A new genus and two new species of mites in the family Eriophyidae, Theaphyes rapaneae gen. n. and sp. n. which is found on the type host Rapanea neriifolia (Sieb. et Zucc.) Mez (Myrsinaceae) and Paracaphyllisa theacea sp. n., are described and illustrated. They are vagrants on the tea plant Camellia sinensis (L.) Kuntze and no apparent symptoms were detected. A key to the eriophyoid mites incl...

Green tea is manufactured from the leaves of the plant Camellia sinensis Theaceae and has been regarded to possess anti-cancer, anti-obesity, anti-atherosclerotic, anti-diabetic, anti-bacterial, and anti-viral effects. Many of the beneficial effects of green tea are related to the activities of (-)-epigallocatechin gallate (EGCG), a major component of green tea catechins. For about 20 years, we...

The incorporation of [G -3H]-dihydrokaempferol into catechins of young tea shoots Camellia sinensis L.) was compared with that of l [ U 14C]-phenylalanine and [U -14C]-shikimic acid. The percent incorporation of all three precursors into (— )epicatechin was about equal, whereas the incorporation of shikimic acid into the galloylated catechins was somewhat higher than that of phenylalanine and d...

Tea (Camellia sinensis) is a widely consumed beverage and recognised for its potential enhancing effect on human health due to its rich polyphenol content. While a number of studies have investigated the quantity and type of polyphenols present in different tea samples, no study has reported the potential effect of digestive enzymes on the availability of tea polyphenols for human absorption or...

For more than 1000 years green tea has been used in China and Japan as a medical herb and a healthful beverage. The traditional Chinese medicine has recommended this plant for headaches, body aches and pains, digestion, depression, detoxification, as an energizer and, in general, to prolong life. Tea is made from young shoots and leaves of the plant Camellia sinensis (Willson and Clifford 1992;...

After water, tea is the world’s most widely consumed beverage. Tea is enjoyed by many people for its cooling and slightly bitter flavor and is known to have many particular health benefits [1-3]. There are several types of tea according to its fermentation processes such as black tea, oolong tea, white tea, yellow tea and green tea [4,5]. Green tea is, like many another type in general and gree...

The polyphenolic composition of Camellia irrawadiensis, which is a closely related species of Camellia sinensis (cultivated tea), was investigated. The most predominant polyphenol, a kind of ellagitannin, was isolated from leaves of C. irrawadiensis. Its structure was established as 1,2-di-O-galloyl-4,6-O-(S)-hexahydroxydiphenoyl-beta-D-glucose (2) on the basis of spectral and chemical evidence...

Streptomyces sp. XY006 is an endophytic bacterium isolated from the young leaf material of the tea plant (Camellia sinensis). The draft genome consists of 8.2 Mb and encodes 7,415 putative open reading frames. This strain is found to contain a high capacity for the production of natural products.

Endophytic Herbaspirillum sp. strain WT00C was isolated from tea plant (Camellia sinensis L.). Here, we report the 6.08 Mb draft genome sequence of this strain, providing bioinformation about its agronomic benefits and capability to reduce selenate/selenite into red elemental selenium.

Chemical analysis of the Sri Lankan tea (Camellia sinensis, L.) germplasm would immensely contribute to the success of the tea breeding programme. However, the polyphenols, particularly catechins (flavan-3-ols), are readily prone to oxidation in the conventional method of sample preparation. Therefore, optimization of the present sample preparation methodology for the profiling of metabolites i...
