Natural plant extracts (NPEs) may offer an effective alternative to minimize the consequences caused by antibiotic resistance in marine industry. In this study, anti-Vibrio parahaemolyticus activities of several antibiotics and NPEs alone combinations were evaluated. The results indicated that best combination was 1/4 minimum inhibitory concentration (MIC) oxytetracycline +1/4 MIC hawthorn extr...

The medicinal properties of hawthorn (Crataegus spp., a genus comprising approximately 300 species) have been utilized by many cultures for a variety of therapeutic purposes for many centuries. In the Western world cardiovascular disease (CVD) has become one of the single most significant causes of premature death. Echoing this situation, more recent research into the therapeutic benefits of ha...

UNLABELLED Crataegus succulenta Schrad. ex Link is widely spread in North America. A literature survey revealed no studies on the chemical composition and biological effects of this species. AIM The aim of the present study was to investigate the phenolic content, free radical scavenging and 15-lipoxygenase inhibitory effects of Crataegus succulenta leaf and flower extracts. MATERIAL AND ME...

Background: Many of neurodegenerative diseases (NDs) are associated with formation of the protein aggregates called amyloidal fibrils. Fibrillization of alpha-synuclein seems to be a key stage in the creation and progression of NDs and finding the compounds that inhibit the toxicity of alpha-synuclein aggregates seems to be one of the most attention subjects in the neurodegenerative studies. ...

Increasingly, attention is being paid to declaring the origin of agricultural and marine products after the advent of the bovine spongiform encephalopathy (BSE; commonly known as mad-cow disease). The display of the production centers on U. pinnatifida has been required in Japan since 2006. As an example of testing in another marine product, near-infrared spectra (NIR) and trace elemental analy...

During the course of screening plants for novel antifungal activity, we found that a high-molecular-mass fraction of an extract from leaves of Engelmannia pinnatifida exhibited potent and broad-spectrum antifungal activity. In this study a 30 kDa protein from E. pinnatifida leaves was purified to homogeneity by ammonium sulphate precipitation, gel filtration, Mono-Q and C18 reverse-phase column...

Phylogeographic relationships were constructed for 72 Old and New World Crataegus species using combinations of four chloroplast and up to five nuclear regions. Maximum parsimony, maximum likelihood, and Bayesian results yield consistent relationships among major lineages. The close associations of the East Asian and western North American species point toward ancient trans-Beringian migrations...
