Assessment of Tobacco Specific Nitrosamines in Tobacco Genotypes Peiguo Guo1, a, Yanshi Xia1, Ronghua Li1, Yonghua Lü2, Miaowen Qiu3, Weichai Zhao3 and Yiwen Yu1 1College of Life Sciences, Guangzhou University, Guangzhou 510006, China 2 Guangdong Tobacco Monopoly Administration, Guangzhou 510610, China 3 Nanxiong Research Institute of Guangdong Tobacco Co., Nanxiong, Guangdong 512400, China aemail: guopg@yahoo.com or guopg@gzhu.edu.cn Keywords: Tobacco; Germplasm; Tobacco-Specific Nitrosamines (TSNAs).
For this purpose, 8 genotypes (include burley, sun-cured and flue-cured tobacco) were selected as materials, the TSNAs contents of uncured and cured leaves were assessed with LC-MS/MS.
Material and Method Tobacco Material Eight genotypes with three types of tobacco listed in table 1 were kindly provided by Nanxiong Research Institute of Guangdong Tobacco Co.
Acknowledgments This study was supported by the grants from the State Tobacco Monopoly Administration and China National Tobacco Corporation (2010[99]18), the Science and Technology Planning of Guangdong Tobacco Monopoly Administration (200903).
