Popis: | A new technique to extract lipid biomarkers (n-alkanes and n-methyl-ketones) from forest litters and soils using the accelerated solvent extraction (ASE) method was developed. The maximum output of n-alkanes and n-methyl-ketones was obtained by sequential extraction using the chloroform : methanol mixture [3 : 1 (vol)] in the first two extraction cycles and chloroform in the subsequent two cycles. The extraction has been carried out at the temperature of 100°С, pressure of 10.3 MPa, and static extraction time of 5 min. The repeated chloroform treatment by ASE was shown to increase the output of long-chain n-alkanes and n-methyl-ketones. |
