Antioxidant effect of aromatic volatiles emitted by Lavandula dentata, Mentha spicata, and M. piperita on mouse subjected to low oxygen condition.
This study aims to investigate the antioxidant effect of aromatic volatiles of three common aromatic plants, Lavandula dentata, Mentha spicata, and M. piperita. In this study, kunming mice subjected to low oxygen condition were treated with the volatiles emitted from these aromatic plants through inhalation administration. Then the blood cell counts, and the activities and gene expressions of antioxidant enzymes in different tissues were tested. The results showed that low oxygen increased the counts of red blood cells, white blood cells, and blood platelets of mice, and aromatic volatiles decreased their counts. Exposure ...

Evaluation of eco-friendly compounds in the manufacturing of antibacterial papers.
Abstract
The papers have a porous structure which can be a suitable medium for the growth of bacteria. Therefore, in the sanitary papers, creation of a suitable antibacterial property is necessary. In this way, the plant extracts were prepared using solid-liquid extraction method from the Rosmarinus officinalis, Olea europaea, Mentha spicata and Punica granatum. Relatively, the total phenol and flavonoid contents were determined according to colorimetric method. Their antioxidant activity was evaluated using DPPH method. The extracts were sprayed on the surface of the handsheets, and then their antibacteri...

Herbal Use and Medical Pluralism Among Latinos in Southern California
AbstractComplementary and alternative medicine (CAM) is often used alongside conventional medical care, yet few patients disclose CAM use to medical doctors. Our objectives were to (1) assess Latino herbal use, (2) explore the most commonly used herbs for common ailments, and (3) examine patients ’ disclosure of herb use to their physicians. Self-administered questionnaires were collected from 318 Latino patients seeking treatment at community health centers. Descriptive statistical analysis was conducted to determine the frequency of stated objectives among the participants. Fisher’s ex act test was used to compare di...

Protective effects of Mentha spicata against nicotine-induced toxicity in liver and erythrocytes of Wistar rats
Applied Physiology, Nutrition, and Metabolism, e-First Articles. The aim of this study was to investigate the protective effect of Mentha spicata supplementation against nicotine-induced oxidative damage in the liver and erythrocytes of Wistar rats. Bioactive substances were determined by liquid chromatography – electrospray ionization – tandem mass spectrometry analysis. Animals were divided into 4 groups of 6 rats each: a normal control group, a nicotine-treated group (1 mg/kg), a group receiving M. spicata extract (100 mg/kg), and a group receiving both M. spicata extract (100 mg/kg) and nicotine ( 1 mg/kg). Many ph...

Structural re-arrangement of depolymerized sodium alginate enriches peltate glandular trichomes and essential oil production of spearmint.
Abstract
Over the past decade, radiation-degraded polysaccharides have been used as regulators of growth and development of plants in several crop plants. In quest of the possible reasons of previously established growth-promotion activity of irradiated sodium alginate (ISA), structural parameters of irradiated and un-irradiated sodium alginate were analysed using Ultraviolet-visible spectroscopy (UV-vis) and Fourier Transform Infrared spectroscopic (FT-IR) studies to develop an understanding of structure-property relationship. Using foliar application, response to graded concentrations of ISA was tested i...

Effect of Mentha spicata essential oil on chemical, microbial, and sensory properties of minced camel meat during refrigerated storage
Abstract
The aim of the present study was incorporation of Mentha spicata essential oil (MSO) at three different concentrations (0.5, 1, and 1.5% vol/wt) into raw minced camel meat to extend shelf life and evaluate its antibacterial activity against Listeria monocytogenes for 12 days at refrigerated temperature. Final microbial population (total mesophilic and psychrotrophic bacteria, Pseudomonas spp., Enterobacteriaceae, and L. monocytogenes) decreased approximately 1–4 log CFU/g in treated samples compared to control. The initial total volatile base nitrogen was 8.86 ± 0.33 mg/100 g and after 12 days reached to 39...

Consumers' acceptance of medicinal herbs: An application of the technology acceptance model (TAM)
Conclusions Findings provide a useful evaluation of the acceptance of medicinal herbs and may serve as a benchmark for future research and evaluation concerning the use of medicinal herbs over time. For plant producers, more effective and targeted crop development should be encouraged, whereas for retailers better marketing and delivery strategies should be sought.

Structural determinants of a conserved enantiomer-selective carvone binding pocket in the human odorant receptor OR1A1.
Abstract
Chirality is a common phenomenon within odorants. Most pairs of enantiomers show only moderate differences in odor quality. One example for enantiomers that are easily discriminated by their odor quality is the carvones: humans significantly distinguish between the spearmint-like (R)-(-)-carvone and caraway-like (S)-(+)-carvone enantiomers. Moreover, for the (R)-(-)-carvone, an anosmia is observed in about 8% of the population, suggesting enantioselective odorant receptors (ORs). With only about 15% de-orphaned human ORs, the lack of OR crystal structures, and few comprehensive studies combining i...

Disinfection efficiencies of sage and spearmint essential oils against planktonic and biofilm Staphylococcus aureus cells in comparison with sodium hypochlorite.
This study explored the potential antibacterial actions of sage and spearmint essential oils (EOs) against both its planktonic and biofilm cells, in comparison with sodium hypochlorite (NaOCl), a commonly applied chemical sanitizer. Initially, the minimum inhibitory and bactericidal concentrations (MICs, MBCs) of each plant mixture were determined against planktonic cultures, following growth at 30°C for 24h. Stationary phase planktonic bacteria were then individually exposed for 6min to either each EO (applied at 1-2×MBC; 2.5-5%), or NaOCl (250-450ppm). These were also left to form biofilms on 96-well polystyrene microp...

Deodorization of garlic odor by spearmint, peppermint, and chocolate mint leaves and rosmarinic acid
This study determined the deodorizing effect of 3 types of fresh mint leaves (peppermint, spearmint, and chocolate mint) and pure rosmarinic acid on garlic volatiles. Garlic volatiles were measured in the headspace of a sealed bottle containing pre-weighed garlic cloves blended with mint leaves, rosmarinic acid, or a mint leaves-rosmarinic acid mixture, using selected ion flow tube-mass spectrometry (SIFT-MS). All 3 mint leaf cultivars significantly reduced the headspace concentrations of sulfur volatiles in crushed garlic. Although chocolate mint leaves had the highest rosmarinic acid content, peppermint and spearmint lea...
