Phytochemical composition, hypnotic activity, and antinociceptive properties of cumin essential oil collected from various geographical regions.

The quantity and quality of the active components of plants are strongly influenced by environmental factors. In this regard, dried cumin seeds were collected from four different locations (SaadatShahr (P1) and Sarvestan (P2) from Fars Province and Kashmar (P3) and Sabzevar (P4) from Khorasan), and their essential oils were isolated by Clevenger apparatus and evaluated using GC and GC-MS. In addition, the hypnotic and antinociceptive activities of the cumin EO sample, which had the highest yield and quality, respectively, were assessed via the pentobarbital-induced loss of righting test and acetic acid-induced writhing test.

Genetic variation and structure of endemic and endangered wild celery ( Mozaff.) quantified using novel microsatellite markers developed by next-generation sequencing.

Mozaff. (Apiaceae) is a native plant that has been traditionally consumed in Iran's food and pharmaceutical industries. Overharvesting of the taxon, especially at the beginning of the growing season, due to its considerable medicinal and economic value, is believed to be the main reason for the extirpating of this plant.

Continuous decontamination of cumin seed by non-contact induction heating technology: Assessment of microbial load and quality changes.

Over the past few decades, the demand for high-quality food has increased steadily. Therefore, it is essential to develop innovative technologies that effectively reduce microbial load while minimizing any negative effect on the quality of spices. The objective of this study was to determine the efficacy of a self-designed non-contact induction heating system using contaminated cumin seeds.

Increasing the efficiency of cumin essential oil extraction using cold plasma pretreatments.

Background: Cumin (Cuminum cyminum L.) is one of the most important medicinal plants, and its essential oil (EO) varies between 2.5% to 5% depending on differences in climate.

Steps to achieve carvone-rich spearmint ( L.) essential oil: a case study on the use of different distillation methods.

Introduction: Spearmint essential oil is a valuable medical and food product. Spearmint essential oil is effective for the treatment of flatulence, indigestion, nausea, and colic along with Alzheimer, obesity, and fungal infections.

Methods: This study evaluated the quality and quantity of spearmint essential oil by examining some extraction strategies.

Improvement of phytochemical and quality characteristics of by drying methods.

This experiment was conducted to evaluate the effects of different drying methods on drying parameters and qualitative characteristics of in a completely randomized design with three replications. Treatments included shade drying as control, sun drying, cabinet drying (CD at 50 and 60°C), refractance window drying (RWD), infrared drying (IRD) at 200 and 300 W, and combination of RWD+ IRD at 200 and 300 W. According to the results, IRD, RWD, and RWD+ IRD effectively maintained valuable secondary metabolites compared to the conventional drying methods.

Optimization of ultrasonic Bath and cold plasma pre-treatments in the spearmint essential oil isolation process.

Spearmint essential oil (SEO), one of the economically valuable natural products, has special importance in the food, pharmaceutical, and perfumery industries due to its antifungal, antioxidant, and enzyme inhibitory properties. In this study, we optimized and evaluated the effect of three pre-treatments on the extraction of SEO for quantity and quality: ultrasonic bath (UB), water to material ratio-ultrasonic bath (W/M-UB), and cold plasma-ultrasonic bath (CP-UB). Three experiments were designed using the central composite design (CCD) of response surface methodology (RSM).

Decontamination technologies for medicinal and aromatic plants: A review.

Microbial quality assurance has always been an important subject in the production, trade, and consumption of medicinal and aromatic plants (MAPs). Most MAPs have therapeutic and nutritional properties due to the presence of active substances such as essential oils, flavonoids, alkaloids, etc. However, MAPs can become infected with microorganisms due to poor hygienic conditions during cultivation and postharvest processes.

A comparative study: Influence of various drying methods on essential oil components and biological properties of .

The genus is a member of the Lamiaceae family. These are important medicinal plants which grow all over the world and are known for their flavoring and therapeutic effects and is an endemic species of Iran. To acquire high-quality essential oil (EO), drying technique was implemented which is an essential part of this process.

Decontamination of peppermint distillate using spark plasma: microbiological and physicochemical evaluation.

Microbial contamination of herbal distillates is one of the crucial problems that the market is commonly facing. Spark plasma can be proposed as a potential emerging solution for the decontamination of liquids even with the sensitive aromatic compound like peppermint ( L.) distillate.

Precision Harvesting of Medicinal Plants: Elements and Ash Content of Hyssop (Hyssopus officinalis L.) as Affected by Harvest Height.

To investigate the effect of harvest height on the amassed elements and ash content of Hyssop (Hyssopus officinalis L.), an experiment was conducted in a randomized complete block design with three replications. Treatments included four harvest heights, i.

Effect of cold plasma on essential oil content and composition of lemon verbena.

Cold plasma is known as a novel nonthermal processing method for decontamination of medicinal and aromatic plants (MAPs); however, there are little research studies about its effects on active ingredients of these plants. The aim of this research was to investigate the influence of low-pressure cold plasma (LPCP) treatments (1, 3, and 5 min) on the essential oil (EO) content and composition of lemon verbena leaves. The EO content was determined using hydro-distillation, and the composition of the extracted EOs was quantified using gas chromatography and gas chromatography-mass spectrometry techniques.

Packaging methods and storage duration affect essential oil content and composition of lemon verbena ( Kunth.).

Changes in essential oils (EOs) content and composition of lemon verbena leave at different packaging methods (packaged with air, nitrogen, or under vacuum) and during storage period (0, 2, 4, 6 and 8 months) were determined. All the samples were hydrodistilled every 2 months during storage for EO content evaluation. EO composition was determined by gas chromatography and gas chromatography-mass spectrometry.
