The application of accelerated solvent extraction (ASE) technique to the extraction of extractable organic matters in source rocks with ASE 200 are discussed by comparing with traditional Soxhlet extraction technique. Based on analytical results of a mudstone sample from northeast China, the effects of dispersion ratio, extraction temperature and pressure conditions on the determination were discussed and the extraction conditions for extracting organic matters in source rocks with accelerated solvent extraction was optimized with dispersion ratio of 8∶3;extraction temperature of 110℃; extraction pressure of 10.3 MPa and heating time of 5 min. Under the optimized experimental condition, the satisfactory result was obtained with recovery rate of higher than 90% and precision of 2.6%RSD (n=10).  The results suggest that the accelerated solvent extraction technique can be applied to the extraction of organic matters in source rocks and as the pretreatment method for further organic geochemistry analysis.
