Chemical Composition and Cytotoxic Activity of Leaves Essential Oil from Mangifera indica var. coquinho (Anacardiaceae)

The volatile composition of Mangifera indica var. coquinho has been studied. The essential oils were obtained by hydrodistillation in a modified Clevenger-type apparatus, and their analyses were performed by GC-FID and GC/MS. A total of 19 different compounds were identified. Sesquiterpene hydrocarbons were shown to be the main group of constituents of all taxa. The main constituents of the oil were alpha-gurjunene (24.0%), beta-selinene (24.0%), beta-caryophyllene (11.2%), alpha-humulene (7.2%), caryophyllene oxide (5.5%) and humulene epoxide (2.4%). The cytotoxic activity of the oil was more pronounced than antioxidant and antimicrobial activities.
