AB  - Cocoa beans are part of the cocoa plant fruit (Theobroma cacao L.) used to prepare various
products such as chocolate, cocoa butter, jelly, liqueurs, cosmetics, etc. Dark chocolate is consumed
worldwide by different populations and is known for its good taste, making it one of the most
favoured food products. This work aimed to determine the content of total polyphenols (TPC), total
flavonoids (TFC), and the antioxidant potential measured through the ability to scavenge DPPH
free radicals (DPPH), ferric reducing power (FRAP), and total antioxidant capacity (TAC), as well as
major and trace elements contained in twelve commercially available dark chocolate samples, with
cocoa content ranging from 40% to 99%. The total polyphenols content ranged between 10.55 and
39.82 mg/g GAE, while the total flavonoid content was from 10.04 to 37.85 mg/g CE. All applied
antioxidant assays indicate that the sample with the highest cocoa percentage shows the greatest
antioxidant activity (DPPH: 48.34% of inhibition; FRAP: 89.00 mg/g GAE; TAC: 83.86 mg/g AAE).
Statistical methods were applied to establish the differences between the samples concerning TPC,
TFC, DPPH, FRAP and TAC, as well as to differentiate the samples according to the mineral content.
The results indicated that the differences in TPC and TFC between different samples depended on
the cocoa content and the addition of dried fruit pieces. A good correlation between antioxidant
potency composite index (ACI) and declared cocoa content was noticed (R
2 = 0.8034), indicating
that the declared percentage of cocoa is a reliable indicator for antioxidant activity of analysed dark
chocolate samples. The nutritional evaluation proved that the studied chocolate samples were an
excellent source of Mg, Fe, Mn and Cu.

AB  - U okviru ovog rada izvršeno je preliminarno ispitivanje kvaliteta prirodnih mineralnih voda sa teritorije Vrnjačke Banje (U1-U7) određivanjem osnovnih fizičko-hemijskih  parametara kao što su: temperatura, pH vrednost, provodljivost, mutnoća, sadržaj hlorida i ukupnih organskih materija, kao i sadržaj amonijaka. Posebna pažnja stavljena je na ispi tivanje sadržaja odabranih makro - i mikroelemenata za čije određivanje je korišćena ana litička tehnika induktivno kuplovana plazma sa optičkom emisionom spektrometrijom, ICP-OES (eng. Inductively coupled plasma - optic emission spectrometry). Koncentracije makroelemenata Ca, Mg i Si u analiziranim uzorcima bile su u granicama dozvoljenih vrednosti, dok je višestruko povišena koncentracija Na detektovana u uzorcima U2, U3, U5 i U7. Povišene koncentracije mikroelemenata zabeležene su u uzorcima: U6 (As); U3-U5 (Se); U1 i U4 (Fe); U1-U4 i U7 (Mn), dok koncentracije ostalih mikroelemenata (S, Ni, Cd) su bile u okviru dozvoljenih vrendosti po Pravilniku o ispravnosti vode za ljudsku upotrebu.
AB  - In this paper preliminary tests of the quality of natural mineral waters from the Vrnjacka Banja area (U1-U7) were carried out by determining basic physical and chemical parameters such as: temperature, pH value, conductivity, turbidimetry, content of chloride and total organic substances, as well as the content of ammonia. Particular attention was paid to testing the content of selected macro- and microelements by using analytical techniques inductively purchased plasma with optical emission spectrometry, ICP-OES (Inductive Coupled Plasma - Optical Emission Spectrometry). The concentrations of macroelements Ca, Mg, and Si in the analyzed samples were within the limits of the allowed values, while the multiplied concentration of Na was detected in samples U2, U3, U5 and U7. Elevated concentrations of microelements were recorded in the samples: U6 (As); U3-U5 (Se); U1 and U4 (Fe); U1-U4 and U7 (Mn), while the concentrations of other microelements (S, Ni, Cd) were in the allowed values according to the National legislation of water for human use.
