The Complete Chloroplast Genome of Euphrasia regelii, Pseudogenization of ndh Genes and the Phylogenetic Relationships Within Orobanchaceae
Euphrasia (Orobanchaceae) is a genus which is widely distributed in temperate regions of the southern and northern hemisphere. The taxonomy of Euphrasia is still controversial due to the similarity of morphological characters and a lack of genomic resources. Here, we present the first complete chloroplast (cp) genome of this taxonomically challenging genus. The cp genome of E. regelii consists of 153,026 bp, including a large single-copy region (83,893 bp), a small single-copy region (15,801 bp) and two inverted repeats (26,666 bp). There are 105 unique genes, including 71 protein-coding genes, 30 tRNA and 4 rRNA genes. Al...

Minor acetylated metabolites from Euphrasia rostkoviana.
Abstract The phenylethanoids rostkovianoside, 6'-O-acetylcrassifolioside and the flavonoid rutin 3‴-acetate, were isolated from the methanolic extract of the aerial parts of Euphrasia rostkoviana Hayne. The structures of these previously undescribed compounds were elucidated by interpretation of spectroscopic data. The acetylation of rutin was also carried out and four ester derivatives were spectroscopically characterized. Finally, a chromatographic method was established to easily identify the acetylated position. PMID: 30450962 [PubMed - as supplied by publisher] (Source: Natural Product Research)

Endophytic Detection in Selected European Herbal Plants.
Authors: Goryluk-Salmonowicz A, Piórek M, Rekosz-Burlaga H, Studnicki M, Błaszczyk M Abstract A total of 181 cultivable endophytic bacterial isolates were collected from stems of 13 species of herbs inhabiting Europe (Poland): Chelidonium majus L., Elymus repens L., Erigeron annuus L., Euphrasia rostkoviana Hayne, Foeniculum vulgare L., Geranium pratense L., Humulus lupulus L., Matricaria chamomilla L., Mentha arvensis L., Papaver rhoeas L., Rosmarinus officinalis L., Solidago gigantea L. and Vinca minor L. The isolates were screened for their antifungal activity and fifty three were found to inhibit fungal...

Ecofriendly synthesis of silver and gold nanoparticles by Euphrasia officinalis leaf extract and its biomedical applications.
Authors: Singh H, Du J, Singh P, Yi TH Abstract Biogenic synthesis of silver (AgNPs) and gold nanoparticles (AuNPs) using aqueous extract of Euphrasia officinalis has been reported. Stable AgNPs and AuNPs were formed on adding aqueous solutions of silver nitrate and chloroauric acid with E. officinalis leaf extract, in 19 min and 2 min, respectively. The synthesis method used in present study was simple, reliable, rapid, cost effective and ecofriendly. The synthesized nanoparticles were characterized with field emission transmission electron microscopy (FE-TEM), elemental mapping, selected area diffra...

Research survey on iridoid and phenylethanoid glycosides among seven populations of Euphrasia rostkoviana Hayne from the Alps
Publication date: Available online 21 February 2017 Source:Phytochemistry Author(s): Angela Mari, Alexandru Ciocarlan, Nicola Aiello, Fabrizio Scartezzini, Cosimo Pizza, Michele D'Ambrosio The traditional use of extracts of Euphrasia rostkoviana to relieve ocular inflammation or infections is well documented and supported by clinical studies. Various classes of chemical compounds such as iridoids, phenylethanoids, flavonoids and hydroxycinnamic acids have been reported. The present work aims to assess the chemical diversity among seven populations of Euphrasia rostkoviana found in northern Italy. A meticulous separation o...

Plant hybrids in the wild: evidence from biological recording
Although plant hybrids are under‐recorded by botanists, the hybrids of Britain and Ireland are as well known as those of any comparable area. Of the 909 accepted hybrids, 301 have at least one alien parent and these include 152 taxa that have been introduced to the wild (usually from horticultural sources) as hybrids. The parental distributions of the spontaneous hybrids are described as either nested or overlapping; some of the most remarkable hybrids have parents with contrasting European distributions that overlap very narrowly. There are few annual or biennial hybrids and they tend to be sterile and closely associate...

Composition and Antimicrobial Activity of Euphrasia rostkoviana Hayne Essential Oil.
Authors: Novy P, Davidova H, Serrano-Rojero CS, Rondevaldova J, Pulkrabek J, Kokoska L Abstract Eyebright, Euphrasia rostkoviana Hayne (Scrophulariaceae), is a medicinal plant traditionally used in Europe for the treatment of various health disorders, especially as eyewash to treat eye ailments such as conjunctivitis and blepharitis that can be associated with bacterial infections. Some Euphrasia species have been previously reported to contain essential oil. However, the composition and bioactivity of E. rostkoviana oil are unknown. Therefore, in this study, we investigated the chemical composition and antimicrobi...
