Abstract
U ovome radu provedena je fitokemijska analiza svježih listova i grančica bijele imele (Viscum album L.) ubranih sa stabala na različitim lokacijama Republike Hrvatske i na komercijalno dostupnim proizvodima (čajevi). Kako bi se identificirale moguće prisutne skupine, metodom FTIR spektroskopije uzorci su analizirani su u različitim otapalima (etanol, metanol, voda ) u rasponu valnih duljina od 400 do 4000 cm-1. Rezultati FTIR spektroskopske analize ukazali su na postojanje različitih funkcionalnih skupina u ekstraktima metanola, etanola i vode. Maksimumi su u većini slučajeva bili najizraženiji u ekstraktima metanola, etanola, a potom u vodenim ekstraktima listova i grančica imele. Kako bi se odredile moguće sličnosti /razlike među uzorcima, na podatke dobivene FTIR spektroskopijom primijenjena je metoda analize glavnih komponenata (engl. Principal Component Analysis, PCA). Rezultati analize glavnih komponenata pokazali su da je na različitosti (sličnosti) među prikupljenim uzorcima najveći utjecaj imao zemljopisni položaj biljke.
Abstract (english)
In this paper, phytochemical analysis of fresh leaves and twigs of white mistletoe (Viscum album L.) harvested from trees in different locations of the Republic of Croatia and on commercially available products (teas) was performed. In order to identify possible groups present, by FTIR spectroscopy, the samples were analyzed in different solvents (ethanol, methanol, water) in the wavelength range from 400 to 4000 cm-1. The results of FTIR spectroscopic analysis indicated the existence of different functional groups in the extracts of methanol, ethanol and water. The maximums were in most cases most pronounced in the extracts of methanol, ethanol, and then in the aqueous extracts of mistletoe leaves and stems. In order to determine possible similarities/differences between samples, the Principal Component Analysis (PCA) method was applied to the data obtained by FTIR spectroscopy. The results of the principal components analysis showed that geographical differences had the greatest influence on differences (similarities) among collected samples plants.
