Abstract
Jagoda (Fragaria ananassa × Duch.) predstavlja bogat izvor biološki i farmakološki aktivnih polifenolnih spojeva koji imaju pozitivan učinak na zdravlje čovjeka. Cilj ovog rada je ispitati biološki učinak jagode na različitim biološkim sustavima uključujući humane stanične linije predstavnike mikroflore čovjeka (Escherichia coli, Lactobacillus fermentum, Staphylococcus aureus), i modelnu DNA, plazmid phiX174. U tu svrhu korištene su metode Neutral red za određivanje citotoksičnosti ekstrakta na humanim staničnim linijama, DCFH-DA za određivanje prooksidacijskog/antioksidacijskog djelovanja na humanim staničnim linijama, agarozna elektroforeza za određivanje genoprotektivnog učinka te protokol za utvrđivanje antimikrobnog djelovanja ekstrakta. Dobiveni rezultati pokazali su da vodeni ekstrakt jagode djeluje citotoksično na staničnu liniju adenokarcinoma debelog crijeva i karcinoma epitela usne šupljine. Ekstrakt jagode nije pokazao antioksidacijsko djelovanje niti na ijednoj staničnoj liniji. Utvrđen je i genoprotektivni učinak jagode na modelnoj DNA. Biološki aktivni spojevi u ekstraktu jagode pokazali su antimikrobnu aktivnost prema Gram-pozitivnim bakterijama, L. fermentum i S. aureus.
Abstract (english)
Strawberry (Fragaria ananassa × Duch.) is a source of biologically and pharmacologically active polyphenols that have beneficial effects on human health. The aim of this work is to investigate the biological effect of strawberry extract on different biological systems, including human cell lines, human microflora (Escherichia coli, Lactobacillus fermentum, Staphylococcus aureus), and model DNA, plasmid phiX174. Various methods were used, including Neutral red to determine cytotoxicity to human cell lines, DCFH-DA to determine prooxidant/antioxidant effect on human cells, agarose electrophoresis to determine genoprotective effect, and a protocol to determine antimicrobial effect of the extract. The results showed that the strawberry extract has a cytotoxic effect on adenocarcinoma cells of the colon and epithelial carcinoma cells of the oral cavity. The strawberry extract showed no antioxidant effect on any of the cell lines studied. The strawberry extract showed genoprotective effect on the model DNA. Biologically active compounds in the extract showed antimicrobial activity against Gram-positive bacteria, L. fermentum and S. aureus.
