“…Total flavonoids (TF) were determined by the aluminium chloride method described by Hosu et al (2016) [23], with some adaptations. 0.5 mL of apple extract were treated with 0.4 mL of 25 g/L AlCl3 solution, 0.5 mL of 100 g/L sodium acetate solution and 4 mL distilled water.…”

Apple (Malus domestica Borkh.), a popular and widely cultivated fruit world-wide, contains bioactive compounds responsible for their health benefits. Here we report the amounts of some bioactive compounds: two major triterpenes (oleanolic and ursolic acids) and polyphenols (phenolic acids, flavan-3-ols, flavonoids and t-resveratrol), together with bioactive properties of twelve apple cultivars measured by chromatographic and spectrophotometric methods. Significant variations were found comparing the bioactive potential of the investigated cultivars. High contents of phenolic acids were identified in the Montuan, Golden Delicious and Cretesc cultivars, while the most flavonoid dominant was the Richard cultivar. Starkrimson, Jonatan, Beliy Naliv and Richard cultivars present higher antioxidant capacity. Oleanolic acid ranged from 11 to 83 mg/g apple extract, while ursolic acid ranged from 55 to 436 mg/g apple extract, with higher amounts in Richard and Montuan cultivars. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) allowed the discrimination of apple cultivars depending on polyphenolic and triterpene acids composition. Caffeic acid, gallic acid and epicatechin were identified as the main bioactive compounds in Starkrimson, Jonathan, Beliy Naliv and Richard cultivars, while ursolic and oleanolic acids were identified in high amounts in Richard, Montuan, Golden Delicious, Idared and Beliy Naliv apple cultivars. The results obtained in this study will contribute to the understanding of the bioactive composition of apples as well as the importance of their capitalization to obtain value-added products that promote human health.

“…The content of polyphenols was indicated a higher quantity of polyphenols in Muscat Ottonel wine (1310 mg GAE/L), followed by Feteasca Regala wine (810 mg GAE/L), values comparable with the total polyphenols content in some red wines [17,18], but lower than other red wines [19]. A lower quantity of polyphenols was found in Blasius wine, but comparable with some others Romanian white wines [20]. It is known that flavonoids are found in skin of grapes, are very healthier, but are causing a bitterness effect on wines [21].…”

Six white wines from Blaj vineyard obtained from clone and new created varieties of grapes, have been studied. Their volatile compounds, free amino acids, free fatty acids, content in polyphenols and flavonoid, antioxidant and antityrosinasic activity were compared. The results showed few differences among the analyzed wines. The volatile extracts of wines gave very similar compounds. The major compounds were phenylethyl alcohol. All the white wines of Blaj contained a large amounts of proline in comparison with the other amino acids and important essential amino acids. The fatty acids were found in very small quantities. Antioxidant activity and total content in polyphenols of wines showed that Muscat Ottonel have a very high antioxidant potential comparable with some red wines. The content in flavonoids is small in all white wines. Antityrosinasic activity of studied wine proved to be high to Blasius and Muscat Ottonel wine. The GC-MS method proved to be an excelent method for wine characterization.

“…In this regard, stable isotopes in combination with mineral composition and chemical markers were used for investigation of the geographical origin of tomatoes (Mahne Opatic ´et al 2018). Stable isotopes or elemental composition, either independently or in combination were also used for discrimination of other agroproducts with respect to their geographical origins such as: hot pepper (Marincas et al 2018), potato (Magdas et al 2017), wine (Hosu et al 2016), or to differentiate the agriculture type (organic vs. conventional vegetables as well as greenhouses vs. field) (Cristea et al 2017;Magdas et al 2018). Most commercial tomatoes, especially in northern European countries, are produced in greenhouses that allow better control of agronomic and environmental factors.…”

In this study, 41 tomato samples were investigated by means of stable isotope ratios (d 13 C, d 18 O and d 2 H), elemental content, phenolic compounds and pesticides in order to classify them, according to growing conditions and geographical origin. Using investigated parameters, stepwise linear discriminant analysis was applied and the differences that occurred between tomato samples grown in greenhouses compared to those grown on field, and also between Romanian and abroad purchased samples were pointed out. It was shown that Ti, Ga, Te, d 2 H and d 13 C content were able to differentiate Romanian tomato samples from foreign samples, whereas Al, Sc, Se, Dy, Pb, d 18 O, 4,4 0 -DDT could be used as markers for growing regime (open field vs. greenhouse). For the discrimination of different tomato varieties (six cherry samples and fourteen common sorts) grown in greenhouse, phenolic compounds of 20 samples were determined. In this regard, dihydroquercetin, caffeic acid, chlorogenic acid, rutin, rosmarinic acid, quercetin and naringin were the major phenolic compounds detected in our samples. The phenolic profile showed significant differences between cherry tomato and common tomato. The contents of the chlorogenic acid and rutin were significantly higher in the cherry samples (90.27-243.00 lg/g DW and 160.60-433.99 lg/g DW respectively) as compared to common tomatoes (21.30-88.72 lg/g DW and 24.84-110.99 lg/g DW respectively). The identification of dihydroquercetin is of particular interest, as it had not been reported previously in tomato fruit.
