TL;DR: In this article, the antimicrobial and antioxidant activities of the essential oil and methanol extract from Mentha longifolia ssp. l. is evaluated, and the extract showed strong antimicrobial activity against all 30 microorganisms tested whereas the essential oils almost remained inactive.
551 citations
TL;DR: The in vitro antioxidant activity of L. alba essential oil, obtained by hydrodistillation was evaluated by determination of hexanal, the main carbonyl compound released by linoleic acid subjected to peroxidation, and by quantification of this acid as its methyl ester under the same conditions.
333 citations
TL;DR: Gram-positive bacteria were found to be more sensitive to the essential oils than Gram-negative bacteria, and Staphylococcus aureus was the most sensitive strain while Pseudomonas aeruginosa was themost resistant.
299 citations
TL;DR: This investigation showed that the oil of Mentha pulegium L. piperitone/piperitenone oil has a potent antimicrobial activity and the Iranian Mentha Pulegia L. oil belongs to p Piperitone/ piperitENone type.

TL;DR: Pulegone‐rich essential oil inhibited efficiently all the micro‐organisms tested with MICs ranging between 0.69 and 2.77 ppm, and was the most effective against the tested microorganisms, followed by PEO and PO.
Abstract: The essential oils (EO) of Mentha suaveolens, a wild Labiatae, which grows in several regions in Morocco, were characterized and their antimicrobial activity assessed. The main aromatic constituents of this plant, as characterized by IR, NMR and MS studies, were pulegone, piperitenone oxide (PEO) and piperitone oxide (PO) occurring in different amounts depending on the subspecies. These constituents as well as a series of other aromatic products such as carvone, limonene and menthone, were tested for their antimicrobial activity against 19 bacteria including Gram-positive and Gram-negative and against three fungi, using solid phase and microtitration assays. Pulegone-rich essential oil inhibited efficiently all the micro-organisms tested with MICs ranging between 0.69 and 2.77 ppm. Among the components from Mentha suaveolens EO, pulegone was the most effective against the tested microorganisms, followed by PEO and PO. The structure-activity relationship is discussed on the basis of the activity of the other aromatic derivatives tested such as carvone, limonene, menthone and the profile of the essential oils of Mentha suaveolens was compared with other Mentha species.
