摘要：

为揭示质体色素与烤烟香气物质含量的关系，探明郴州地区香气风格的形成原因及烟叶质量特色。以‘云烟87’、‘K326’、‘云烟203’和‘KRK26’4个品种C3F等级烟叶为材料，采用高效液相色谱法、气质联用法对烟叶质体色素及其降解致香物质含量进行测定。研究结果表明，不同品种烤烟烟叶叶绿素、类胡萝卜素及其降解产物含量存在显著差异，质体色素总量以‘云烟203’最高，‘云烟87’最低，‘云烟87’经调制后香气协调，‘K326’和‘KRK26’具有较好的香气品质，‘云烟203’的质量相对较差。质体色素的降解产物中新植二烯所占的比例最高，品种间表现为：‘云烟87’>‘KRK26’>‘K326’>‘云烟203’。

Abstract:

In order to reveal the relationship between the material content of plastid pigments and neutral volatile aroma components in flue-cured tobacco, with ‘Yun 87’, ‘K326’, ‘Yun 203’ and ‘KRK26’ as experimental material, the C3F grade tobacco leaves was used in the analysis of plastid pigments and neutral volatile aroma components by instrument of high performance liquid chromatography GC-MS. The results showed that the content of chlorophyll, carotenoids and their degradation products existed significant differences in different varieties. The content of total plastid pigments in ‘Yun 203’ and ‘Yun 87’ were the highest. The aroma quality of ‘YUN87’ after brewage was coordination. The aroma quality of ‘K326 ’and ‘KRK26’ were better than ‘Yun 203’. The highest proportion of degradation products of the plastid pigment was neophytadiene, the result manifest as follows: ‘Yun 87’> ‘KRK26’> ‘K326’> ‘Yun 203’.
