Abstract


The paper compares the fatty matter recovered from cotton when applying one extraction with dichloromethane or two successive extractions (the first with dichloromethane and the second one with methanol, more polar) and the time required for the operation when using SOXTEC® System HT2 or the usual Soxhlet. Results showed that it is convenient to make successive extractions of 1 hr and 30 minutes, respectively, with SOXTEC®. The fatty matter extracted was homogeneous, with independence of its origin. Before the analysis of pesticides, samples should be purified by gas chromatography (ECD or MS).
