Abstract
The bioactive compound, which showed a potent nitric oxide production stimulation effect, was isolated from Japanese red pine tea and identified as (+)-catechin. Compared with (−)-epigallocatechin 3-O-gallate and (−)-catechin, (+)-catechin exhibited greater NO production promotion and protection from H2O2-induced oxidative stress in vascular endothelial cells. The (+)-catechin content of Japanese red pine tea was found to be higher than that of buckwheat or green tea, both of which are known to contain (+)-catechin. This study indicated that (+)-catechin could be used as a potential functional ingredient for endothelium function protection and provides a basis for the use of red pine tea in endothelium dysfunction prevention in the future.

期刊介绍:
The NFS Journal publishes high-quality original research articles and methods papers presenting cutting-edge scientific advances as well as review articles on current topics in all areas of nutrition and food science. The journal particularly invites submission of articles that deal with subjects on the interface of nutrition and food research and thus connect both disciplines. The journal offers a new form of submission Registered Reports (see below). NFS Journal is a forum for research in the following areas: • Understanding the role of dietary factors (macronutrients and micronutrients, phytochemicals, bioactive lipids and peptides etc.) in disease prevention and maintenance of optimum health • Prevention of diet- and age-related pathologies by nutritional approaches • Advances in food technology and food formulation (e.g. novel strategies to reduce salt, sugar, or trans-fat contents etc.) • Nutrition and food genomics, transcriptomics, proteomics, and metabolomics • Identification and characterization of food components • Dietary sources and intake of nutrients and bioactive compounds • Food authentication and quality • Nanotechnology in nutritional and food sciences • (Bio-) Functional properties of foods • Development and validation of novel analytical and research methods • Age- and gender-differences in biological activities and the bioavailability of vitamins, minerals, and phytochemicals and other dietary factors • Food safety and toxicology • Food and nutrition security • Sustainability of food production
