Our TLC study of the volatile oil isolated from Mentha longifolia showed a major UV active spot with higher Rf value than menthol. Based on the fact that the components of the oil from same plant differ quantitatively due to environmental conditions, the major spot was isolated using different chromatographic techniques and identified by spectroscopic means as pulegone. The presence of pulegone...

background & aim: peppermint (mentha piperita l.) oil is one of the most popular and widely used as an essential oil. the aim of this study was to identify of the chemical components of peppermint cultivated in isfahan climatic conditions. experimental: the aerial parts of the plants were collected from a filed in meymeh, isfahan province in 2012. the essential oil was extracted by a cleven...

there is a growing interest in food industry to replace the synthetic chemicals by the natural products with bioactive properties from plant origin. the aim of this study was to determine the chemical composition of mentha pulegium essential oil and to characterize the antimicrobial activities of the essential oil. the essential oil of mentha pulegium was analyzed by gc-ms. the evaluation of th...

In this paper we present the results of studying the effects of the essential oil of Calamintha glandulosa Silic (EOCG) on the isolated rat ileum. C. glandulosa Silic has been used in folk medicine as an antispasmodic. EOCG (0.003-1 mg/ml) inhibited spontaneous contraction of the ileum (EC50 of 210.48 +/- 9.12 microg/ml). The calcium channel blocking activity was confirmed by inhibition of K(+)...

The aim of this research was to determine the chemical composition and nematicidal activity of essential oil of Agastache rugosa flowering aerial parts against the root knot nematode, Meloidogyne incognita, and to isolate and identify any nematicidal constituents from the essential oil. The essential oil of A. rugosa aerial parts was obtained by hydrodistillation and analyzed by GC-FID and GC-M...

Background & Aim:Mentha longifolia (L.) Huds is an aromatic perennial herb that belongs to the   family Lamiaceae. The aim of this study was to identify chemical composition of aerial parts   (including leaf, stem and flowers) of M. longifolia collected from   (Kamu mountain) Isfahan province. Experimental: The essential oils were extrac...

(R)-(+)-Pulegone, a monoterpene ketone, is a major component of pennyroyal oil. Ingestion of high doses of pennyroyal oil has caused severe toxicity and occasionally death. Studies have shown that metabolites of pulegone were responsible for the toxicity. Previous metabolism studies have used high, near lethal doses and isolation and analysis techniques that may cause degradation of some metabo...
