Elderberry contains healthy low molecular weight nutraceuticals and lectins which are sequence-related to the elderberry allergen Sam n1. Some of these lectins are type II ribosome-inactivating proteins. The sensitivity of native lectins present in elderberry fruits and bark to the proteolysis triggered by in vitro simulated gastric and duodenal fluids has been investigated. It was found that these lectins are refractory to proteolysis. Nonetheless, incubation for 5-10 min in a boiling water bath completely sensitized them to the hydrolytic enzymes in vitro...

BACKGROUND: Elderberry (Sambucus nigra L.) possesses high antioxidant activity and has been used to treat numerous medicinal disorders. In addition to their antioxidant properties, elderberry parts accumulate toxic cyanogenic glycosides (CGG). It has been proven that altitude influences the biosynthesis of many secondary metabolites. In the present study we investigated the change of phenolics and CGG in elder leaves, flowers, and berries induced by different altitudes and locations. RESULTS: The data indicate that the accumulation of CGG and phenolics is affected by the altitude of the growing site...

Fruit pomace remaining after juice extraction is still a source of bioactive compounds. Especially rich in these compounds is the pomace from blackcurrant fruit and from fruits of little-known horticultural plants, like: rowan, rosehip and elderberry. The addition of fruit pomace to bakery and confectionery products, especially to those made of white flour, may significantly enrich their composition with dietary fiber, vitamins and phenolic compounds. This study was aimed at determining the effect of 20 % addition of fruit pomace from rosehip, rowan, blackcurrant and elderberry on the properties of shortbread cookies...

Five new carlaviruses infecting elderberry were characterized and tentatively named as elderberry virus A-E (ElVA-ElVE). Their genome organization is similar to that of other carlaviruses with size ranging from 8540 to 8628 nucleotides, excluding the polyadenylated tails. ElVA, ElVB and ElVD share a common ancestor as do ElVC and ElVE, indicating that speciation may be sympatric with all viruses having emerged in elderberry. Analyses of the carlavirus conserved domains indicate that the 2-oxoglutarate and Fe(II)-dependent oxygenase motifs are reliable indicators of virus phylogenetic classification with recombination playing a significant role in the evolution of the genus...
