How wine blending influences their biological activity: A case study of Cabernet Sauvignon and Merlot coupages.

Blending different grape varieties or wines is essential in winemaking to enhance sensory attributes, but could potentially impact the biological activity of the final product. This study investigates the polyphenolic profile and bioactivities of monovarietal wines Cabernet Sauvignon (CS) and Merlot (M), their blends in three different ratios (CS1M1, CS3M1, CS1M3), as well as one commercial coupage (CSM). Enzyme inhibition (α-amylase, α-glucosidase, lipase, tyrosinase), antioxidant properties (inhibition of AAPH-induced ROS generation in U937 cells and lipid peroxidation), and anti-inflammatory properties (inhibition of PGE production in U937 cells) were assessed.

Polyphenolic profile and in vitro biological activity of Serbian orange (skin fermented white) wines.

Orange wines are made from white grapes, but with prolonged skin contact during fermentation. Available data on their composition and potential health benefits are limited, so polyphenolic profile (HPLC analysis) and in vitro biological activities (enzyme inhibition, antioxidant, and anti-inflammatory) of 24 Serbian orange wines were analyzed, including the correlation between determined composition and bioactivities. The wines displayed distinct polyphenolic profiles, enabling partial differentiation based on overall polyphenol content, including dominant components (catechin, gallic and caffeic acids), along with occasional occurrences of anthocyanins.

Elemental Profile and Health Risk of Fruška Gora Wines.

The elemental composition of wine is influenced by endogenous sources and interventions from winemakers. The ICP-MS analysis of Fruška Gora wines (113) from vintages spanning across a decade (2011-2020), produced by 30 wineries and representing 18 autochthonous and international wine varieties, allowed a comprehensive insight into their elemental composition. Based on the mean concentrations of 23 investigated elements, B, Fe, and Mn, which were determined in mg per L of wine regardless of its colour or origin, were the most abundant.

Could elderberry fruits processed by modern and conventional drying and extraction technology be considered a valuable source of health-promoting compounds?

The influence of drying and extraction processes on the phytochemical composition and biopotential of elderberry is challenging for the food industry. For this reason in this research two drying techniques (lyophilization and natural convection) and three extraction techniques (ultrasound (UAE), microwave (MAE), and conventional (maceration (MAC)) was applied using two"green" solvents (water and 50 % ethanol). Results of the research showed that lyophilization was a better way of drying than natural convection, while MAE extraction was the most efficient technique for the isolation of secondary metabolites.

Plantain (Plantago L.) species as modulators of prostaglandin E and thromboxane A production in inflammation.

Ethnopharmacological Relevance: Worldwide distributed plantains (genus Plantago L.) are extensively used in the traditional, but some of them are also accepted in the modern medicine. Wide range of usages is mainly connected to the inflammation processes.

Activity profiling of Serbian and some other European Merlot wines in inflammation and oxidation processes.

Merlot are worldwide recognized red wines. Several studies show that red wines have health benefits, mainly due to their phenolic constituents. This study evaluates twelve Serbian and other five European (French, Italian, Macedonian, Slovenian, Spanish) Merlot wines in respect of their phenolic composition and biological activity.

The Effects of Trifluoromethylated Derivatives on Prostaglandin E2 and Thromboxane A2 Production in Human Leukemic U937 Macrophages.

Background: A convenient approach to modulation of the inflammation has an influence on the production of inflammatory mediators - icosanoids, generated in arachidonic acid (AA) metabolism. The common therapeutic activity of non-steroidal anti-inflammatory drugs (NSAID), such as aspirin, includes inhibition of two crucial enzymes of AA metabolism - cyclooxygenase- 1 and -2 (COX-1/2), with certain risk for gastrointestinal and renal intolerance. Ever since the enrolment of COX-2, particularly overabundance of its main products prostaglandin E2 (PGE2) and thromboxane A2 (TXA2) in numerous pathological processes was recognized, it became a significant therapeutic target.
