卜素类色素及其降解产物进行定量分析。结果表明，攀西地区烤烟叶片类胡萝卜素类色素含量随成熟时期推进而逐渐降低。攀西地区烤烟下部叶片类胡萝卜素类降解香气物质于成熟-完熟时期增加较快，而中部叶片类胡萝卜素类色素降解香气物质于未熟-成熟期间随成熟推进而增加，成熟-完熟期含量有所降低。其中大马酮随成熟时期的推进而增大；二氢猕猴桃内酯随成熟时期的推进呈逐渐降低趋势，成熟前期含量较高；β-紫罗兰酮成熟过程中含量较低，且完熟期、烤后样均检测不到含量；巨豆三烯酮类致香物随成熟时期推进而呈整体增长趋势。

The quantitative determination results on cartenoids and aromatic components of the cartenoids in flue-cured tobacco leaves from Panxi region, Sichuan Province at different mature periods. The results showed that the contents of cartenoids decreased gradully during the mature periods of flue-cured tobacco leaves in Panxi region. The contents of aromatic components of the cartenoids in the lugs of flue-cured tobacco leaves increased gradully during the end of mature period, but there were not in cutters. The contents of damascenone increased gradully during the mature period of flue-cured tobacco leaves from Panxi region, but the contents of dihydroactinolide decreased gradully. The content of β-inone was little during the mature period of flue-cured tobacco leaves and it was non at the end. The contents of megastigmatrienones increased during the mature period.
