Relationship Between TSNAs and Nitrate,Nitrite,Nicotine in Yunnan Oriental Tobacco

    Abstract
  • The nitrate,nitrite,nicotine and TSNAs in lamina and vein of Yunnan oriental tobacco were determined and the resultant data were analyzed correlatively.The results showed that:1) the TSNAs contents in lamina and vein were higher in lower grade leaves;2) TSNAs content in lamina was higher than that in vein;and 3) TSNAs contents in lamina and vein correlated extremely significantly positively with nicotine,significantly positively with nitrite,and positively with nitrate.
