In the present study, a sooting flame was formed in a reduced-pressure combustion chamber with a premixed flame of methane and oxygen for the surrounding flame and premixed flame of toluene and oxygen for the center flame. We inserted the sampling probe and collected the soot like substances from the toluene-oxygen flame to analyze contents of fullerenes and PAHs at the early stage of the fullerene or PAH formation reactions. The experimental results showed the contents of Acenaphthene, Phenanthrene, Fluoranthene and Phyrene were relatively high in the soot like substances collected through the sampling probe. We considered that at the early stage of the formation mechanism of fullerenes or soot the chemical species of these Acenaphthene, Phenanthrene, Fluoranthene and Phyrene were dominant in the present experiments. The contents of C_<60> in the total fullerenes at the early stage of the combustion reaction were larger than those collected at the main filter and the contents of C_<70> at the early stage of the combustion reaction were smaller than those collected at the main filter.
