Raddi-Untargeted Metabolomics Approach to Investigate the Chemical Variation in Volatile and Non-Volatile Compounds.

Context: Raddi is used in Brazilian folk medicine due to the wound healing and antiseptic properties of its bark, and its fruit are used as a condiment. However, the aerial parts of this plant have been studied and present some bioactive compounds as well.

Objectives: The aim of this study was to investigate the variation in volatile and non-volatile composition of leaves using untargeted metabolomics.

Wine metabolome and sensory analyses demonstrate the oenological potential of novel grapevine genotypes for sustainable viticulture in warm climates.

Background: Genetic breeding is essential to develop grapevine genotypes adapted to warm climates and resistant to pathogens. Traditionally cultivated Vitis vinifera is susceptible to biotic and abiotic stresses. Winemakers and consumers, however, perceive wines from non-vinifera or hybrid cultivars as inferior.

Metabolite profiling reveals the influence of grapevine genetic distance on the chemical signature of juices.

Background: Yield, disease tolerance, and climate adaptation are important traits in grapevine genetic breeding programs. Selection for these characteristics causes unpredictable changes in primary and specialized metabolism, affecting the physicochemical properties and chemical composition of the berries and their processed products, juice, and wine. In this study, we investigated the influence of the genetic distance between grapevine genotypes on the chemical signatures of the juices, by integrating comprehensive metabolic profiling to genetic analyses.

Simultaneous UHPLC-MS Quantification of Catechins and Untargeted Metabolomic Profiling for Proof-of-Concept Authenticity Determination of ssp. Samples.

Due to the widespread use of leaves in the treatment of gastric ulcers, herbal medicines derived from such species are distributed by the national health system in Brazil. A related species, , is also used for the same disorders, and both are popularly known as . Due to their popular use, the quality and efficiency of the herbal medicines derived from these species is an important public health issue.
