Nonacosan-10-ol and <i>n</i>-Alkanes in Leaves of <i>Pinus pinaster</i>

In leaf cuticular wax of Pinus pinaster, content of nonacosan-10-ol is high (77.1% on average). n-Alkanes ranged from C 18 to C 35 with the most dominant C 29 (24.8%). The carbon preference index (CPI total ) ranged from 3.1 to 5.6 (4.0 on average), while the average chain length (ACL total ) ranged from 14.0 to 17.0 (14.8 on average). Long-chain n-alkanes ( n-C 25-35 ) strongly dominated (80.1%) over middle-chain ( n-C 21-24 = 18.9%) and short-chain ( n -C 18-20 = 0.9%) n-alkanes.
