Antioxidant activity, lipid oxidation, fatty acid composition and volatile compounds of duck eggs supplemented with clove extract were monitored over the salting period. The results indicated that application of clove extracts significantly reduced 2-thiobarbituric acid reactive substances and anisidine values as well as the conjugated dienes levels during curing. Clove extracts along with salting time had significant effects on the fatty acid composition. The predominant fatty acid in salted duck eggs supplemented with clove extracts for 14 day of the salting process was oleic acid, followed by palmitic acid and arachidonic acid. Additionally, treated eggs exhibited a higher docosahexaenoic acid content than that of control. The results of SPME GC-MS showed the presence of 46 and 37 volatiles in the treated eggs. Eugenol, as the primary bioactive component of clove, was detected in salted eggs supplemented with clove extracts. In addition, analyzing the results obtained through electronic nose showed that clove extract brought significant changes in salted eggs flavor components.

“…In nutraceuticals, the extracts of Fallopia japonica are used as a source of resveratrol. It has been shown that resveratrol exhibits the estrogenic [30], antioxidant [31], antiviral [32], antiplatelet [33], anti-thyroid [34] and cancer chemopreventive activity [35]. Furthermore, resveratrol enhances the expression and activity of endothelial nitric oxide synthase [36] and induces vasorelaxation [37].…”

Phytoestrogens represent polyphenolic and non-steroid compounds that have a similar structure and biological activity as human estrogens. They are the plant secondary metabolites and widespread in over 300 various plant species. The phytoestrogens are divided into two main subgroups, isoflavonoids and lignans. The isoflavonoids are divided into isoflavones and coumestans. Isoflavones are most present in soybean and red clover. A great number of isoflavones has been identified in the plants in the form of non-active glycosides (daidzein and genistein) and in the form of 4'-methylated derivatives (formononetin and biochanin A). Coumestans can also be found in red clover and legumes, while lignans are most present in the flax seed. Coumestans have the most pronounced estrogenic effect of all phytoestrogens. The most famous representative of this subgroup of compounds is coumestrol. Lignans include matairesinol, secoisolariciresinol, lariciresinol, pinoresinol and their metabolites, enterodiol, enterolactone and equol. Numerous studies in animals and humans have shown that phytoestrogens can have protective effects in the estrogen-dependent conditions and estrogen-dependent diseases. It was also shown that the use of phytoestrogens can have a positive effect on insomnia and cognitive functions, i.e. neural disorders, such as Alzheimer's disease. They can express the antioxidant activity in two ways, as the scavengers of free radicals or by the formation of chelating complexes with metal ions. Free metal ions increase the amount of reactive oxygen species by reduction of hydrogen peroxide resulting in a very reactive hydroxyl radical.

The aim of this paper was to prepare the solid-state inclusion complexes of trans-resveratrol with β-cyclodextrin and (2-hydroxypropyl)-β-cyclodextrin from ethanol-water mediums in order to improve its physico-chemical properties. The structure characterization was performed using FTIR, XRD and NMR methods. It was confirmed that the complexed trans-resveratrol has higher photostability than free trans-resveratrol. The results of DPPH assay suggested that the complexes have enhanced the antioxidant activity compared with trans-resveratrol. The inclusion complex with (2-hydroxypropyl)-β-cyclodextrin showed a better antioxidant activity than the complex based on β-cyclodextrin. The prepared inclusion complexes represent potential pharmaceutical active substances for a new products design.
