BACKGROUND/AIMS: Tea, produced from the evergreen Camellia sinensis, has reported therapeutic properties against multiple pathologies, including hypertension. Although some studies validate health benefits of tea, few have investigated molecular mechanisms action. The KCNQ5 voltage-gated potassium channel contributes to vascular smooth muscle tone and neuronal M-current regulation. METHODS: We ...

Germplasm conservation in the form of seed is convenient and most cost-effective ex situ conservation method for plant species producing orthodox seeds. Several species of plantation crops and spices produce non-orthodox seeds, which exhibit intermediate or recalcitrant seed storage behaviour. Storage of these species requires the use of in vitro conservation techniques for shortto medium-term ...

Sri Lanka, teardrop of India, besides being the largest exporter of tea (Camellia sinensis), in the world, has varied tropical terrain where many medicinal plants are collected from the wild and are cultivated. In a short-term, recently completed, focused training program, farmers’ societies met with field officers and professionals to share information and learn more about how to grow, harvest...

Three anthocyanins were isolated from the leaves of red flower tea (Benibana-cha), Camellia sinensis, and their structures were determined by means of chemical and spectroscopic analyses. Two are the anthocyanins, delphinidin and cyanidin 3-O-beta-D-galactosides, respectively. Whereas the third, delphinidin 3-0-beta-D-(6-(E)-p-coumaryl)galactopyranoside. The anthocyanins were also contained in ...

Tea plants (Camellia sinensis) are well known for their ability to accumulate high concentrations of aluminium (Al). Aluminium distribution in tea leaves has been previously estimated on a qualitative basis using energy dispersive X-ray microanalysis (EDXMA). However, no comprehensive studies have been carried out to quantitatively determine the distribution of Al, especially in young leaves wh...

Green tea ('Sencha'), made from the leaves of Camellia sinensis, is the most well-researched antioxidant beverage. The major source of its antioxidant activity is polyphenols, consisting mainly of catechins (flavan-3-ols). However, little is known about the physiological effects of green tea aroma, which lacks catechins. In the present study, we performed inhalation experiments with green tea a...

Tea (Camellia sinensis L.), an important drink and a natural medicine for thousands of years, contains many health beneficial compounds. Growing season, geographical region, and fermentation methods create many variations in tea compositions, which contribute to each tea's uniqueness. In this study, a simple, rapid, and efficient ultra-performance liquid chromatography (UPLC) method combined wi...

Leaves of tea (Camellia sinensis L.) contain extraordinary large amounts of (-)-epigallocatechin, (-)-epicatechin, (+)-gallocatechin, and (+)-catechin and derivatives of these compounds that show positive effects on human health. The health-promoting effects of flavan 3-ols, especially those of green tea, are of scientific and public interest. Furthermore, they play a crucial role in defense ag...
