Molecules, Vol. 28, Pages 6395: Emerging Insights into the Applicability of Essential Oils in the Management of Acne Vulgaris
Maria Endres The occurrence of pustules, comedones, nodules, and cysts defines acne vulgaris, a prevalent chronic inflammatory dermatological condition. In the past few decades, essential oils extracted from varied natural sources have acquired recognition due to their potential medicinal applications in acne therapy. However, there is not yet sufficient medical data to fully characterize this interaction. Multiple factors contribute to the development of acne vulgaris, including excessive sebaceous production, inflammatory processes, hyperkeratinization, and infection with Cutibacterium acnes. Essential oils, includi...

Molecules, Vol. 28, Pages 6304: Analysis of the Antibacterial Properties of Compound Essential Oil and the Main Antibacterial Components of Unilateral Essential Oils
In this study, based on the analysis of the antibacterial properties of Chinese cinnamon bark oil and oregano oil, the proportion and concentration of the compound essential oil were optimized and designed, and the antibacterial activity of the compound essential oil was studied. The results showed that the antibacterial activity of Chinese cinnamon bark oil was higher than that of oregano oil. The compound essential oil prepared by a 1:1 ratio of Chinese cinnamon bark oil and oregano oil with a concentration of 156.25 ppm showed an excellent antibacterial activity against Escherichia coli and Staphylococcus aureus. The GC...

Alginate-based edible coating with oregano essential oil/ β-cyclodextrin inclusion complex for chicken breast preservation
Int J Biol Macromol. 2023 Aug 2:126126. doi: 10.1016/j.ijbiomac.2023.126126. Online ahead of print.ABSTRACTA sodium alginate (SA) edible coating containing oregano essential oil (OEO)/β-cyclodextrin (β-CD) inclusion complexes (SA/OEO-MP coating) was developed to extend the shelf life of fresh chicken breast during refrigeration storage. First, OEO was inserted into the hydrophobic interior of β-CD to form an inclusion complex (OEO-MP) that maintained its excellent antioxidant and antibacterial activities. The formed OEO-MP was characterized using Fourier transform ion cyclotron resonance (FTIR), X-ray diffraction (XRD),...

Sensors, Vol. 23, Pages 6800: Laser Sensing and Chemometric Analysis for Rapid Detection of Oregano Fraud
o Pollastrone World health is increasingly threatened by the growing number of spice-related food hazards. Further development of reliable methods for rapid, non-targeted identification of counterfeit ingredients within the supply chain is needed. ENEA has developed a portable, user-friendly photoacoustic laser system for food fraud detection, based on a quantum cascade laser and multivariate calibration. Following a study on the authenticity of saffron, the instrument was challenged with a more elusive adulterant, olive leaves in oregano. The results show that the reported method of laser sensing and chemometric analy...

The Impact of Origanum vulgare Supplementation on Human Asthenozoospermic Sperm Parameter Quality
ScientificWorldJournal. 2023 Jun 24;2023:8093795. doi: 10.1155/2023/8093795. eCollection 2023.ABSTRACTMale infertility is a complex multifactorial disease and a real health problem; 50% of infertile men have identifiable causes detectable by fundamental sperm analysis. Numerous research studies have shown the possibility of treating abnormal semen samples with some drugs before artificial insemination, yet evidence of the drug's effectiveness remains minimal. In our previous work, we tested the effectiveness of some essential oils, such as eucalyptus (Eucalyptus globulus Labill.), oregano (Origanum vulgare L.), and sage (S...

Molecules, Vol. 28, Pages 5302: A Comparative Evaluation of Antioxidant Activity of Extract and Essential Oil of Origanum onites L. In Vivo
a Sadauskiene In the present study, the effects of Origanum onites L. extract and essential oil of O. onites L. on the antioxidant status of the liver and brain of mice were investigated. Due to certain disadvantages of essential oils, such as poor solubility, high volatility and sensitivity to UV light and heat, formulation of liposomes with Oregano essentials (OE) was optimized and used in this study. The results demonstrated that the best composition of the lipid carriers and OE were conducted in terms of the polydispersity index (PDI), mean particle size and encapsulation efficiency (EE). For further study the LE4 ...

Authentication and identification of Lamiaceae family with cyclic voltammetry fingerprint-PCA-LDA and determination of the used phenolic contents for classification using chromatographic analyses
Talanta. 2023 Jul 4;265:124894. doi: 10.1016/j.talanta.2023.124894. Online ahead of print.ABSTRACTTodays, it is essential to evaluate and check the quality of herbal medicines in to protect the public health. As medicinal plants, the extracts of labiate herbs are used directly or indirectly to treat a variety of diseases. Increase in their consumption has led to the fraud in herbal medicines. Hence, modern accurate diagnostic methods must be introduced to differentiate and authenticate these samples. Electrochemical fingerprints have not been evaluated for their capacity to distinguish and classify various genera within a ...

Chemical composition and effect of essential oils of Thymus vulgaris and Origanum vulgare on adults and ovigerous masses of Pseudosuccinea columella 
Nat Prod Res. 2023 Jul 6:1-5. doi: 10.1080/14786419.2023.2233046. Online ahead of print.ABSTRACTFasciolosis is a worldwide distribution zoonosis that causes great damage in ruminant breeding and has the aquatic mollusc Pseudosuccinea columella as an intermediate host. Synthetic molluscicides are the most used for control; however, they are harmful to fauna and flora. Therefore, this study aimed to evaluate the effect of essential oils from Thymus vulgaris, Origanum vulgare, and terpene carvacrol, on adult molluscs and eggs of P. columella. Analysis of EO volatile components was carried out on a gas chromatograph equipment ...

Thermal desorption direct analysis in real ‐time high‐resolution mass spectrometry and machine learning allow the rapid authentication of ground black pepper and dried oregano: A proof‐of‐concept study
In this study, TD-DART-HRMS's utility for establishing spice authenticity was examined. To this aim, we directly analyzed authentic (typical) and adulterated (atypical) samples of ground black pepper and dried oregano in positive and negative ion modes. We analyzed a set of authentic ground black pepper samples (n = 14) originating from Brazil, Sri Lanka, Madagascar, Ecuador, Vietnam, Costa Rica, Indonesia, Cambodia, and adulterated samples (n = 25) consisting of mixtures of ground black pepper with this spice's nonfunctional by-products (pinheads or spent) or with different exogenous materials (olive kernel, green...
