Dry matter, organic acids, ascorbic acid, minerals (nitrogen, phosphorus, potassium, calcium, magnesium, sodium) and polyphenolic profile of a number of non-traditional fruit species and their genotypes, namely blue honeysuckle (
Lonicera
spp.), Saskatoon berry (
Amelanchier alnifolia
), black mulberry (
Morus nigra
), Tomentosa cherry (
Prunus tomentosa
Thunb.) and jostaberry (
Ribes nigrum
x
Grossularia uva-crispa
) were investigated. The results showed that
Lonicera
genotypes displayed high levels of ascorbic acid and they were rich in minerals, with the cultivar ‘Amfora’ achieving the leading position in nitrogen, phosphorus and potassium content among all lesser known fruit species.
Amelanchier
cultivars represented a valuable source of ascorbic acid and calcium, ‘Tišňovský’ and ‘Smoky’ together with
Morus nigra
‘Jugoslavska’ accumulated the highest level of examined polyphenolic compounds. Regular consumption of studied less common fruit species can bring health benefits so they can represent a high potential value for fruit growers and in addition they can be utilised as functional foods.
