Abstract

Beta-myrcene [or myrcene (1,6-Octadiene, 7-methyl-3-methylene-)] and the essential oils containing this monoterpene have been widely used in cosmetics, detergents, and soaps, and as flavoring additives for food and beverages. Due to the potentially high level of human exposure to beta-myrcene, and absence of studies involving its genotoxicity in human cells, the aim of this study was to investigate the cytotoxic and genotoxic potential of this terpenoid in non-metabolizing cells (leukocytes) and liver metabolizing cells (HepG2/C3A cells). Prior to the genotoxic assessment by the comet and micronucleus (MN) assays, a range of beta-myrcene concentrations was tested in a preliminary MTT assay. Regarding the MTT assay, the results showed cytotoxic effects for leukocytes at 250 µg/ml and higher concentrations, while for HepG2/C3A cells, absence of cytotoxicity was noted relative to all tested concentrations (after 24 hr exposure). Thus, the concentrations of 2.5, 10, 25, 50, and 100 µg/ml for leukocytes, and 2.5, 100, and 1000 µg/ml for HepG2/C3A cells were selected for subsequent assays. Genotoxicity evaluation demonstrated significant DNA damage in the comet assay and significant chromosomal abnormalities including nucleoplasmic b...Continue Reading
