The present study aimed to investigate the composition and prospective anticancer activities of essential oils obtained from two species, myrrh and frankincense, by hydrodistillation. Working with gas chromatography-mass spectrometry (GC-MS), 76 and 99 SGK drug components have been identified in the myrrh and frankincense crucial oils, respectively, with all 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 from the two necessary oils, independently and as a mixture, on 5 tumor cell lines, MCF-7, HS-1, HepG2, HeLa and A549, were investigated working with the MTT assay. The outcomes indicated that the MCF-7 and HS-1 cell lines showed increased 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 those of frankincense, even so, no substantial synergistic effects have been identified. The flow cytometry results indicated that apoptosis may well be a significant contributor to the biological efficacy of MCF7 cells. Introduction Commiphora myrrha features a yellow oleo-gum resin that exists in its stem and is utilized worldwide for the production of myrrh, specifically in China and Egypt. The constituents of myrrh, include things like volatile oil (2-8 ), resin (23-40 ), gum (40-60 ) and bitter principles (10-25 ). Earlier research have shown thatmyrrh exhibits cytotoxic, analgesic, antiinflammatory, anticancer, antiparasitic and hypolipidemic activities (1-4). Frankincense is definitely an aromatic resin obtained from trees on the genus Boswellia and has been hypothesized to exhibit several wellness supporting properties, including 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 often applied in aromatherapy practices. In line with earlier studies, the constituents of frankincense oil differ based on the climate, harvest situations and geogra.
