Maffei, M. | Scannerini, S.
Seasonal variations in fatty acid (FA) composition were studied in developing peppermint (Mentha piperita) leaves. FA were analysed from the non-polar fraction of the lipid extracts. FA from free FA, diacylglycerols and triacylglycerols were analysed before and during full bloom. The qualitative FA composition was dominated by palmitate (16:0), linoleate (18:2) and linolenate (18:3). Leaves of 10, 20, 40 and 60 mm in length were analysed. Leaves of 10 mm were found to possess the highest content of 16:0, 18:2 and 18:3 before and during full bloom. A decreasing trend in both total and unsaturated FA was observed with leaf development. The results were correlated with monoterpene metabolism and are discussed further.
