- Abstract
The present study aimed to examine the chemical composition and biological activity of essential oils extracted from Euphorbia macrorrhiza collected from Northwest China. The major constituents of the essential oils of aerial parts and roots of E. macrorrhiza are acorenone B (16.72% and 25.80%), (+)-cycloisosativene (14.94% and 12.40%), 3a-hydroxy-5b-androstane (10.62% and 5.52%), copaene (7.37% and 6.29%), l-calamenene (4.13% and 4.65%) and β-cedrene (8.40% and 7.98%), respectively. The minor components of them are thymene, γ-terpinene, thymecamphor, α-cedrene, zingiberene, trans-caryophyllene, β-chamigrene, curcumene, pentadecane, (-)-α-muurolene, cuparene, γ-cadinene, (Z)-3-heptadecene, 1,3,7,7-tetramethyl-2-oxabicyclo(4.4.0)dec-5-en-4-one, hexahydrofarnesyl acetone, γ-elixene and palmitinic acid. The antimicrobial and antitumor activitiy of the E. macrorrhiza essential oil against Staphyloccocus aureus, Escherichia coli, Canidia Albicans and Caco-2 cells were evaluated. Among all the tested microorganisms and Caco-2 cells, the essential oils showed the strongest inhibitory effect on Staphyloccocus aureus (MIC = 2.8 μg/mL) and Caco-2 cell (IC50 = 11.86 μg/mL), whereas no effect on Escherichia coli and Candida albicans. The data of this study suggested that the E. macrorrhiza essential oils have great potential as a natural medicine for microbial infections and cancers.
