| Résumé : | The fresh- and dried-leaf oils and the fresh-leaf concentrate of Peperomia serpens were obtained by hydrodistilla-tion and SPME, and analyzed by GC and GC/MS. The main compounds identifed in the hydrodistilled fresh-leaf oil were (Z)-nerolidol acetate (42.9%) and (E)-nerolidol (31.3%). The major constituents found in the SPME fresh-leaf headspace were α-humulene (49.1%) and β-caryophyllene (35.1%). The hydrodistilled dried-leaf oil was dominated by (Z)-nerolidol acetate (36.6%) and (E)-nerolidol (29.1%). It seems that the hydrolysis of α-humulene, identifed only in the SPME fresh-leaf headspace, was responsible by the appearance of (E)-nerolidol in the fresh- and dried-leaf oils, followed by isomerization and acetylation to produce (Z)-nerolidol acetate, being all the process heat provoked. |
