The present study aimed to investigate the composition and potential anticancer activities of vital oils obtained from two species, myrrh and frankincense, by hydrodistillation. Making use of gas chromatography-mass spectrometry (GC-MS), 76 and 99 components were identified inside the myrrh and frankincense essential oils, respectively, with the most abundant components, 2-Cyclohexen-1-one, 4-ethynyl-4-hydroxy-3,5,5-trimethyl- and n-Octylacetate, accounting for 12.01 and 34.66 , respectively. The effects with the two critical oils, independently and as a mixture, on 5 tumor cell lines, MCF-7, HS-1, HepG2, HeLa and A549, have been investigated applying the MTT assay. The results indicated that the MCF-7 and HS-1 cell lines showed improved sensitivity for the myrrh and frankincense important oils compared with all the remaining cell lines. Furthermore, the anticancer effects of myrrh have been markedly enhanced compared with these of frankincense, on the other hand, no substantial synergistic effects had been identified. The flow cytometry outcomes indicated that apoptosis may be a FP Purity & Documentation significant contributor for the biological efficacy of MCF7 cells. Introduction Commiphora myrrha has a yellow oleo-gum resin that exists in its stem and is applied worldwide for the production of myrrh, specifically in China and Egypt. The constituents of myrrh, include volatile oil (2-8 ), resin (23-40 ), gum (40-60 ) and bitter principles (10-25 ). Previous research have shown thatmyrrh exhibits cytotoxic, analgesic, antiinflammatory, anticancer, antiparasitic and hypolipidemic activities (1-4). Frankincense is definitely an aromatic resin obtained from trees in the genus Boswellia and has been hypothesized to exhibit several overall health supporting properties, including the therapy of rheumatoid arthritis and antiinflammatory, antibacterial, antifungal and anticancer activities (5-8). Frankincense oil is ready by the steam distillation of frankincense gum resin and is frequently made use of in aromatherapy practices. Based on earlier studies, the constituents of frankincense oil differ as outlined by the climate, harvest situations and geogra.
