Abstract:Cianogeni glikozidi so prisotni v vsaj 2.500 taksonomskih skupinah različnih rastlinskih družin, ki vključujejo številne gospodarsko pomembne sadne vrste. Koncentrirajo se v semenih plodov in lahko predstavljajo tveganje za zdravje ljudi, ker se pri hidrolizi sprošča cianid. V naši raziskavi smo s pikratno metodo določili vsebnost skupnega cianida v koščicah češenj (Prunus avium L.), sliv (Prunus domestica L.) in ringlojev (Prunus domestica subsp. italica (Borkh.) Gams). Najnižjo vsebnost (19,6 µg/g) smo izmerili v koščicah akcesije češnje R x L 98 in najvišjo (310 µg/g) v akcesiji ringloja 6319. Znatne razlike v vsebnosti cianida smo zabeležili tudi znotraj sadnih vrst s koeficienti variacije 56,9 % pri češnjah, 54,4 % pri slivah in 30,5 % pri ringlojih. Primerjava srednjih vrednosti sadnih vrst je pokazala, da je vsebnost cianida v koščicah ringlojev statistično značilno višja kot v koščicah sliv in češenj.

Title:Cyanide Contents in Pits of Cherries, Gages and Plums Using a Modified Sensitive Picrate Method
Abstract:Cyanogenic glycosides are present in at least 2500 taxonomic groups of different plant families, including many economically important fruit species. They are most concentrated in the seeds of fruits and may pose a risk to human health due to the release of cyanide. In the present study, we compared the cyanide content in the pits of cherries (Prunus avium L.), plums (Prunus domestica L.), and gages (Prunus domestica subsp. italica (Borkh.) Gams) using the picrate paper method. The lowest cyanide content (19.6 µg/g) was found in a cherry accession (R x L 98), and the highest (310 µg/g) in a gage accession (Gage 6319). Considerable variation in cyanide content was found within varieties of a fruit tree species, reaching a coefficient of variation of 56.9% for cherries, 54.4% for plums, and 30.5% for gages. Looking at the overall medians, the results show that the cyanide content in the pits of gages was significantly higher than the cyanide content in the pits of plums and cherries.
