Free radicals have an important role in food and in chemical material degradation, contributing to the occurrence of many human health problems, but the antioxidants can considerably delay or prevent the oxidation of easily oxidable substrates. The present research aimed to assess the antioxidant activity, expressed by the presence of polyphenols, flavonols, flavones, anthocyanidins and flavanols, in several Romanian and Cypriot wines. The wine phenolics content was analysed by highperformance liquid chromatograph (HPLC) Shimadzu equipped with two chromatographic columns. Higher concentrations were registered in all red wines. The antioxidant activity quantification was carried out by the DPPH method, a simple and cheap approach based on the absorbance decrease determination of the DPPH radical (2,2-diphenyl-1-picrylhydrazyl) in the presence of antioxidants. The highest antioxidant activity for white wines was determined at 'Spouriko' for Cypriot wine from 2013 (EC 50 = 1/38) while for Romanian wines, the highest value was found in a 'Tămâioasă românească' (EC50 = 1/58) and for red wines at 'Maratheftiko' wine from 2012 (EC50 = 1/680) and in 'Fetească Neagră' wine from 2014 (EC50 =1/590). This study provides relevant information to consumers and industry alike regarding the beneficial role wine plays for human health. It also can act as a baseline for choosing a certain product, according to its sanogenic potential.

“…Grapes and wine contain high number of phenolic compounds. Phenolic compounds of wine can be classified in flavonoids and nonflavonoids (Belajova 2012;Cotea et al 2012). Nonflavonoids include phenolic acids, cinnamic acids, stilbenes, phenolic alcohols and aldehydes.…”

The aims were to determine the polyphenolic profile of red wines from Spanish Designation of Origin (DO) Rías Baixas and Ribeira Sacra and to evaluate the feasibility of using polyphenolic profiles and chemometric tools to classify wines for authentication purposes. Trans-resveratrol, oenin, malvin, (+)-catechin, (−)-epicatechin, quercetin and syringic acid were determined in 39 samples. Soft independent modeling of class analogy (SIMCA), linear discriminant analysis (LDA) and support vector machine classification (SVM) were used to classify. For resveratrol, Ribeira Sacra red wines showed higher values than Rías Baixas wines (4.60 and 3.36 mg L −1 , respectively). SVM classification was adequate for 100 % classification of wines by their polyphenolic profile. SIMCA classification was also adequate for wine classification of DO Rías Baixas and Ribeira Sacra wines. As conclusion, polyphenolic profile can be used for classification of DOs. The models can discriminate outside wines. Thus, this approach can be useful for authentication purposes.

“…All these features make these materials attractive adsorbents. Thus, mesoporous matrices have been already proven to be efficient supports for adsorption of various bioactive compounds such as anthocyanins [2], flavonoids [3], polyphenols [4,5], plant hormones [6], carotenoids [7], alkaloids [8], vitamins [9], antimicrobial agents [10], glycopeptides [11], natural flavoring agents [12] and drugs [13][14][15]. Among the various classes of mesoporous matrices, SBA-15 (Santa Barbara Amorphous) and MCF (mesocellular foam) silicas are considered promising candidates for application in adsorption.…”
