Abstract:

The perylene of some samples from certain basins of China is examed by means of GC/MS/computer system.The perylene fractions,which contain mainly the compounds of molecular weight 252,and are devoid of those less than 252, were separated from the sample exiracts by means of column chromatograpny and thin layer chromatography. Mass spectrogram of the perylene isolated by glass capillary gas chromatography in our researchs are identical with the standard one.
