The objective of this study was to investigate the chemical composition and in vitro antifungal activity Mentha × Piperita L. (peppermint) essential oil (EO) against some plant pathogenic fungi (Alternaria alternata, Penicillium expansum, Rhizoctonia solani, Rhizopus stolonifer). Antifungal EO selected conducted using agar diffusion method by adding peppermint concentrations (0, 250, 500, 750, ...

Anthelmintic resistance is a worldwide concern in small ruminant industry and new plant-derived compounds are being studied for their potential use against gastrointestinal nematodes. Mentha piperita, Cymbopogon martinii and Cymbopogon schoenanthus essential oils were evaluated against developmental stages of trichostrongylids from sheep naturally infected (95% Haemonchus contortus and 5% Trich...

a valuable composition of mentha piperita l. essential oil is menthol that is widely used fordifferent industries. the plants were treated with different concentrations of methyl jasmonate (meja) and after 24 h were evaluated for total soluble proteins, chlorophylls (a, b, and total), malondialdehyde, carbohydrates and antioxidant enzymes (superoxide dismutase and guaiacol peroxidase). variance...

The precursor of all monoterpenes is the C10 acyclic intermediate geranyl diphosphate (GPP), which is formed from the C5 compounds isopentenyl diphosphate and dimethylallyl diphosphate by GPP synthase (GPPS). We have discovered that Antirrhinum majus (snapdragon) and Clarkia breweri, two species whose floral scent is rich in monoterpenes, both possess a heterodimeric GPPS like that previously r...
