Abstract

Dehidracetna kiselina (DHA) i njeni derivati su važni spojevi koji se najčešće koriste kao konzervansi i antimikrobni agensi. DHA ima široku upotrebu u prehrambenoj i farmaceutskoj industriji te u organskim sintezama. Kumarini su skupina organskih spojeva koja se prirodno pojavljuje u mnogim vrstama biljaka. Osim kao aditivi, primjenu su našli i u sintezi lijekova. U ovom radu istraživana je antimikrobna aktivnost derivata dehidracetne kiseline i kumarina. Da bi se odredila osjetljivost bakterija, kvasaca i plijesni korištena je difuzijska tehnika, a istraživanja su provedena sa različitim koncentracijama istraživanih spojeva. Dokazano je da istraživani spojevi u određenim koncentracijama inhibiraju rast odabranih sojeva mikroorganizama.

Abstract (english)

Dehydroacetic acid (DHA) and its derivates are an important class of compounds which are used as preservatives and antimicrobial agents.DHA is beeing used in food and pharmaceutic industry, and in organic synthesis. Coumarins are a group of organic compounds which are naturally nascent in many kinds of plants. Coumarins are used as additives and in drug synthesis. Synthetized derivates of dehydroacetic acid and coumarin were tested for antimicrobial activity. To determine the sensitivity of bacteria, yeasts and moulds, the diffusion technique was used. Research was done with different concentration of researched compounds. It has been proven that researched compounds inhibit the growth of chosen microorganisms at certain concentrations.
