Abstract
Avokado kao klimakterijsko voće dozrijeva nakon berbe te za posljedicu toga sadrži različite koncentracije antioksidativnih komponenti, ključnih u zaštiti ljudskog organizma od negativnog utjecaja slobodnih radikala, u zrelom i nedozrelom plodu. Cilj ovog istraživanja bio je usporediti koncentracije fenola i flavonoida u ispitivanim uzorcima zrelog i nedozrelog ploda avokada. Nakon postupka ekstrakcije, uklanjanja etanola i liofilizacije dobiveni su uzorci podvrgnuti spektrofotometrijskim metodama pomoću kojih su koncentracije navedenih antioksidansa izmjerene. Najveći udio fenola pronađen je u sjemenci zrelog avokada, dok flavonoida u sjemenci nezrelog avokada. Najmanje koncentracije fenola i flavonoida zabilježene su upravo u pulpi, dijelu ploda koji se najviše konzumira u čovjekovoj prehrani.
Abstract (english)
Avocado, as a climacteric fruit ripens after harvest and therefore contains different concentrations of antioxidant components in ripe and unripe fruits, which are crucial for protecting the human body from the negative effects of free radicals. The aim of this study was to compare the concentrations of phenols and flavonoids in the studied samples of ripe and unripe avocado fruit. After the extraction process, ethanol removal and freeze-drying, the obtained samples were subjected to spectrophotometric methods that measured the concentrations of these antioxidants. The highest level of phenols was found in ripe avocado seed, while flavonoids in unripe avocado seed. The lowest concentrations of both antioxidants were found in the pulp, the part of the fruit most consumed in the human diet.
