Abstract
U ovom radu opisana je ekstrakcija polifenola iz lista i cvijeta bijelog gloga (Crataegus monogyna) metodom mikrovalne ekstrakcije. Ispitane su 30% i 50%-tna vodena otopina metanola, temperature 50° C i 65° C, te je mijenjano vrijeme ekstrakcije 3 min, 6 min, 9 min, 12 min i 15 min. Usporedbom svih rezultata najviše polifenola ekstrahirano je u 50%-tnoj vodenoj otopini metanola, pri temperaturi 50° C u trajanju od 9 minuta.
Abstract (english)
This study describes the extraction of polyphenols from the leaves and flowers of white hawthorn (Crataegus monogyna) with method of microwave extraction. Used as 30% strength and 50% aqueous methanol, the temperature of 50° C and 65° C, and the extraction time was 3 min, 6 min, 9 min, 12 min and 15 min. By comparing the results, the most polyphenols were extracted in 50% aqueous methanol at a temperature of 50° C for 9 minutes.
