Correlation analysis between the major phenolic compounds in flue-cured tobacco MS with smoking quality

The effect of origin,part and variety at major phenolic compounds of mainstream smoke,and the relativity of contents of major phenolic compounds in mainstream smoke with the smoking quality were investigated.The results showed that the origin,position and variety were huge to contents of these compounds,including diphenol,resorcinol,catechol,phenol,m-cresol,p-cresol,and o-cresol,CV15%,the maximum approximately remained at 80%,in which,the position was the key determinant,the biggest CV was 63.5%;the contents of these seven compounds had a complicated relativities,which had the significant positive correlation with one another.The results of bivariate and factor analysis showed that the smoking quality were influenced by these seven compounds.With the increase of comprehensive factor score,the scores of physiological and taste strength would increase,while moist degree and irritancy would reduce,and the flavor of aroma would tend to heavy,but hardly change the aftertaste,offensive odor and aroma.
