Although many papers have been devoted to the study of coriander fruits’ aromatic pattern, many differences show up according not only to the provenance of seeds, but also to the analytical methods chosen. In our work, samples from onecoriander small-seeded biotype have been analysed, verifying the differences between (1) the oil extracted by means of a Soxhlet apparatus, (2) the same oil sampled by means of HS-SPME and (3) the HS-SPME on the roughly ground seeds, all analysed by direct injection in the GC-MS. The volatile composition detected by means of HS-SPME on oil resembles tightly that performed on Soxhlet extract. With respect to the direct injection, the HS-SPME shows a higher sensitivity towards the less heavy and therefore more volatile compounds. The HS-SPME on roughly ground seeds is able to highlight the more volatile compound as limonene, α-terpinene and in particular the E-2-decenal that in hot extraction is irremediably lost.
