In-vitro antimicrobial activity of four diallyl sulphides occurring naturally in garlic and Chinese leek oils
Abstract
The in-vitro antimicrobial activity of garlic oil, Chinese leek oil and four diallyl sulphides occurring naturally in these oils against Staphylococcus aureus, methicillin-resistant S. aureus (MRSA), three Candida spp. and three Aspergillus spp. (total of 276 clinical isolates) was studied. The magnitude of activity of the four diallyl sulphides followed the order diallyl tetrasulphide > diallyl trisulphide > diallyl disulphide > diallyl monosulphide. These results suggest that disulphide bonds are an important factor in determining the antimicrobial capabilities of these sulphides. The concentration of four diallyl sulphides in garlic and Chinese leek oils was in the range 41.7-52.7% of total sulphides. Garlic oil, with a higher concentration of four diallyl sulphides, showed greater antimicrobial activity than Chinese leek oil. Diallyl disulphide, diallyl trisulphide, diallyl tetrasulphide and the oils rich in these sulphides may have a role in the prevention or treatment of infections.

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.
