摘要
采用了主成分分析、夹角余弦等方法，分析了国产烤烟烟叶与津巴布韦、巴西烤烟挥发性香味物质的相似性和差异。结果表明：香气物质的总量以巴西最高，其次是津巴布韦，国产烤烟要略低一些，云南烤烟在酮类物质的总量上与津巴布韦烤烟差异较大。就整体相似性而言，国内烤烟中湖南烤烟和云南烤烟与津巴布韦烤烟较相似，而湖北烤烟与巴西烤烟较接近。
Similarity and difference of volatile aromatic compounds （VAC） in flue-cured tobaccos from China, Zimbabwei and Brazil was carried out using angel cosine and principal component analysis. Results showed that total amount of VAC was the highest in tobacco from Brazil, followed by Zimbabwei and domestic tobacco. There was big difference between Yunnan and Zimbabwei flue-cured tobacco in total amount of VAC. Similarity and principal component analysis indicated that of all the domestic flue-cured tobacco, tobacco from Yunnan and Hunan were similar to that from Zimbabwei, while tobacco from Hubei was similar to that from Brazil.
