摘　　要：为研究河南不同植烟区和不同品种浓香型烟叶叶片不同区位石油醚提取物的含量差异，以河南3个植烟区4个品种18个浓香型初烤烟叶为材料，分切成10段后，分析了烟叶叶片不同区位间石油醚提取物的含量。结果表明：①180个不同区位叶片石油醚提取物含量范围在1．91％～6．82％之间；②不同区位间石油醚提取物含量差异性为极显著，从叶尖到叶基石油醚提取物含量呈现降低的趋势；③不同地区烟叶叶片石油醚提取物含量存在显著差异，即：郏县含量最高，襄县次之，卢氏县最低；不同品种的石油醚提取物含量也存在显著差异，即：豫烟10〉中烟100〉豫烟11〉云烟87。进一步通过系统聚类分析，以烟叶的石油醚提取物含量为评价指标，可将浓香型烟叶叶片连续分为三段进行后续加工。In order to investigate the differences of petroleum ether extract contents between different portions of robust flavor style flue-cured tobacco leaves of various cultivars from different areas, eighteen leaf samples of four flue-cured tobacco cultivars from three regions in Henan were collected, each leaf was cut into 10 portions, and the contents of petroleum ether extracts in every leaf portion were determined. The results showed that： I） The contents of petroleum ether extracts in the 180 leaf portions ranged from 1.91% to 6.82%. 2） The contents of petroleum ether extracts in different portions extremely significantly differed with a decreasing trend from leaf tip to base area. 3） The contents of petroleum ether extracts in leaves of different cultivars from different areas were significantly different, the counties in the order of leaf petroleum ether extract content were Jiaxian〉 Xiangxian〉 Lushi, and the cultivars in the same order were Yuyan 10 〉 Zhongyan 100 〉 Yuyan 11 〉 Yunyan 87. 4） The results of system cluster analysis indicated that the leaves could be cut into three consecutive portions from the point of petroleum ether extract content and processed in different ways.
