BACKGROUND Recently, tea (Camellia sinensis) flowers have attracted increasing interest because of their content of bioactive compounds such as catechins. The aim of this study was to investigate the occurrence of some characteristic compounds in tea flowers. RESULTS A principal component analysis of metabolites using ultra-performance liquid chromatography/time-of-flight mass spectrometry sh...

Cold environment is the main constraint for tea plants (Camellia sinensis) distribution and tea farming. We identified two tea cultivars, called var. sinensis cv. Shuchazao (SCZ) with a high cold-tolerance and var. assamica cv. Yinghong9 (YH9) with low cold-tolerance. To better understand the response mechanism of tea plants under cold stress for improving breeding, we compared physiological an...

Green tea, prepared from the leaves of Camellia sinensis L., is a beverage that is popular worldwide. Polyphenols in green tea have been receiving much attention as potential compounds for the maintenance of human health due to their varied biological activity and low toxicity. In particular, the contribution of antioxidant activity to the prevention of diseases caused by oxidative stress has b...

An experimental research to study the effect of plucking cycles on the physiological pattern of leaf growth of tea plant of newly-released tea cultivated varieties (clones) was conducted at Plantation of the Research Centre for Tea and Quinine Trees of Gambung of Bandung, Indonesia from April 2012 to July 2012. The leaf growth of tea are dependent on several genetic and environmental/agronomic ...

Extracts of tea (Camellia sinensis) can reverse methicillin resistance in methicillin-resistant Staphylococcus aureus (MRSA) and also, to some extent, penicillin resistance in beta-lactamase-producing S. aureus. These phenomena are explained by prevention of PBP2' synthesis and inhibition of secretion of beta-lactamase, respectively. Synergy between beta-lactams and tea extracts were demonstrat...

Over 10 centuries, ancient cultivated tea populations (Camellia sinensis var. assamica) are still planted merely in Yunnan province of China. Genetic diversity and differentiation were examined in 10 ancient tea plantations by using ISSR markers. The average genetic diversity within populations, estimated with Nei's genetic diversity (HE), was approximately 0.2809, while Shannon indices (HO) wa...

Tea, the most commonly consumed non-alcoholic beverages is known for its aroma, taste and putative physiological functions. Its richness in flavonoids and other polyphenols had shown a wide range of biological and pharmaceutical benefits. Fatty liver disease is a metabolic syndrome characterized by large vacuoles of triglycerides accumulated in the liver cells by the process of steatosis. Prese...

Characteristic secondary metabolites, including flavonoids, theanine and caffeine, are important components of Camellia sinensis, and their biosynthesis has attracted widespread interest. Previous studies on the biosynthesis of these major secondary metabolites using next-generation sequencing technologies limited the accurately prediction of full-length (FL) splice isoforms. Herein, we applied...

Tea is one of the most widely consumed beverages in world next to water. It made from tea leaves Camellia sinensis. Herbal teas on other hand, are variants not sinensis but plants, herbs, roots and plant extract. This study therefore, investigated quality acceptability herbal dried Moringa lemon peel powder. were 100% leaves, powder blends ratios 50:50, 30:70 60:40. A total five formulations ob...

This review examined the use of green tea (Camellia sinensis) in the diets of poultry. Research findings were obtained from various recent studies, where much attention was focused on the role of green tea in the promotion of both animal and human health. The review involved some of the currently available information about green tea, pertaining to its chemical composition, anticoccidial and an...
