Abstract: DOI: 10.24193/subbchem.2022.2.07 Published Online: 2022-06-30 Published Print: 2022-06-30 pp. 113-129 VIEW PDF FULL PDF Tomato is one of the most consumed foodstuffs around the world and major dietary source of lycopene. The main objectives of this study were evaluation of antioxidant activity, using DPPH, ABTS, FRAP, TRP and CUPRAC assays, as well as total phenolic, total flavonoid, lycopene and β-carotene content in 30 tomato and cherry tomato cultivars commonly consumed in Serbia. Tomato with the highest total phenol and total flavonoid content was tomato Indigo Rose (17.56 mg GAE g-1 DW and 30.30 mg RE g-1 DW, respectively), which showed excellent antioxidant characteristics. Total lycopene content was lower in yellow tomato species compared to the red ones, and the highest lycopene content was 0.283 mg g-1 DW for tomato Red Big Pearl. Cluster analysis yields dendrogram, separating tomato and cherry tomato cultivars into three statistically significant clusters ((Dlink / Dmax)×100 < 50). Keywords: Tomato, Antioxidant characteristics, Bioactive compounds, PCA, Cluster analysis |
