The experiments were carried out to study the kinetics of mentha oil extraction from mentha leaves (Mentha arvensis L.) and the quality analysis was carried out for the oil extracted. The oil was extracted from mentha leaves at three different moisture contents of 74.30 per cent (fresh leaves), 42.30 per cent (shade dried) and 19.35 per cent (sun dried) using hydro distillation method. Various ...

The chemical composition of mentha essential oil and mentha extracts obtained at different pressures/temperatures by supercritical fluid extraction (SFE) were studied by GC–MS. The menthol content was also determined spectrophotometrically. The predominant compounds in the essential oil and in the CO2 extract obtained at 100 bar were L-menthon and menthole but at higher pressures (from 150 to 4...

Aspergillus species are pollutants found in both food and air. The increase the metabolic activity of leads to spoilage foodstuffs large economic losses. In addition, some have ability produce aflatoxins ochratoxins, secondary metabolites called, namely, mycotoxins. Especially mycotoxins very important terms safety human health. Since protection animal health prevention losses is a issue, our s...

Cholinesterase inhibitors are the class of compounds which inhibit cholinesterase enzyme. These are used as drugs for symptomatic treatment of Alzheimer’s disease (AD). The present study, evaluate anti-cholinesterase property of an aqueous extract of Mentha longifolia leaves, which is an aromatic plant traditionally used for several medicinal properties. Ellman’s method was used to determine th...

many powdery mildew fungi occur as anamorphic state on different host plants in guilan province, iran. the species have usually been identified as oidium spp. in order to identify teleomorphic species using anamorphic characteristics and host range, several infected plant specimens were collected from around guilan province during 2004-2011. based upon  the  results of the study 25 species were...

The adsorption of the Alizarin Red S (ARS) and Patent Blue VF (PBVF) from aqueous solution onto agricultural waste mentha has been investigated. The effects of initial dye concentration, contact time, pH, temperature and ionic strength were studied in a batch system. ARS and PBVF adsorption onto mentha increased to minor extent with decreasing pH. Adsorption capacities of dyes increased with co...

BACKGROUND Mentha piperita L. (Labiatae) is an herbaceous plant, used in folk medicine for the treatment of several medical disorders. METHODS AND RESULTS In the present study, the aqueous extract of Mentha piperita leaf, at the i.p doses 200 and 400 mg/kg, showed significant analgesic effects against both acetic acid-induced writhing and hot plate-induced thermal stimulation in mice, with pr...

A diastereomeric mixture of antlers (compounds (SP)-9 and (RP)-9) cannot be separated while attached to the deer. In winter, however, deer will lose single antler-diastereomers, they can resolved collected provide a robust starting material for (chiral) tools, like spears, axes or homogeneous catalysts. Note useful enantiomerically pure (−)-menthol-containing food (Mentha arvensis) available Mo...
