In this study, the antibacterial, anti-efflux, anti-biofilm, anti-slime (exopolysaccharide) production and urease inhibitory efficacies of green synthesized gold nanoparticles (AuNPs) coated Anthemis atropatana extract against multidrug- resistant (MDR) Klebsiella pneumoniae strains were evaluated.
The antibacterial activity of the methanolic extract and its fractions of aerial parts of Aniheinis tinctoria (Asteraceae) was investigated against representative gram-positive Staphylococcus aureus (ATCC 25923) and Enterococcus faecalis (ATCC 29212) and gram-negative strains Escherichia coli (ATCC
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
Three linear sesquiterpene lactones, anthecotulide (1), hydroxyanthecotulide (2), and acetoxyanthecotulide (3), were isolated from the aerial parts of Anthemis auriculata. Five known flavonoids, taraxa-20(30)en-3beta-ol (4), and methyl vanillate (5) were also isolated. The structures and the
Anthemis wiedemanniana is known in folk medicine for the treatment of microbial infections, cancer and also urinary and pulmonary problems. In this study, the chemical composition of the essential oil from A. wiedemanniana was evaluated and its antibacterial activity was tested against 10 bacterial
In the present study the chemical composition of the essential oils from aerial parts and roots of Anthemis mixta L. and A. tomentosa L. was evaluated by GC and GC-MS, and their antibacterial activity tested against ten bacterial species. Hexadecanoic acid (15.2%) was recognized as the main
Nine sesquiterpene lactones, anthemin A (1), 1alpha-hydroxydeacetylirinol-4alpha,5beta-epoxide (2), anthemin C (3), tatridin A (4), 1-epi-tatridin B (5), anthemin B (6), 6-deacetyl-beta-cyclopyrethrosin (7), elegalactone A (8), and 1beta,4alpha,6alpha-trihydroxyeudesm-11-en-8alpha-12-olide (9), were
Enoyl-ACP reductase (FabI) is a key enzyme of the type II fatty acid biosynthesis (FAS-II) pathway and a validated antimicrobial target. In the current study, three linear sesquiterpene lactones obtained from Anthemis auriculata, namely anthecotulide (1), 4-hydroxyanthecotulide (2) and
The essential oil obtained from the flowering parts of Anthemis altissima L. var. altissima was analysed by gas chromatography and gas chromatography mass spectroscopy. In this study, 34 compounds representing 98.76% of the essential oil were identified. The main components were α-terpineol
The sesquiterpene lactone anthecotulide (1) was extracted from Anthemis cotula in 0.7% w/w yield. A pure standard was prepared by preparative TLC and used for quantitative determination of 1 with a TLC scanner. The constitution of 1 was corroborated and the double-bond configuration determined. It
In the present study, the chemical composition of the essential oil from the aerial parts of Anthemis secundiramea Biv. subsp. secundiramea L. collected in Sicily was evaluated by GC and gas chromatography-mass spectrometry. The main components of A. secundiramea were (Z)-lyratyl acetate (14.6%),
Introduction
Traditionally,
Anthemis genus has been used for the treatment of gastrointestinal disorders, haemorrhoid and stomach ache in Europe. There are several
in-vitro and
in-vivo studies that showed the pharmacological properties of
From the ethanol extract of the blossoms of Anthemis nobilis L. (syn. Chamaemelum nobile L.), six new hydroperoxides (1-6) were isolated, besides the known 1 beta-hydroperoxyisonobilin (7). The structures were elucidated by spectroscopic methods and in some cases ascertained by synthesis. Compounds
This study aim to synthesize silver nanoparticles (AgNPs) using Anthemis atropatana extract and to evaluate their chemical characteristics and antimicrobial and cytotoxic effects. The biosynthesis of AgNPs is verified using UV-visible spectrum which showing maximum absorption in 430 nm wavelength.
To determine the exact structure of previously tentatively identified minor essential-oil constituents of a Chamomile species (Antemis segetalis Ten. (Asteraceae)), we have synthesized a small combinatorial library of 54 regioisomeric allylmethoxyphenyl pentanoates and 2-pentenoates (49 completely
