| 摘 要： | 为研究不同海拔对雪茄烟致香前体物质的影响,选取四川达州地区3个不同海拔高度种植的雪茄烟中部叶与上部叶为材料,研究分析主要致香前体物质的含量差异。结果表明,随着海拔的升高,中部叶与上部叶多酚类物质呈现逐渐升高的趋势,表现为高海拔多酚类物质含量整体上显著高于中、低海拔。色素类物质随海拔升高表现不一,叶绿素含量随海拔升高呈逐渐降低的趋势,叶黄素和β-胡萝卜素含量呈逐渐增加的趋势,中部叶与上部叶变化规律一致。与中、低海拔相比,高海拔上部叶有机酸总量分别增加了20.43%和29.80%,中部叶与上部叶保持一样的趋势。上、中部烟叶的总生物碱含量均随其种植海拔高度的上升呈显著下降的趋势（P<0.05）,上部叶和中部叶高、中、低海拔生物碱总含量分别为8.75%、7.00%及4.12%。根据灰色关联度分析,海拔对多酚类物质影响较大,色素次之,生物碱最小。

| Abstract: | In order to study the effects of different altitudes on the aroma precursors of cigars, the middle and upper leaves of cigars planted at three different altitudes in Dazhou, Sichuan province were selected to analyze the differences of main aroma precursors content. The results showed that, with the increase of altitude, the content of polyphenols in middle and upper leaves increased gradually. The content of polyphenols in high altitude was significantly higher than that in medium and low altitude on the whole. Pigment substances showed different performance with the increase of altitude, chlorophyll content decreased gradually with the increase of altitude, on the contrary, the content of xanthophyll and β-carotene increased gradually, and the change law of middle and upper leaves were the same. The total amount of organic acids of upper leaves at high altitude increased by 20.43% and 29.80%, respectively, compared with medium and low altitude, and the treads of middle leaves was the same as the upper leaves. The total alkaloid content of upper and middle tobacco leaves decreased significantly with the increase of altitude (P<0.05). The average alkaloid content from high, medium and low altitude of middle and upper leaves was 8.75%, 7.00% and 4.12%, respectively. According to the grey correlation analysis, altitude had a greater impact on polyphenols, followed by pigments and alkaloids. |
