以湖北清江流域8个烤烟主产区24个烟叶样品为供试材料,对烤烟12种类胡萝卜素降解产物进行了相关分析和因子分析,并利用因子得分进行综合评价.结果表明,烤烟类胡萝卜素降解产物间存在显著或极显著的相关性.相关系数矩阵前3个特征根的累计贡献率已达85.05%.由类胡萝卜素降解产物的因子载荷矩阵得到3个公因子,即巨豆三烯酮类因子、大马酮类因子和庚烯类因子.因子分析法综合评价的结果与评吸结果基本一致,为用化学指标评价烤烟品质提供了新方法.

By correlation analysis and factor analysis,totally 24 of tobacco samples from 8 tobacco growing counties of Hubei Province were analyzed with data from 12 carotenoid degradation products in flue-cured tobacco leaves.A comprehensive evaluation was carried out by using the factor scores.The obtained results indicated that the contents of the carotenoid degradation products were positively or highly positively correlated with that of the others.The contribution rate of first-three characteristic roots reached 85.05%.Three main factors from the carotenoid degradation products were obtained,namely the megastigmatrienone factor,damascone factor,heptene factor.The comprehensive evaluation result of factor analysis was essentially identical with sensory evaluation result,which could be used in assessing the quality of flue-cured tobacco leaves and also could provide scientific reference to flue-cured tobacco products.
