Screening of mango (Mangifera indica L.) cultivars for their contents of flavonol O- and xanthone C-glycosides, anthocyanins, and pectin.
TLDR
The profile of flavonol glycosides of the peels proved to be highly characteristic and may therefore serve as a tool for authenticity control of mango puree concentrate, which is often produced from unpeeled fruits and represents an important intermediate for the production of mango nectars.
Biochemical Conservation and Evolution of Germacrene A Oxidase in Asteraceae*
TLDR
The observed amorphadiene oxidase activity in GAOs suggests that the catalytic plasticity is embedded in ancestral GAO enzymes that may contribute to the chemical and catalytic diversity in nature.
Enzymatic production and complete nuclear magnetic resonance assignment of the sugar lactulose.
TLDR
Lactulose was unambiguously proved to be the major transglycosylation disaccharide and its molecular structure was investigated in detail and confirmed after purification of the reaction solution by LC-MS and 1D and 2D NMR.
Effects of tillage and crop rotation on chemical phosphorus forms and some related biological activities in a Chilean Ultisol
The effect of tillage systems and crop rotation on microbial biomass phosphorus (MBP) and acid phosphatase (P‐ase) activity, and the amount of different phosphorus (P) forms measured by 31P‐NMR
Formation Pathways for Lysine-Arginine Cross-links Derived from Hexoses and Pentoses by Maillard Processes
TLDR
From these results it seems fully justified to expect both glucosepane 9 and DOGDIC 12 to constitute important in vivo cross-links.
Elution order of quercetin glycosides from apple pomace extracts on a new HPLC stationary phase with hydrophilic endcapping
A stationary phase with hydrophilic endcapping was used for the separation of seven quercetin (Q) glycosides by high-performance liquid chromatography. The elution order was established as Q
A Structural and Functional Elucidation of the Rumen Microbiome Influenced by Various Diets and Microenvironments
TLDR
Proteins involved in carbon metabolism were detected in high numbers and identification of metabolites like short-chain fatty acids, methylamines and phenylpropionate by NMR enabled linkage between producers and products.
Detection of phloridzin in strawberries (Fragaria x ananassa Duch.) by HPLC-PDA-MS/MS and NMR spectroscopy.
TLDR
This first report on the occurrence of phloridzin in strawberries is of particular interest for the authenticity control of strawberry products such as juices, jams, and fruit preparations since phlorodzin has so far been used for the detection of fraudulent admixtures.
