A simple method for the isolation and purification of alpha-galactosides, raffinose family oligosaccharides (RFOs), from legumes has been developed. The method includes (i) imbibition of seeds, (ii) extraction with 50% ethanol, (iii) precipitation of RFOs, (iv) purification of RFOs on diatomaceous earth and charcoal, and (v) cation-exchange chromatography.(More)
The woody Amazonian vine Uncaria tomentosa (cat's claw) has been recently more and more popular all over the world as an immunomodulatory, antiinflammatory and anti-cancer remedy. This study investigates anti-proliferative potency of several cat's claw preparations with different quantitative and qualitative alkaloid contents on HL-60 acute promyelocytic(More)
The antioxidant properties of aqueous and ethanolic extracts of the Uncaria tomentosa bark were evaluated. The analysis included trolox equivalent antioxidant capacity (TEAC), peroxyl radical-trapping capacity (PRTC), superoxide radical scavenging activity (SOD) and quantitation of total tannins (TT) and total phenolic compounds (TPC). The obtained results(More)
Abiotic stresses, including low temperature, can significantly reduce plant yielding. The knowledge on the molecular basis of stress tolerance could help to improve its level in species of relatively high importance to agriculture. Unfortunately, the complex research performed so far mainly on model species and also, to some extent, on cereals does not(More)
In this study, proteomic and metabolomic changes in leaves and roots of two barley (Hordeum vulgare L.) genotypes, with contrasting drought tolerance, subjected to water deficit were investigated. Our two-dimensional electrophoresis (2D-PAGE) combined with matrix-assisted laser desorption time of flight mass spectrometry (MALDI-TOF and MALDI-TOF/TOF)(More)
The results of studies on the content of the nitrogen basic compounds, viz. quinolizidine alkaloids, biogenic polyamines and basic amino acids in lupin seeds are presented. The investigations concerned three lupin species (Lupinus angustifolius L., Lupinus albus L. and Lupinus luteus L.) and 10 bitter and sweet cultivated varieties. Content of quinolizidine(More)
Drought stress is perhaps one of the most common abiotic factors which crop plants have to cope with. To survive, plants have to adapt to periods of water deficit that may occur during their vegetation. This can be achieved by triggering various changes in the plant genome, transcriptome, proteome, and metabolome, leading to different physiological and(More)
