Essential Oil Composition of Four Magnoliaceae Species Cultivated in Vietnam

摘要

The chemical constituents of hydrodistilled essential oils from the leaves of four Magnoliaceae species were examined. The main compounds in Manglietia fordiana oils were 6-cadinene (18.0%), (E)-nerolidol (16.7%), a-copaene (12.8%), a-selinene (9.1%), and limonene (8.3%); in Manglietia conifera oils they were B-caryophyllene (29.9%), a-humulene (7.4%), (E)-nerolidol (6.3%), and caryophyllene oxide (5.5%). The major constituents of Michelia mediocris oil were (E)-nerolidol (36.4%), 6-cadinene (10.9%), and B-selinene (7.2%), while in Michelia tonkinensis they were a-pinene (40.3%), (3-phellandrene (7.6%), B-pinene (7.4%), and bicyclogermacrene (7.3%).
