Three types of Cocoa tea, green, oolong, and black, were prepared from fresh young leaves of Camellia ptilophylla. Their aroma characteristics were compared by a sensory evaluation with corresponding traditional tea samples made from C. sinensis. The aroma profile of Cocoa green tea was quite different from that of traditional green tea, but fermented Cocoa oolong tea and black tea showed aroma...

Basolateral transport of the prototypical type I organic cation tetraethylammonium (TEA) by the Malpighian tubules of Drosophila melanogaster was studied using measurements of basolateral membrane potential (V(bl)) and uptake of [(14)C]-labeled TEA. TEA uptake was metabolically dependent and saturable (maximal rate of mediated TEA uptake by all potential transport processes, reflecting the tota...

BACKGROUND Data relating to the association between tea consumption and blood pressure change are inconsistent. The aim of this analysis was to investigate the association between tea consumption and the change in blood pressure (BP) in Chinese adults over a 5-year period. METHODS Data from 1109 Chinese men (N= 472) and women (N= 637) who participated in the Jiangsu Nutrition Study (JIN) were...

BACKGROUND China has the world's largest tea plantation area in the world. To sustain high yields of the tea, multiple pesticides are used on tea crops to control pests. Organophosphorus (OP) pesticides are among the most widely used types of agricultural pesticides in China. As tea is a significant potential source of exposure to pesticide residues, the public concern has increased in relation...

Roasted stem tea has a characteristic flavour, which is obtained by roasting tea stems, by-product of green tea production. The difference between roasted stem and leaf tea derived from the same tea plants were investigated using GC–MS. Pyrazine compounds exhibited a roasted odour and high flavour dilution (FD) factors, as determined via aroma extract dilution analysis (AEDA). Roasted stem tea ...

BACKGROUND High caffeine intake is reportedly a risk factor for reduced bone mineral density (BMD) in women. Most studies, however, are from populations in which coffee drinking predominates and is the major caffeine source. Tea contains caffeine but also has other nutrients, such as flavonoids, that may influence bone mass in different ways. OBJECTIVE We examined the relation between tea dri...

We investigated whether polyphenolic extracts from black tea, green tea or red wine affect azoxymethane (AOM)-induced intestinal carcinogenesis. Male F344 rats were treated 10 times (1 week apart) with AOM (7.4 mg/kg, s.c.) and then allocated into groups receiving black tea, green tea or red wine extracts mixed in the diet at a dose of 50 mg/kg body weight for 16 weeks. In the rats treated with...

The importance of drug as a valuable export product in the global economy becomes more clear every day. Understanding the problems of exports and factors affecting it, can be an important step to keep Iran’s position in the world markets and further export development of this product.In this study, Iranian pharmaceutical exports’ supply and demand functions were calculated using co-integration ...

today export diversification has become one of the most important economic objectives of development strategies in the developing countries. for various reasons, such as preventing instability in export prices of primary products in global markets, reducing fluctuations in exchanges of them compared with industrial goods, producing dynamic benefits resulted from exporting various goods and incr...
