Abstract: Five nonvolatile organic acids and five major high fatty acids in 23 brands of domestic and foreign cigarettes were determined. The acids were derived into methyl esters by sulfuric acid-methanol(7:100, v/v)and extracted with dichloromethane, then analyzed by capillary gas chromatography. The results showed that, total levels of nonvolatile organic acids in foreign cigarettes (American blend) were rangedfrom 107.9 to 120.4 mg/g, with the mean value at 114.5mg/g; While those of domstic brands (Virginia blend) were ranged from 85.3 to 132.3 mg/g, and with the mean value at 109.6mg/g. The mean levels of oxalic, citric and malic acid in foreign cigarette were 28, 23.5 and 60 mg/g, respectively; while those of domestic brands were 21.8, 7.8 and 77.8mg/g, respectively. The situation of British style Virginia blend was at medium between above two type of cigarettes. Levels of high fatty acids in domestic cigarettes were higher than those in foreign cigarettes, while those of British style Virginia blend was also at the medium.
