An analytical method for Nitro-substituted nitrogen containing cyclic compounds (NNCCs) by HPLC was systematically investigated for combustion gases from heavy oil. HPLC conditions for the determinations of NNCCs were studied with standard NNCCs, and the following conditions were found to be optimum for the analysis of NNCCs in the combustion gases of heavy oil; stationary phase : Shim-pack ODS-II (4.6mm i.d.×250mm), mobile phase : acetonitrile-water, flow rate : 0.7ml/minute, column temperature : 40℃, detector : Photo diode array UV-VIS detector (190∿ 900nm). NNCCs containing soot is the combustion gases from 100ml of heavy oil were collected on a glass filter of low volume sampler. After the NNCCs in the collection glass filter was supersonically extracted with methanol. The extract was concentrated to 2ml under reduced pressure at 20℃. NNCCs were separated with an acetonitrile-water mixture effluent by HPLE, and determinated by the comparison of retention times and UV spectra. 4-nitroindole and 2-nitroacridine were detected and identified in the combustion gases of heavy oil, and their concentrations were 8.5 and 3.6μg, respectively, for examined samples NNCCs of standard substances used in this study are as follows : 1. 3-nitropyrrole, 2. 8-nitroquinoline, 3. 6-nitroquinoline, 4. 5-nitroquinoline, 5. 4-nitroindole, 6. 2-nitroacridien, 7. 3-nitrocarbazole.
