GC/MS analysis of the leaf oil ofCryptomeria japonicaD. Don obtained from Reunion allowed us to identify more than 70 compounds thanks to our SPECMA data bank. Among the volatiles, monoterpene hydrocarbons (45%), monoterpene alcohols (10%), monoterpene esters (2%), sesquiterpenes (25%) and diterpenes (12%) have been found. The presence of a moderate amount of α-kaurene (10%) and its 16-hydroxylated derivative (0.6%) was noted. The composition of theC. japonicafrom Reunion was found to be similar to that originating from Japan. Unidentified sesquiterpene and diterpene derivatives require further attention.
