Composition and Chemical Variability of Mentha suaveolens ssp. suaveolens and M. suaveolens ssp. insularis from Corsica

Abstract

A detailed analysis of two essential oils from individual plants of Mentha suaveolens ssp. suaveolens growing wild in Corsica was carried out by combination of GC(RI), GC/MS, and (13)C-NMR analyses. One oil sample is characterized by the pre-eminence of piperitenone oxide, and the second is dominated by piperitenone. In contrast, it was reported that the essential oil of M. suaveolens ssp. insularis, an endemic species to Corsica and Sardinia, contained pulegone and cis-cis-p-menthenolide as main components. A principal-component analysis (PCA) carried out on the composition of the essential oil of 59 individual plants of M. suaveolens sp. allowed the classification into three well-defined groups. All the oil samples from Mentha suaveolens ssp. insularis belonged to the same group, while the oils from M. suaveolens ssp. suaveolens were distributed in the two other groups. The composition of the essential oil isolated from aerial parts of M. suaveolens ssp. has been shown to be an additional tool to differentiate the botanically close subspecies suaveolens and insularis.

Antimicrobial Activity against Beneficial Microorganisms and Chemical Composition of Essential Oil of Mentha suaveolens ssp. insularis Grown in Sardinia

“…suaveolens have been widely studied by several authors (Ouzmil and others ; Benayad and others ), whereas M. suaveolens spp. insularis studies are limited to the plants collected in Corsica (Sutour and others , ).…”

Chemical composition of the essential oil and botanical study of the flowers ofMentha suaveolens

“…These include piperitone oxide (Hendriks et al, 1976;Holeman et al, 1985;Oumzil et al, 2002) and piperitenone oxide (Koliopoulos et al, 2010;Holeman et al, 1985;Oumzil et al, 2002;Sutour et al, 2010).…”

“…Some chemotypes of M. suaveolens showed high percentage of ketones such as pulegone (Oumzil et al, 2002;Sutour et al, 2008;Velasco-Negueruela et al, 1996), piperitenone (Sutour et al, 2010) and dihydrocarvone (Hendriks et al, 1976).…”

Application of Mentha suaveolens essential oil as an antimicrobial agent in fresh turkey sausages

“…The genus Mentha is one of the important elements of Lamiaceae family; it is represented by 19 species and 13 natural hybrids [12]. Among its species include Mentha suaveolens which located in North Africa, Europe, America, and Japan [13]. This plant has a wide range of benefits: Analgesic, stomachic, choleretic, tonic, carminative action, antispasmodic, hypotensive, sedative, insecticide, anti-inflammatory, hepatoprotective, antimicrobials, acetylcholinesterase, and monoamine oxidase inhibitors, it is applied also in the treatment of digestion problems, influenza, respiratory diseases, rheumatisms, skin diseases, irritation, nausea, anorexia, and bronchitis [14][15][16][17].…”

“…Its chemical composition depends on the region and season and consists mainly of terpenoids including monoterpenes, sesquiterpenes, and their oxygen derivatives [13,[17][18][19]. Formerly, essential oils of mint were used by the Egyptians, Romans, and Greeks populations as fragrances, food flavors, deodorizers, and pharmaceuticals products [20].…”
