Two new monocyclic monoterpenoid glycosides, rel-(1R,2S,3R,4R) p-menthane-1,2,3-triol 3-O-β-D-glucopyranoside (1) and rel- (1S,2R,3S) terpinolene-1,2,3-triol 3-O-β-D-glucopyranoside (2) were isolated from aqueous acetone extract of the aerial parts of Mentha haplocalyx Briq.. Their structures were elucidated through spectral analysis using MS and NMR spectrometers.

Introduction and objective: Opportunistic fungal infections have been a common cause of morbidity and mortality in the immunosupresed individuals such as AIDS and organ recipients. Treatment of these infections is a great challenge, thus antifungal therapy is playing a greater role in their health care. Traditional plants are a valuable source of novel antifungals. The aim of this study was to ...

Near-infrared spectroscopy combined with partial least squares regression (PLSR) and support vector machine (SVM) was applied for the rapid determination of chemical component of volatile oil content in Mentha haplocalyx. The effects of data pre-processing methods on the accuracy of the PLSR calibration models were investigated. The performance of the final model was evaluated according to the ...

Introduction: Mentha piperita L, a lesser-known and partly proved drug in homoeopathy, is used extensively as herbal medicine.

Changes in essential oil composition of peppermint (Mentha x piperita L.) affected by yeast extract and salicylic acid foliar application

The aim of this research was to determine chemical composition and insecticidal activity of the essential oil of Illicium pachyphyllum fruits against two grain storage insects, Sitophilus zeamais and Tribolium castaneum, and to isolate any insecticidal constituents from the essential oil. The essential oil of I. pachyphyllum fruits was obtained by hydrodistillation and analyzed by GC-MS. A tota...

BACKGROUND Recently, there has been an increased interest in the effects of essential oils on athletic performances and other physiological effects. This study aimed to assess the effects of Citrus sinensis flower and Mentha spicata leaves essential oils inhalation in two different groups of athlete male students on their exercise performance and lung function. METHODS Twenty physical educati...
