Abstract

Propolis je prirodna smolasta tvar, žute do tamnosmeđe boje, koju medonosne pčele (Apis mellifera) sakupljaju iz različitih biljnih izvora. Koristi se kao prirodni lijek još od antičkog doba pa sve do danas. Njegov kemijski sastav razlikuje se u uzorcima propolisa različitog geografskog i botaničkog podrijetla te je u njemu do sada identificirano više od 300 različitih spojeva. Propolis ne može biti korišten kao sirovina već se mora pročistiti ekstrakcijom otapalima, korištenjem raznih ekstrakcijskih metoda. Ovim postupkom uklanja se inertni materijal i izolira se polifenolna frakcija, koja uz ostale komponente doprinosi raznim biološkim svojstvima, koja su u ovom radu potkrijepljena rezultatima brojnih istraživanja. Među najvažnija svojstva propolisa ubrajaju se antimikrobna (antibakterijska, antifungalna, antivirusna), antiupalna, antioksidacijska i antitumorska svojstva.

Abstract (english)

Propolis is a natural resinous substance of yellow to dark brown colour, collected by honeybees (Apis mellifera) from various plant sources. It has been used as a natural remedy since ancient times and continues to be used today. Its chemical composition varies in samples of propolis from different geographical and botanical origins, over 300 different compounds have been identified in it so far. Propolis cannot be used as a raw material and must be purified by extraction using various extraction methods. This process removes inert material and isolates the polyphenolic fraction, which, along with other components, contributes to various biological properties supported by the results of numerous studies. The most important properties of propolis are its antimicrobial (antibacterial, antifungal, antiviral), anti-inflammatory, antioxidant, and antitumor effects.
