Where is 'Yingyou' : the 'Tea Route' between Khitan and Southern Tang and its ports of departure Ghent University
During the period of "Five Dynasties and Ten KingdomsU+201D, the Khitan and the Kingdom of Wu and Southern Tang are in frequent contact for economic and geopolitical incentives. Being separated by central dynasties the Khitan-Southern Tang contact was never realistic nor successful via land route. Their diplomatic contact and business exchanges, however, were realized by maritime route via which plenty of tea were transported from the Southern ...
Total polyphenols content and antioxidant activity of different tea commercially produced in Nepal Ghent University
This study was conducted to assess and compare the total polyphenol content (TPC), antioxidant activity of different tea varieties commercially produced in Nepal. Nine different brands of tea samples, three from each CTC, orthodox and green tea were collected from different parts of Kathmandu valley. TPC was analyzed as per folin-ciocalteu method and antioxidant activity as per DPPH (2, 2-diphenyl-1-picrylhrdrazine) free radical scavenging ...
Total, caffeinated and decaffeinated coffee and tea intake and gastric cancer risk: results from the EPIC cohort study Ghent University
Prospective studies examining the association between coffee and tea consumption and gastric cancer risk have shown inconsistent results. We investigated the association between coffee (total, caffeinated and decaffeinated) and tea consumption and the risk of gastric cancer by anatomical site and histological type in the European Prospective Investigation into Cancer and Nutrition study. Coffee and tea consumption were assessed by dietary ...

Trace element content in tea brewed in traditional metallic and stainless steel teapots Vrije Universiteit Brussel
The migration of metals in tea brewed in metallic teapots was investigated. The teapots were obtained from North Africa stores in Brussels in 2005-2006 and in 2011. Chinese gunpowder green tea, the most commonly used tea in the Moroccan community, was used to prepare the tea. Tea brewed in metallic teapots was compared to tea brewed in a glass vessel in order to evaluate the contribution of the tea and the teapots to the metal concentrations in ...
Gut microbiota as a driver of the interindividual variability of cardiometabolic effects from tea polyphenols Ghent University
Tea polyphenols have been extensively studied for their preventive properties against cardiometabolic diseases. Nevertheless, the evidence of these effects from human intervention studies is not always consistent, mainly because of a large interindividual variability. The bioavailability of tea polyphenols is low, and metabolism of tea polyphenols highly depends on individual gut microbiota. The accompanying reciprocal relationship between tea ...
Ultrasound irradiation alters the spatial structure and improves the antioxidant activity of the yellow tea polysaccharide Ghent University
In this study, the impact of ultrasound irradiation on the structural characteristics and antioxidant properties of yellow tea polysaccharides with different molecular weights (Mw) were investigated. Native yellow tea polysaccharide containing YTPS-3N, YTPS-5N and YTPS-7N were prepared through precipitation with ethanol at various concentrations of 30%, 50%, and 70%, respectively, and irradiated with high intensity ultrasound (20 kHz) for 55 min ...
Acute hepatitis after treatment for hair loss with oral green tea extracts (Camellia sinensis) Ghent University
Nutritional additives based on green tea have been claiming various beneficial health effects. However, several case reports on hepatotoxicity after the intake of green, tea derivatives containing Camellia Sinensis have been published. We report a patient with an acute hepatitis after intake of an oral green tea derivative claiming protection against hair loss, showing a histological image compatible with drug induced hepatitis. Other important ...
