The present study aimed to investigate the composition and prospective anticancer activities of important oils obtained from two species, myrrh and frankincense, by hydrodistillation. Utilizing gas chromatography-mass spectrometry (GC-MS), 76 and 99 elements have been identified inside the myrrh and frankincense important oils, respectively, together with the most abundant elements, 2-Cyclohexen-1-one, 4-ethynyl-4-hydroxy-3,five,5-trimethyl- and n-Octylacetate, accounting for 12.01 and 34.66 , respectively. The effects in the two vital oils, independently and as a mixture, on 5 tumor cell lines, MCF-7, HS-1, HepG2, HeLa and A549, were investigated applying the MTT assay. The results indicated that the MCF-7 and HS-1 cell lines showed elevated sensitivity towards the myrrh and frankincense crucial oils compared using the remaining cell lines. In addition, the anticancer effects of myrrh were markedly increased compared with these of frankincense, nevertheless, no significant synergistic effects were identified. The flow cytometry outcomes indicated that apoptosis could be a major contributor for the biological efficacy of MCF7 cells. Introduction Commiphora myrrha has a yellow oleo-gum resin that exists in its stem and is made use of worldwide for the production of myrrh, especially in China and Egypt. The constituents of myrrh, incorporate volatile oil (2-8 ), resin (23-40 ), gum (40-60 ) and bitter principles (10-25 ). Prior research have shown thatmyrrh exhibits cytotoxic, analgesic, antiinflammatory, anticancer, antiparasitic and hypolipidemic activities (1-4). Frankincense is definitely an aromatic resin obtained from trees from the genus Boswellia and has been hypothesized to exhibit quite a few overall health supporting properties, such as the therapy of rheumatoid arthritis and antiinflammatory, antibacterial, antifungal and anticancer activities (5-8). Frankincense oil is prepared by the steam distillation of frankincense gum resin and is regularly employed in aromatherapy practices. As outlined by previous studies, the constituents of frankincense oil vary based on the climate, harvest conditions and geogra.
