AUTHOR(S): Thuc Dinh Ngoc and Mai Vu Thi Ha
ABSTRACT:The chemical composition of the essential oils from leaves and stems of Vernonia amygdalina were obtained by hydrodisitillation and analyzed by gas chromatography-mass spectrometry (GC-MS). In this study, total of 31 and 22 compounds were identified, accounting for 94.92% and 73.74% of the total essential oil contents from Vernonia amygdalina leaves and stems, respectively. The main components found in leaves oil include caryophyllene oxide (29.51%), β-caryophyllene (19.95%), α-humulene (8.50%), humulene epoxide II (5.73%), β-selinene (4.25%), limonene (3.43%), α-selinene (3.28%) and spathulenol (3.11%). While the major components found in stems oil were caryophyllene oxide (36.28%), humulene epoxide II (10.63%), β-caryophyllene (4.37%), spathulenol (2.77%), E-caryophyllene (2.72%), β-selinene (2.53%), α-humulene (2.21%) and β-cis-elemene (2.09%). This is the first study on the chemical composition of the leaves and stems essential oils of Vernonia amygdalina collected in Thanh Hoa province, Vietnam.
