“…The utilization of V. album in traditional medicine implies that it can also be used in modern medicine, especially in cancer and cardiovascular diseases (Gray & Flatt 1999). According to epidemiological studies, essential oil and phenolic compounds have inhibitive effects against the progress of bacterial infections (Ghuman et al 2016, Martinelli et al 2017. GC-MS chromatogram analysis of leaf extracts of V. album showed different peaks, which indicates the presence of 8 main phytochemical constituents ( Fig.…”

Many opportunistic pathogenic bacteria use the Quorum Sensing (QS) system to coordinate their virulence expressions. Thus, QS can likely be a new approach to control bacterial infections. The aim of this study was to evaluate the antimicrobial, anti-biofilm, and anti-quorum sensing activities of ethanol, chloroform, and dichloromethane: methanol extracts of leaf, stem, and fruits of the European mistletoe Viscum album L. on 2 Gram-positive and 7 Gram-negative pathogenic bacteria. The extracts at concentrations ranging from 50 to 250mg/ml were tested depending on the extracts of the plant parts and the test bacteria. The extract with 50mg/ml concentration, in which no antimicrobial activity was observed, was used for anti-quorum sensing and antibiofilm studies. The dichloromethane: methanol extracts were found to show the highest biological activities. QS activities of the plant extracts were also determined using the recently established Chromobacterium violaceum CV026 reporter strain and the signaling molecule N-(ß-ketocaproyl)-L-homoserine lactone (3-oxo-C6-HSL) agar well diffusion assay. Biofilm was quantified using the microtiter plate test and the crystal violet assay. Anti-microbial, anti-biofilm, and anti-quorum sensing activity of leaf and stem extracts showed higher efficiency than fruit extracts. It was concluded that the extracts of V. album had the potential to treat microbial infections by biofilm inhibition or inhibition of QS.

“…Essential oils and oleoresins are known to present a broad spectrum of action, including antioxidant activity and antibacterial activity. Even though the antimicrobial mechanism of action of essential oils and oleoresins is not fully understood, it is believed that the activity occurs due to their hydrophobicity (Martinelli et al, 2017;Rosa et al, 2018).…”

Due to the growth of the cosmetics industry, developments and improvements are needed for the productive sector and its products to meet consumer demand and the quality standards imposed by inspection bodies. As a result, an area has developed to meet these needs that is known as phytocosmetics. This area involves the inclusion of constituents with of plant origin in the cosmetic product formulation. The objective of this work was to compare the formulations of lip moisturizers incorporating oleoresins and essential oils of cinnamon (Cinnamomun verum), in addition to testing the microbiological safety and the Accelerated and Extended Stability of the formulated products. The tests revealed that the proposed formulations are microbiologically stable and safe, which is due to the antimicrobial activity of the oleoresin and cinnamon essential oil used in the formulations.

“…Essential oils have been applied for centuries in pharmaceuticals and alternative medicine. They are effective as antibacterial, antifungal, antiviral, anti-inflammatory, anti-oxidant, and as anti-cancer (Bakkali et al, 2008;Tarawneh et al, 2010;Benelli et al, 2017;Burt, 2004;Martinelli et al, 2017). Essential oils are secondary metabolites produced by aromatic plant families such as Apiaceae and Lamiaceae.…”

The aim of this study was to evaluate the antibacterial activity of Origanum ramonense essential oil extracted from the air-dried leaves against β-lactamase and extended-spectrum β-lactamase obtained from the patients with urinary tract infection. The essential oil was extracted by hydrodistillation and analyzed by GC–MS. In vitro antibacterial activity was studied using disc diffusion and microdilution methods. Twenty compounds were identified representing 97.8% of the total oil. The major components were carvacrol (84.6%), p-cymene (4.3%) and γ-terpinene (3.3%). The oil showed a broad spectrum of antibacterial activity against all tested isolates. Staphylococcus aureus, S. epidermidis, Klebsiella pneumoniae and Enterobacter aerogenes had the lowest minimum inhibitory concentration values (0.015 µg/mL) followed by Escherichia coli (0.14 µg/mL). The lowest susceptible strains to oil were Pseudomonas aeruginosa, Proteus mirabilis, E. coli 25922 and P. aeruginosa 10145. The bacteriostatic and bactericidal effects at concentrations as low as 0.015 µg/mL indicated the potent antibacterial activity of O. ramonense.
