Figure 1From: Composition and cytotoxic activity of essential oils from Xylopia aethiopica (Dunal) A. Rich, Xylopia parviflora (A. Rich) Benth.) and Monodora myristica (Gaertn) growing in Chad and Cameroon Dose-dependent cytotoxic effect of the essential oils of X. parviflora from Chad (A) and Cameroon (B), X. aethiopica from Chad (C) and Cameroon (D) and M. myristica from Chad (E) and Cameroon (F). Human breast cancer (MCF-7) and normal (ARPE-19) cell lines were incubated 72 h with increasing doses of essential oils from 0.1 to 2 μL/mL. After treatment, cytotoxicity was measured by MTT assay as described in Material and Methods. Values are means ± standard deviations of three independent experiments.Back to article page
