Abstract
Alzheimerova bolest je jedna od najčešćih degenerativnih bolesti mozga, a karakterizira ju oštećenje živčanih stanica i propadanje kognitivnih funkcija. Pravi lijek nije poznat, ali se najčešće primjenjuju inhibitori acetilkolinesteraze. U ovom radu kao potencijalni inhibitori ispitana su eterična ulja đumbira (Zingiber officinale Roscoe) i celera (Apium graveolens L.). Kako bi se utvrdila potencijalna inhibicijska sposobnost ispitivanih ulja korištena je modificirana spektrofotometrijska metoda po Ellmanu. Prema dobivenim rezultatima vidljivo je da eterično ulje đumbira nema inhibicijskih sposobnosti, dok eterično ulje celera pokazuje inhibicijsku aktivnost ovisno o koncentraciji ispitivane otopine. Ulja su također ispitivana i na antioksidacijsku aktivnost pomoću DPPH i FRAP metoda te se prema dobivenim rezultatima može zaključiti da ni jedno od ispitivanih ulja nema značajnu antioksidativne sposobnosti. Sastav eteričnih ulja određen je GC-MS analizom te su se kao najzastupljeniji spojevi u eteričnom ulju celera pokazali limonen, β-selinen, sedanenolid, 3-n-butilftalid, α-selinen, dok su kod eteričnog ulja đumbira to α-zingiberen, β-seskvifelandren, β-bisabolen te α-kurkumen.
Abstract (english)
Alzheimer's disease is one of the most common degenerative diseases of the brain, and it is characterized by damage to nerve cells and deterioration of cognitive functions. The exact drug is not known, but acetylcholinesterase inhibitors are most used. In this work, the essential oils of ginger (Zingiber officinale Roscoe) and celery (Apium graveolens L.) are tested as potential inhibitors. A modified Ellman spectrophotometric method was used to determine the potential inhibitory ability of the tested oils. According to the obtained results, it is evident that ginger essential oil has no inhibitory abilities, while celery essential oil shows inhibitory activity depending on the concentration of the test solution. The oils were also tested for antioxidant activity using DPPH and FRAP methods, and according to the obtained results, it can be concluded that none of the tested oils has significant antioxidant capacity. The composition of essential oils was determined by GC-MS analysis, and the most common compounds in celery essential oil were limonene, β-selinene, sedanenolide, 3-n-butylphthalide, α-selinene, while in ginger essential oil it was α-zingiberene, β-sesquifelandrene, β-bisabolene and α-curcumene.
