Sažetak
Geographical position of Croatia assures abundant vegetation with over 1000 different varieties of wild plants that could be used in human nutrition. The blackthorn, is a large shrub or a small tree of the genus Prunus in the Rosaceae family, botanically Prunus spinosa. Its fruit is cherry blak blueish, and it called the sloe, wild plum, blackthorn, prunellier, endrino etc. (Marakoglu et al., 2005). Sloes are very bitter until they have been caught by the first heavy frost of winter. Wild plum has been used as a traditional medicine for centuries in Europe. In folk medicine, wild plum is used as a laxative and a remedy for cramps, bloating, indigestion, and diarrhea. Wild plums can also be eaten liberally as foods or processed into jams, nectars, syrups, wine, liqueurs etc. Wild plum fruits contains: coumarins, flavonoids, nor-isoprenoid glycosides and proanthocyanidins (Kumarasamy, 2004). Generally, there is not data in literature about polyphenols as biologically active compounds in wild plum's fruits. Therefore, the aims of this study were to examine changes in physico-chemical composition and different groups of polyphenols during ripening of the wild plum and to determine optimal time for harvesting and processing. The aim was also to evaluate total antioxidant activity by using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method.
