Olfactory learning in insects has been used extensively for studies on the neurobiology, genetics, and molecular biology of learning and memory. We show here that the ability of the cockroach Leucophaea maderae to acquire olfactory memories is regulated by the circadian system. We investigated the effect of training and testing at different circadian phases on performance in an odor-discriminat...

The antibacterial effect of thyme, peppermint, sage, black pepper and garlic hydrosols, widely used in food products as drinks and food additives, were tested for their inhibitory effects against Bacillus subtilis and Salmonella enteritidis. Single and combined hydrosols of previous common herbs were used to evaluate in vitro the antibacterial activity against these pathogenic bacteria. The obt...

Peppermint (Mentha piperita) is a plant native to Europe and has been widely used as a carminative and gastric stimulant worldwide. This plant also has been used in cosmetic formulations as a fragrance component and skin conditioning agent. This study investigated the effect of peppermint oil on hair growth in C57BL/6 mice. The animals were randomized into 4 groups based on different topical ap...

The monoterpene ketone l-menthone is specifically converted to l-menthol and l-menthyl acetate and to d-neomenthol and d-neomenthyl-beta-d-glucoside in mature peppermint (Mentha piperita L. cv. Black Mitcham) leaves. The selectivity of product formation results from compartmentation of the menthol dehydrogenase with the acetyl transferase and that of the neomenthol dehydrogenase with the glucos...

Biocompatible oil-in-water (o/w) micro-emulsions can be prospective drug delivery vehicles for their capability to solubilize lipophilic (oil soluble) drugs in the dispersed oil. Plant oils are considered suitable for such a purpose. In this study, we have attempted to examine the dispersion of corn, cottonseed, clove, orange and peppermint oils, as well as isopropyl myristate (IPM) in water co...

INTRODUCTION Nutrition can contribute to the development of gastroesophageal reflux disease (GERD). The relevant studies often provide contradictory results. AIM To determine GERD risk factors associated with dietary habits. MATERIAL AND METHODS A total of 513 subjects were included. The study group consisted of adults with a recent clinically confirmed diagnosis of GERD, and the control gr...

BACKGROUND AND OBJECTIVES The efficacy of Mentha piperita L, Zataria multiflora Boiss and Thymus vulgaris L essential oils (EOs) was evaluated for controlling the growth of Phytophthora drechsleri, the causative agent of damage to many crops that is consumed directly by humans. MATERIALS AND METHODS The EOs used in this study was purchased from Magnolia Co, Iran. The pour plate method in petr...

This study aims to evaluate the benefits of some herbs such as antioxidant, antibacterial, and anti-cancer activities Lemongrass (Cymbopogon citratus), peppermint (Mentha longifolia), wormwood (Artemisia absinthium) essential oils (EOs). The chemical composition was identified using GC-MS technique. total phenolic content antioxidant were monitored by radical scavenging assay (DPPH). Furthermor...
