Acta Agriculturae Jiangxi(2012)
Abstract
采用同时蒸馏萃取装置和气相色谱/质谱联用仪(GC/MS),测定和分析了昭通烤烟3个主栽品种(C3F)烟梗中的8类共77种致香成分含量,结果表明:(1)3个品种(C3F)烟梗在致香成分总量上无显著差异,但在检出的8类致香成分中,除醇类和酯类外,有6类存在显著或极显著差异,占检出类别的75%。(2)在酮类和酚类成分上,云87极显著高于红大和K326,红大与K326无显著差异;在醛类成分上,红大显著低于云87和K326,云87与K326无显著差异;在酸类成分上,红大显著高于云87,而K326与红大、云87均无显著差异;在杂环类成分上,红大显著高于K326,而云87与红大、K326均无显著差异;在烯烃类成分上,K326显著高于红大,而云87与K326、红大均无显著差异。
