Trimeric and Tetrameric A-Type Procyanidins from Peanut Skins.
Peanut skins are a rich source of oligomeric and polymeric procyanidins. The oligomeric fractions are dominated by dimers, trimers, and tetramers. A multistep chromatographic fractionation led to theExpand

The influence of procyanidins isolated from small-leaved lime flowers (Tilia cordata Mill.) on human neutrophils.
Linden flower is a wildly used plant material among patients in the treatment of common cold symptoms and mucosa inflammations. However, the structure and bioactivity of flavan-3-ol derivativesExpand

Crystal structure determination of an elusive methanol solvate – hydrate of catechin using crystal structure prediction and NMR crystallography
Experimental screening for new crystalline forms of a flavan-3-ol derivative, catechin, yielded several new solvates and solvate–hydrates of this polyphenol, among which a new methanol-containingExpand

Caffeic acid derivatives isolated from the aerial parts of Galinsoga parviflora and their effect on inhibiting oxidative burst in human neutrophils
Abstract Four new caffeoyl -glucaric and -altraric acid derivatives along with eleven known compounds were isolated from aerial parts of Galinsonga parviflora. Their structures were elucidated byExpand

A Multi-Technique Experimental and Computational Approach To Study the Dehydration Processes in the Crystals of Endomorphin Opioid Peptide Derivative
When molecular crystals undergo partial dehydration, determining the crystal contents and precise localization of the remaining water in the crystal lattice becomes challenging, especially when theExpand

Effects of Phytochemically Characterized Extracts From Syringa vulgaris and Isolated Secoiridoids on Mediators of Inflammation in a Human Neutrophil Model
Aim of the study: The aim of the present study was to investigate the effects of phytochemically characterized extracts connected with the traditional use (infusions and ethanolic extracts) ofExpand

Experimental tests for quality validation of computationally predicted crystal structures – a case of a conformationally flexible procyanidin A-2 dihydrate
Crystal structure prediction (CSP) of large, flexible, multi-component crystals is currently one of the most challenging computational tasks. In this work, we present a new approach to the CSPExpand
