Abstract
Obalni petrovac (Crithumum maritimum L.) je višegodišnja halofitna biljka iz porodice štitarki (Apiaceae). Raste na priobalnim podruĉjima Mediterana, Crnog mora te Atlantskog oceana. Kroz povijest se petrovac u narodnoj medicini koristio kao lijek, a danas predstavlja veliki potencijal za prehrambenu i farmaceutsku industriju zbog visokog sadržaja bioaktivnih komponenti. Cilj ovog rada bio je odrediti spektrofotometrijski udio ukupnih fenola i antioksidacijsku aktivnost ekstrakata cvijeta petrovca sa deset razliĉitih lokacija duž Jadranske obale, pomoću metode redukcije 2,2-difenil-1-pikrilhidrazil radikala (engl. 2,2-Diphenyl-1-picrylhydrazyl, DPPH) i metode odreĊivanja snage redukcije željeza (engl. Ferric Reducing Antioxidant Power, FRAP). Koncentracija klorogenske kiseline i njezinih derivata odreĊena je tekućinskom kromatografijom visoke djelotvornosti (engl. High Performance Liquid Chromatography, HPLC) sa UV/Vis detektorom. Rezultati su pokazali da cvjetovi petrovca sadrže visok udio ukupnih fenola te posjeduju izrazitu antioksidacijsku aktivnost što potvrĊuje potencijal iskoristivosti ne samo listova, već i cvjetova biljke. Najvišu koncentraciju fenolnih kiselina i antioksidacijsku aktivnost pokazao je uzorak sakupljen na podruĉju Senja, a najnižu uzorci sakupljeni na podruĉju Cavtata i Splita.
Abstract (english)
Sea fennel (Crithmum maritimum L.) is a perennial halophytic plant of the umbellifers family (Apiaceae). It grows along the coastal areas of the Mediterranean, the Black Sea and the Atlantic Ocean. Throughout history, it has been used in folk medicine, but today it represents a great potential for the food and pharmaceutical industries due to its high content of bioactive compounds. The aim of this work was to determine by spectrometry the content of total phenolics and the antioxidant activity of sea fennel flower extracts from ten different locations along the Adriatic coast using the method of reduction of 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assay. The concentrations of chlorogenic acid and its derivatives were determined using High Performance Liquid Chromatography (HPLC) with UV/Vis detector. The results showed that sea fennel flowers contain a high content of total phenolics and have good antioxidant activity, which confirms the potential of use not only the leaves, but also the flowers of sea fennel. The sample collected in Senj had the highest concentration of phenolic acids and antioxidant activity, while the samples collected in Cavtat and Split areas had the lowest concentration.
