Hydrodistilled oils of the fresh aerial parts of Mentha suaveolens Ehrh. cultivated in Egypt were prepared from samples collected along the four seasons. The percentage yields of these essential oils were 0.50%, 0.52%, 0.60%, and 0.47% of the dry weight for winter, spring, summer, and autumn samples. GC/MS analyses of all samples revealed a qualitative and quantitative variability in the oil co...

BACKGROUND This study is aimed at determining the efficacy of Mentha spicata (M. spicata) and Mentha × piperita (M. × piperita) in preventing chemotherapy-induced nausea and vomiting (CINV). METHODS This was a randomised, double-blind clinical trial study. Prior to the study, patients were randomly assigned into four groups to receive M. spicata or M. × piperita. Statistical analysis included...

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.

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...
