Muturi EJ, Ramirez JL, Doll KM, Bowman MJ Journal of Medical Entomology, 2017 ABSTRACT: Essential oils are potential alternatives to synthetic insecticides because they have low mammalian toxicity, degrade rapidly in the environment, and possess complex mixtures of bioactive constituents with multi-modal activity against the target insect populations. Twenty-one essential oils were initially screened for their toxicity against… Read more »
Chemical composition of the essential oils isolated from peel of three citrus species and their mosquitocidal activity against Culex pipiens
Badawy MEI, Taktak NEM, El-Aswad AF Natural Product Research, 2017 ABSTRACT: Three essential oils (EOs) were isolated from the peel of citrus fruits Citrus reticulata L., Citrus reticulata chinase Blanco and Citrus sinensis (L.) Osbeck (Family: Rutaceae) and evaluated against Culex pipiens L.1758 (Family: Culicidae). Chemical composition indicated that the EOs were rich in essential phytochemicals including… Read more »
Perspectives on medicinal properties of natural phenolic monoterpenoids and their hybrids
Rajput JD, Bagul SD, Pete UD, Zade CM, Padhye SB, Bendre RS Molecular Diversity, 2017 ABSTRACT: Carvacrol, thymol and eugenol belong to a class of naturally presenting phenols with a ten-carbon unit, which are present in essential oils of many plants. These versatile molecules are incorporated as useful ingredients in many food products and find applications in… Read more »
Anti-oxidant activity and major chemical component analyses of twenty-six commercially available essential oils
Wang HF, Yih KH, Yang CH, Huang KF Journal of Food and Drug Analysis, 2017 ABSTRACT: This study analyzed 26 commercially available essential oils and their major chemical components to determine their antioxidant activity levels by measuring their total phenolic content (TPC), reducing power (RP), β-carotene bleaching (BCB) activity, trolox equivalent antioxidant capacity (TEAC), and 1,1-diphenyl-2-picrylhydrazyl free… Read more »
Carvacrol-rich oregano oil and thymol-rich thyme red oil inhibit biofilm formation and the virulence of uropathogenic Escherichia coli
Lee JH, Kim YG, Lee J Journal of Applied Microbiology, 2017 AIMS: Urinary tract infections are caused primarily by uropathogenic Escherichia coli (UPEC), and indwelling catheters are usually colonized by UPEC biofilms tolerant to common antibiotics. Hence, UPEC biofilms pose a substantial challenge, and there is an urgent need for effective control strategies. METHODS AND… Read more »
Antibacterial and Antifungal Activity of Essential Oils against Pathogens Responsible for Otitis Externa in Dogs and Cats
Ebani VV, Nardoni S, Bertelloni F, Najar B, Pistelli L, Mancianti F Medicines (Basel), 2017 ABSTRACT: Background: Essential oils (EOs) are recommended by some veterinarians to treat otitis externa in pets, but data about their efficacy in scientific literature are very scant. Methods:Nine commercial EOs, from roman chamomile (Anthemis nobilis L.), star anise (Illicium verum), lavender (Lavandula hybrida), litsea… Read more »
Essential Oils’ Chemical Characterization and Investigation of Some Biological Activities: A Critical Review
Dhifi W, Bellili S, Jazi S, Bahloul N, Mnif W Medicines (Basel), 2017 ABSTRACT: This review covers literature data summarizing, on one hand, the chemistry of essential oils and, on the other hand, their most important activities. Essential oils, which are complex mixtures of volatile compounds particularly abundant in aromatic plants, are mainly composed of terpenes biogenerated… Read more »
Computational tool for optimizing the essential oils utilization in inhibiting the bacterial growth
El-Attar NE, Awad WA Advances and Applications in Bioinformatics and Chemistry, 2017 ABSTRACT: Day after day, the importance of relying on nature in many fields such as food, medical, pharmaceutical industries, and others is increasing. Essential oils (EOs) are considered as one of the most significant natural products for use as antimicrobials, antioxidants, antitumorals, and anti-inflammatories. Optimizing… Read more »
Antibacterial activity and interactions of plant essential oil combinations against Gram-positive and Gram-negative bacteria
Semeniuc CA, Pop CR, Rotar AM Journal of Food and Drug Analysis, 2017 ABSTRACT: The aim of this study was to compare the antibacterial effects of several essential oils (EOs) alone and in combination against different Gram-positive and Gram-negative bacteria associated with food products. Parsley, lovage, basil, and thyme EOs, as well as their mixtures (1:1, v/v),… Read more »
Synergistic interaction of ten essential oils against Haemonchus contortus in vitro
Katiki LM, Barbieri AME, Araujo RC, Veríssimo CJ, Louvandini H, Ferreira JFS Veterinary Parasitology, 2017 ABSTRACT: Anthelmintic resistance in sheep gastrointestinal nematodes is a worldwide problem. Multi-drug resistant haemonchosis is the most serious impediment for small ruminant systems, and there are no new drug candidates currently under development. Molecules from natural sources have demonstrated anthelmintic… Read more »
