Antimicrobial activity of limonene enantiomers and 1,8‐cineole alone and in combination
Abstract
Two common essential oil constituents, 1,8‐cineole and limonene, were assessed for antimicrobial activity, using the minimum inhibitory concentration (MIC) microtitre plate method against eight organisms. The limonene enantiomers, i.e. (+), (−) and the racemate, singularly and in combination (1:1) with 1,8‐cineole, were investigated to establish possible interactions. The MIC values were in the ranges 3–27 mg/ml for (+)‐limonene; 2–27 mg/ml for (−)‐limonene and 23 mg/ml for 1,8‐cineole, depending on the pathogen studied. The combinations, when investigated in a 1:1 ratio, mostly indicated reduced activity. Using various ratios of limonene and 1,8‐cineole, the specific interaction was further investigated against Staphylococcus aureus (Gram‐positive), Pseudomonas aeruginosa (Gram‐negative) and a yeast, Cryptococcus neoformans. A figurative representation of the results using isobologram construction indicated that, depending on the ratio and specific enantiomer, an additive, synergistic or antagonistic interaction may be observed.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
