Themajor components of the Persea oils were sabinene (20.1%) and #beta#-caryophyllene (11.0%) in P.caerulea; #alpha#-phellandrene (24.9%) and #alpha#-terpiene (18.9%) in P.cinerascena; #alpha#-piene (20.5%), #beta#-pinene (16.9%) and germacrene D (24.3%) in P.donnell-smithii; sabinene (14.5%), #beta#-carophylene (11.3%), germacrene D (11.6%) and #gamma#-cadiene (18.6%) in P.lingue; #beta#-caryophyllene (6.5%) and #alpha#-humulene (7.3%) in P.longpipes; #apha#-terpinene (12.6%) and camphor (29.3%) in P.pachypoda; 1,8-cineole (33.7%) and camphor (10.2%) in P.palustris and #alpha#-pinene (14.8%), 1,8-cineole (12.3%), #gamma#-terpiene (12.8%) and germacrene D (12.2%) in P.skutchii. The oils of Beilschmiedia miersii and B. tarairie were found to be rich in #alpha#-terpiene (10.0%) and germacrene D (24.8%), and #alpha#-piene (17.8%) and germacrene D (6.6%), respectively. Litsea calicaris oil contained #delta#-cadinene (38.2%) and T-muurolol (28.8%) as main constituts. The main constituents of the oils of Nectandra umbrosa and N. salicina were methooxalen (24.5% and 30.1%) and indene (14.7% and 22.5%), respectively. The oils of Ocotea valeriana and O.botrantha were found to be rich in 1,4-cineole (19.6%) and (Z)-anethole (13.4%), and #delta#-elemene (11.2%), #beta#-caryophyllene (13.4%) and germacrene D (35.2%), respectively. 收起
