Antioxidant activity of Tagetes erecta essential oil

摘要

The essential oil from flowers of Tagetes erecta was evaluated for antioxidant activity in vitro using diphenyl-1-picrylhydrazyl (DPPH), thiocyanate, beta-carotene bleaching, free radical scavenging activity and oxidation of deoxyribose assay. The GC-MS analysis of the oil has resulted in the identification of 18 components; beta-caryophyllene, limonene, methyleugenol, (E)-ocimene, piperetone, piperitenone and ?-terpinolene were the main components.
