“…[12] Beside catechin and epicatechin, proanthocyanidin dimers represent major constituents of grape seed extracts putting them in the focus of contemporary studies since it was shown that only monomers and dimers are absorbed into human intestinal tissue and circulation in significant amounts. [14] Regarding the quantity of epicatechin which was found to be almost ten times less than the amount of catechin, [16] in our study that difference was not so pronounced. On the contrary, in the most of our samples the ratio was approximately 1:1, similar to the results of Godjevac et al, [12] while in samples 40/8, 41/1, 41/3, 41/4, 42/4, 43/2, 43/3, 43/5, 43/7, and 43/8 epicatechin was present in approximately two times higher amount compared to the catechin content.…”

“…Despite shown differences in Prokupac phenolic profiles, compared to some other well-known red and white vine varieties such as Cabernet Sauvignon, Merlot, Shiraz or Sauvignon Blanc, Chardonnay, and Riesling, Prokupac seeds could be considered as the notable source of phenolic compounds. [16] In our study, the highest content of phenolic compounds was determined in Prokupac clone 43/1, followed by clones 40/1 and 40/2. Multivariate data analysis of polyphenolic content was applied to understand the overall variability within the samples of 25 clones.…”

“…Pantelić et al investigated phenolic composition of different parts of grape berries of 13 vine varieties grown in Serbia and also found that flavan-3-ols were the dominant compounds in tested grape seeds. [16] According to their results for Prokupac variety, the compound present in the highest amount was also catechin (1111.66 mg/kg) followed by gallocatechin gallate (788.80 mg/kg). Furthermore, Pantelić et al have detected gallocatechin gallate, epigallocatechin, catechin 3-gallate, epigallocatechin gallate, gentisic acid, and hydroxycinnamic acids, while proanthocyanidin dimers and trimers were not detected.…”

“…Namely, they used 80 % MeOH contained 0.1 % HCl for the extraction of ground grape seeds. [16] In our study, we followed extraction procedure described by Gođevac et al, using aqueous methanol system free of acids for the extraction of intact grape seeds. These conditions were applied since interflavan linkages within proanthocyanidin oligomers showed acidic lability, and sensitivity of polyphenols toward oxidation.…”

Grape pomace (grape skin, seeds, and stems) represents a valuable source of bioactive compounds, thus the interest in making use of these wine waste products is increasing. Prokupac is an autochthonous Serbian variety of black grape with a long tradition in production of red wine. Identification of the superficial polyphenolic compounds by LC/MS revealed presence of 19 compounds including hydroxybenzoic acid derivatives, ellagic acid derivatives, flavan‐3‐ol monomers, proanthocyanidins, and flavonols. Catechin and epicatechin together with proanthocyanidins were the most abundant compounds and the highest content of phenolic compounds was determined in Prokupac clones 43/1, 40/1, and 40/2. Grape seed oil consisted of dominantly UFA (87–95 %) where methyl linoleate was the most abundant in all samples (69–81 %). Palmitic (3–8 %) and stearic acid (2–4 %) methyl esters were dominant SFA. Prokupac clone 43/3 was the most abundant in UFA (95 %) with the lowest percentage of SFA (5 %), while clones 41/1 and 43/5 had the lowest percentage of UFA (87 %) and the highest content of SFA (13 %). Favorable chemical profile of Prokupac clone seeds implicates its potential to be used as a raw material in further processing and possibility to be included as one of the quality parameters in further selection of the most interesting Prokupac clone.

The influence of leaf area and various variants of manual defoliation on the phenolic profile of the Prokupac variety grape berry were investigated in the agroecological conditions of southern Serbia. The following four trial variants of manual defoliation were assessed: Early defoliation-variant I (flowering stage, 50% open flowers); early defoliation-variant II (grape size 3-5 mm); late defoliation-variant III (onset of grape ripening, veraison); and control (no defoliation). The first six leaves of each primary shoot were removed from all defoliated vines. The greatest assimilation area of primary and lateral shoots during the study was observed in the control, i.e., the trial variant with no defoliation. Defoliation significantly decreased the grape yield of the all three defoliated variants in regard to the control. The phenolic profile of the three variants and control was established by analyzing the grape seeds and skin. Based on the collected results for the Prokupac variety, significant differences between the trial variants were established regarding the content of phenols and total polyphenols, as well as radical scavenging activity. Defoliation variants showed a significant effect on the total phenols content of grape skin. In all defoliation variants, as well as in the control, high amounts of ellagic acid were measured. Resveratrol was identified only in grape skin samples of the control variant. The removal of leaves increased the concentration of phenolic compounds in variants where early defoliation was applied. The highest total anthocyanins content was found in 2015 in variant I, where leaves were removed during the full flowering stage.

In this study, we have analyzed the anthocyanin composition of skin extracts of three red grape varieties Prokupac, Evita and Čokot Zemun in order to distinguish these cultivars based on their anthocyanin profile. Also, mechanical analysis of grape bunches and berries was performed. According to our results, seventeen anthocyanins were identified using LC/MS technique and quantitative differences were recorded using HPLC‐DAD method. The highest content of total anthocyanins was obtained for Evita variety and the lowest one was recorded in Prokupac. Also, clear differences were observed in anthocyanins ratios. In comparison to Prokupac and Evita varieties, Čokot Zemun was characterized with a high content of coumaroyl derivatives of anthocyanin compounds, while high levels of acetylated derivatives were recorded in Prokupac. Data reported in this study represent a certain contribution to a database of mechanical properties and chemical composition of grape varieties originating from Balkan.
