Essential oils of Mentha pulegium and Mentha rotundifolia from Uruguay

Abstract

Essential oils obtained by hydrodistillation from leaves of Mentha pulegium L. and Mentha rotundifolia (L.) Huds. from Uruguay were analysed by GC-FID and GC-MS. Oxygen-containing monoterpenes were the main group of constituents in both oils. Pulegone, isomenthone and menthone were the major components in the oil of M. pulegium, whereas piperitenone oxide and (Z)-sabinene hydrate were the major ones in M. rotundifolia. Enantiomerically pure (-)-menthone, (+)-isomenthone, (+)-isomenthol, (-)-menthol and (+)-pulegone were detected by multidimensional gas chromatography in the case of M. pulegium oil.<br>Óleos essenciais obtidos por hidrodestilação das folhas de Mentha pulegium L. e Mentha rotundifolia (L.)

O grupo de monoterpenes oxigenados foi o mais importante em ambos os óleos, sendo que a pulegona, isomenthona e menthona foram os constituintes maioritarios no óleo de Mentha pulegium, no entanto, o ôxido de piperitenona e (Z)-hidrato de sabineno foram os maioritarios na Mentha rotundifolia. (-)-mentone, (+)-isomentone, (+)-isomenthol, (-)-menthol e (+)-pulegone enantioméricamente puras foram detectadas por cromatografía gasosa multidimensional no caso do óleo de Mentha pulegium

Phytochemical study and insecticidal activity of Mentha pulegium L. oils from Morocco against Sitophilus Oryzae

“…Similarly, pennyroyal oils from different Algerian sites are characterized by the predominance of pulegone with different proportions 43.3 to 87.3% 36 . Similar results were obtained from Uruguay 7 and Tunisia 12 , the main compounds are respectively pulegone (73.4% and 61.11%) and isomenthone (12.9% and 17.02%). In Egypt, the pennyroyal oil is rich in pulegone (43.5%) and piperitone (12.2%) 9 .…”

“…The chemical composition of the pennyroyal oil has been described by several studies 4,[6][7][8][9][10][11][12][13][14] . Pennyroyal oils are characterized by the preponderance of pulegone (70-90%) along with other monoterpenic ketones such as menthone, isomenthone and piperitenone 15 .…”

Eficácia do mentol como anestésico para juvenis de tilápia-do-nilo (Oreochromis niloticus)

“…O mentol é um óleo essencial com propriedades anestésicas, antiespasmódicas, anti-inflamatórias, antiúlceras e antivirais, sendo de grande importância econômica na indústria farmacêutica (Lorenzo et al, 2002) e também na alimentícia e de cosméticos. O mentol é amplamente utilizado na anestesia de invertebrados marinhos (Ruppert e Barnes, 1996), mas não é um anestésico regulamentado para uso em peixes, e nem se conhece seu período de carência no tecido dos animais.…”

Preliminary study of the antimicrobial activity of Mentha x villosa Hudson essential oil, rotundifolone and its analogues

“…Several species of mentha have been investigated because of the essential oil produced by their leaves (Hiruma, 1993;Monte et al, 2001;Gobert et al, 2002;Lorenzo et al, 2002;Marchese et al, 2005;Sartoratto et al, 2004;Bertini et al, 2005;Bieski, 2005). The genus Mentha, family Labiatae, of the subfamily Nepetoidae and of the tribe Mentheae, is composed by approximately, 25 species.…”
