Sometimes, the preparation of a plant sample to GC analysis undergoes the stage of drying plant ex-tract from the solvent, and subsequently the repeated extraction of the dry residue in a different solvent. The purpose of this procedure is to separate the studied phenolic compounds from the matrix. This paper presents the results of the research into the effect of the type of solvent used in the proceeding (methanol, water, acetone, diethyl ether or chloroform) on the size of losses in the phenolic compounds during such a procedure. It has been noted that the greatest recovery appears in cases of methanol and acetone, whereas water may be the source of considerable losses in the compounds during the preparation of the plant sample for analysis.
