摘  要:
Eleven kinds of polybasic acids and higher fatty acids of 39 samples of flue-cured tobacco in Yunnan and 2 overseas samples in 2004 were classified by the method of cluster analysis.The results indicated that the 41 samples could be classified into 3 classes: the samples from Kunming,Baoshan,Lincang and Zhaotong(except for Weixin) belonged to type 1;the samples from Yuxi(except for Huaning),Dali,Simao and overseas belonged to type 2;the samples from Qujing belonged to type 3;the samples from Chuxiong,Honghe and Wenshan belonged to type 1 and type 2 respectively.The content of malic acid,citric and linoleic acid was secondary in type 1;the content of malic and citric acid was lower,and the content of linoleic acid was higher in type 2;the content of malic acid was the highest,the content of citric acid was higher,and the content of linoleic acid was lower in type 3.
