Determination of free and glucosidically-bound volatiles in plants. Two case studies: L-menthol in peppermint (Mentha x piperita L.) and eugenol in clove (Syzygium aromaticum (L.) Merr. & L.M.Perry)

The quali-quantitative analysis of L-menthol and eugenol in peppermint aerial parts and cloves has been obtained by the use of high-concentration-capacity sample preparation techniques (SBSE, and HS-SPME and in-solution SPME) in combination with GC-FID/MS.
