Abstract

. (2017). Nontargeted metabolite profiling highlights the potential of strawberry leaves as a resource for specific bioactive compounds.

Phenolic compounds in strawberry (Fragaria x ananassa Duch.) microshoots

“…Phenolic composition of strawberry leaves of cultivar 'Solnechnaya Polyanka' in the South of Western Siberia consists of phenolic acids (gallic, caffeic, p-coumaric, and ferulic acids), ellagic acid and its derivatives, and quercetin and kaempferol glycosides. This composition generally corresponds with that of previously studied samples of other F. × аnanassa cultivars [4][5][6]. Phenolic composition of in vitro plants is similar to that of field-grown plants, and it is characterized by trace amounts of flavonoid glycosides and higher, than in field-grown plants, concentrations of certain phenolic acids.…”

“…Ellagic and gallic acids, their derivatives; vanillic, p-hydroxybenzoic, caffeic, chlorogenic acids, as well as flavonols: quercetin, kempferol, myricetin and their glycosides, including rutin, were found in strawberry leaves. Meanwhile, ellagic acid derivatives can constitute up to 50% of phenolic compounds [4,5]. Flavonoid concentrations also reached significant values (up to 30% of total phenolic content) [6,7].…”

Answering biological questions by analysis of the strawberry metabolome

“…Metabolite profiling analysis in strawberry leaves in combination with antioxidant measurement was performed to identify natural products that are accountable for the antioxidant activity of the extracts (D’Urso et al 2018). LC–MS was also utilized to study the differences and commonalities between the metabolite profiles in leaves (Kårlund et al 2017). In general, strawberry leaves contained high levels of quercetin and kaempferol derivatives, caffeic and chlorogenic acid derivatives, and ellagitannins as well as octadecatrienoic acid derivatives.…”

1H-NMR based metabolomics reveals the nutrient differences of two kinds of freshwater fish soups before and after simulated gastrointestinal digestion

“…Metabolomic analyses have generally been classified as targeted or untargeted approaches. The targeted analyses are known to focus on a specific or small group of intended metabolites that in most cases require accurate quantification 12,13 , and the untargeted or comprehensive metabolomics focus on the detection of as many metabolites as possible in order to obtain the patterns or fingerprints without focusing on specific compounds 14,15 . The NMR method has been shown to be one of the most robust methodologies through using various technologies for metabolite profiling, especially for a comprehensive analysis of primary food metabolites.…”
