A total of 23 constituents represe nting 95.8% in the oil of V. amygdalina were identified by GC-MS. The oil is composed of a mixture of mono and sesquiterpine components. The major essential oil contents of Veronia amygdalina identified were 1, 8-cineole (23.2%) and muuralol (17.1%). The oil also contained a- pinene (5.4%), carvone (5.3%), and caryophyllene (6.4%), humulene (6.0% farnesol (5.5 %) A comparative study of the oil constituents indicated that there are significant variations.
