Abstract

Kromatografija je skup separacijskih tehnika koje služi za odjeljivanje, identifikaciju i kvantitativno određivanje sastojaka smjese. Kao najupotrebljivanija tehnika ističe se tekućinska kromatografija visoke djelotvornosti (HPLC). Vitamin C pripada skupini vitamina topljivih u vodi. Vrlo je jak antioksidans, blagotvorno djeluje na zdravlje čovjeka i jedan je od najistraživanijih vitamina. Najbolji izvori vitamina C su voće i povrće. Ovaj rad opisuje rezultate istraživanja udjela vitamina C u komercijalnim sokovima od rajčice, cikle, mrkve i kiselog kupusa određenog HPLC metodom. Udio vitamina C u sokovima od rajčice kretao se u rasponu od ispod limita kvantifikacije (< LOQ) do 8,67 mg/100 mL, u sokovima od cikle od < LOQ do 23,26 mg/100 mL, u sokovima od mrkve od < LOQ do 36,19 mg/100 mL te u sokovima od kiselog kupusa u rasponu od 13,39 mg/100 mL do 16,54 mg/100 mL. Chromatography is a set of techniques used for separation, identification and quantitative determination of the mixture components. The most used one is high performance liquid chromatography (HPLC). Vitamin C belongs to a group of water-soluble vitamins. It is a very strong antioxidant with a beneficial effect to human health. It is also one of the most explored vitamins. The most important sources of vitamin C are fruits and vegetables. This paper describes the results of the study on vitamin C content in commercial tomato, beetroot, carrot and sour cabbage juices determined by HPLC method. Vitamin C content in tomato juices was found to range from below the quantification limit (< LOQ) to 8.67 mg/100 mL, in beetroot juices from < LOQ to 23.26 mg/100 mL, in carrot juices from < LOQ to 36.19 mg/100 mL and in sour cabbage juices from 13.39 mg/100 mL to 16.54 mg/100 mL.
