We examined the composition and antimicrobial activity of two essential oils from Chloranthus japonicus Sieb. and Chloranthus multistachys Pei. GC-FID and GC-MS analyses identifi ed 48 and 39 compounds, which represented 95.56% and 94.58%, respectively, of all components in these oils. Of these, 28 ...
We examined the composition and antimicrobial activity of two essential oils from Chloranthus japonicus Sieb. and Chloranthus multistachys Pei. GC-FID and GC-MS analyses identifi ed 48 and 39 compounds, which represented 95.56% and 94.58%, respectively, of all components in these oils. Of these, 28 compounds were common to both, with a relatively high amount of oxygenated monoterpenes (50.95% and 39.97%). Antimicrobial properties were evaluated in vitro via disc diffusion and microbroth dilution assays. Activities were strong against most tested microorganisms, with inhibition zones ranging from 8.1 to 22.2 mm. For both species, minimum values for inhibitory and bactericidal concentrations were 0.39 to 12.50 mg/mL and 0.78 to 50.00 mg/mL, respectively. These results suggest that these essential oils are potent natural sources of antimicrobial agents for the medicinal and pharmaceutical industries
