MetabolomicsCharacterization of white tea metabolome: comparison against green and black tea by a nontargeted metabolomics approach
White tea is considered the least processed form of tea and is reported to have a series of potent bioactivities, such as antioxidant, anti-inflammatory, anti-mutagenic, and anti-cancer activities. However, the chemical composition of white tea and the dynamic changes of the metabolites during the m...

MetabolomicsMetabolite signatures of diverse Camellia sinensis tea populations
Tea plants (Camellia sinensis) present an excellent system to study evolution and diversification of specialized metabolites due to their abundance in classes, numbers and contents. A large number of tea cultivars have been cultivated throughout the world not only because of their adaption to differ...

MetabolomicsThe metabolite changes of Wolfberry (Lycium.) tea in different processing stages

Wolfberry (Lycium.) tea has a long history of consumption in China and is an important cash crop. Wolfberry tea can be made through five processes: picking, withering, fixation, stir-firing and extracting fragrance, which will correspond to the FWB, WWS, FWS, SFWS and EFWS groups, respectively. T...

MetabolomicsUntargeted food chemical safety assessment: A proof-of-concept on two analytical platforms and contamination scenarios of tea (Green tea study)
This study aims at assessing the capability of comparing and combining different instrumental platforms in an untargeted approach with a view of detecting chemical contaminants in food matrices at low levels. A strategy based on liquid chromatography-high resolution mass spectrometry (LC-HRMS) and c...

MetabolomicsPu-erh tea and theabrownin ameliorate metabolic syndrome in mice via potential microbiota-gut-liver-brain interactions
Metabolic syndrome (MS) is a common metabolic disorder characterized by obesity, insulin resistance, cardiovascular disease and gut microbiota dysbiosis. Pu-erh tea and its ingredient theabrownin have known functions on the reduction of body weight gain and fat accumulation. However, few studies sys...

MetabolomicsTheabrownin from Pu-erh tea attenuates hypercholesterolemia via modulation of gut microbiota and bile acid metabolism
Pu-erh tea displays cholesterol-lowering properties, but the underlying mechanism has not been elucidated. Theabrownin is one of the most active and abundant pigments in Pu-erh tea. Here, we show that theabrownin alters the gut microbiota in mice and humans, predominantly suppressing microbes associ...

MetabolomicsMetabolome analysis of tea leaves after transient overexpression of CsCHS1

Given that foliar diseases severely impact tea yield and quality, and prior research has shown that CsCHS1 positively regulates resistance to Didymella segeticola in tea leaves, we performed metabolomics analysis on tea leaves with transient overexpression of CsCHS1 to investigate the metabolites...

MetabolomicsUntargeted food contaminant detection using UHPLC-HRMS combined with multivariate analysis: Feasibility study on tea (Dataset 2 - Validation)
Powerful data pretreatment strategies inspired from the field of metabolomics were adapted to chemical food safety context to enable samples discrimination by multivariate methods based on low abundance ions. A highly automated workflow was produced. The open-source XCMS package was used and efficie...

MetabolomicsSexual Propagation Enhances Tea Quality Through Rhizosphere Microbiome Assembly and Metabolic Reprogramming in Camellia sinensis
Tea quality is primarily determined by the accumulation of specialized metabolites in fresh leaves; however, the mechanisms by which propagation methods influence tea qual-ity through plant–soil–microbiome interactions remain poorly understood. Here, sexually propagated (SR) and asexually propagated...
