Nonacosan-10-ol and n-Alkanes in Leaves of Pinus pinaster

Abstract

In leaf cuticular wax of Pinus pinaster, content of nonacosan-10-ol is high (77.1% on average). n-Alkanes ranged from C18 to C35 with the most dominant C29 (24.8%). The carbon preference index (CPItotal) ranged from 3.1 to 5.6 (4.0 on average), while the average chain length (ACLtotal) ranged from 14.0 to 17.0 (14.8 on average). Long-chain n-alkanes (n-C25-35) strongly dominated (80.1%) over middle-chain (n-C21-24 = 18.9%) and short-chain (n-C18-20 = 0.9%) n-alkanes.
