摘要:

Forty-seven compounds have been characterized by GC/MS and relative retention times in 64 samples ofMelaleuca quinquenerviaoils collected on 21 different trees during three seasons. Statistical analyses reveals the presence of two chemotypes. If chemotype I is already known (1, 8-cineole type), the other one (chemotype II) is characterized by a high content in viridiflorol (48%).

摘要:

The essential oils ofThymus cariensisHub.-Mor. et Jalas andThymus haussknechtiiVelen were examined by GC and GC/MS. The major components in T.cariensisoil were borneol (13.42%), 1, 8-cineole (12.65%) and α-pinene (12.15%), while in T.haussknechtiioil they were linalool (19.91%) and borneol (10.35%). Both oils were almost devoid of phenols.

摘要:

The essential oils of fresh leaves and semi-ripe fruits ofPistacia lentiscusL., the evergreen shrubby tree widely distributed on the mountains of Galilee, Gilead, Carmel and Judea were investigated by capillary GC/MS. Leaf and fruit oils were found to be similar in composition. The leaf oil was found to be rich in α-terpineol (13.02%), ethyl hexadecanoate (10.36%), ethyl linolenate (11.30%) and some unidentified sesquiterpene alcohols (15.90%), while the fruit oil was found to be rich in terpinen-4-ol (13.07%), α-terpineol (13.62%) and some unidentified sesquiterpene alcohols (13.20%). The leaf and fruit oils differ substantially from Mastic oils of other Mediterranean origins primarily by their very low monoterpene content.
