Kombucha is a refreshing beverage obtained by the fermentation of sweetened black tea with a „tea fungus“ (symbiotic culture of acetic acid bacteria and yeasts). It is consumed due to its potential beneficial effects on human health. The aim of this study was to investigate activity of Kombucha on human peripheral blood lymphocytes in vitro. We analyzed Kombucha made from different substrates: ...

The aim of this study was to investigate the antioxidant properties of the ethanol extract of the flower of Camellia japonica (Camellia extract). Camellia extract exhibited 1,1-diphenyl-2-picrylhydrazyl radical and intracellular reactive oxygen species (ROS) scavenging activity in human HaCaT keratinocytes. In addition, Camellia extract scavenged superoxide anion generated by xanthine/xanthine ...

Paenibacillus sp. XY044 is an endophytic bacterium isolated from the stem of a tea plant (Camellia sinensis cv. Maoxie). Here, we present the draft genome sequence of XY044, which includes genes encoding features related to plant growth promotion and biocontrol.

OBJECTIVE To evaluate fluoride and aluminum concentration in herbal, black, ready-to-drink, and imported teas available in Brazil considering the risks fluoride and aluminum pose to oral and general health, respectively. METHODS One-hundred and seventy-seven samples of herbal and black tea, 11 types of imported tea and 21 samples of ready-to-drink tea were divided into four groups: I-herbal t...

In the present study, sequential extracts of Camellia sinensis, Glycyrrhiza glabra, Calendula officinalis and Linum usitatissimum were analyzed for their antioxidant activity in different test systems. Phytochemical analysis indicated that amongst twelve test extracts, methanolic extract of Camellia sinensis was found to have the highest total phenolic content (104.93 ± 1.630 mg GAE /g) and FRA...

Tea is one of the most popular beverages across the world and is made exclusively from cultivars of Camellia sinensis. Many wild relatives of the genus Camellia that are closely related to C. sinensis are native to Southwest China. In this study, we first identified the distinct genetic divergence between C. sinensis and its wild relatives and provided a glimpse into the artificial selection of...

MADS (Minichromosome Maintenance1 Agamous Deficiens Serum response factor) box genes encode transcription factors and they play a key role in growth and development of flowering plants. There are two types of MADS box genes- Type I (serum response factor (SRF)-like) and Type II (myocyte enhancer factor 2 (MEF2)-like). Type II MADS box genes have a conserved MIKC domain (MADS DNA-binding domain,...

Two new alcoholic aroma precursors, cis- and trans-linalool, 3,7-oxides 6-O-beta-D-apiofuranosyl-beta-D-glucopyranosides (1 and 2), as well as two already known compounds, (Z)-3-hexenyl beta-D-glucopyranoside (3) and methyl salicylate 6-O-beta-D-xylopyranosyl-beta-D-glucopyranoside (beta-primeveroside: 4), and another new monoterpendiol glycoside, 8-hydroxygeranyl beta-primeveroside (5) have re...
