“…Anthocyanins are natural plant pigments that belong to the family of polyphenolic compounds classified under flavonoids. Plant raw materials containing anthocyanins are often red, pink, blue, or black in color [41,42]. Anthocyanins are also bioactive compounds that are beneficial to humans [31].…”

Apple juice is rich in phenolic compounds that are important as natural antioxidants. In turn, blue honeysuckle berry juice is a valuable source of bioactive ingredients and can be an interesting and beneficial supplement to fruit juices. The aim of this study was to examine the physicochemical and sensory properties of the newly designed mixture of apple juice and blue honeysuckle berry juice. The addition of blue honeysuckle berry juice to apple juice had a significant effect on the content of anthocyanin and vitamin C in the newly designed fruit juices. After production, the content of anthocyanins and polyphenols in the blue honeysuckle berry juice was high (595.39 and 767.88 mg/100 mL, respectively). As the concentration of blue honeysuckle berry juice added to apple juice was increased, the polyphenol content also increased. The juices analyzed after 4 months of storage were lighter and showed a less intense red color than the juices analyzed directly after production. Antioxidant activity (ABTS assay) in the apple juice mixed with 10% blueberry juice was almost 3 times higher than the pure apple juice after 3 months of storage; the addition of 30% blueberry juice significantly increased the antioxidant activity of the apple juice. Thus, the results of this research have expanded the existing knowledge about the health and sensory properties of apple juice mixed with blue honeysuckle berry juice. These findings can be utilized in further research aiming at the development of new products that can meet consumer expectations.

“…The flavylium compounds consist of anthocyanin pigments (callistephin, chrysanthemin, oenin, mytrillin) and anthocyanidin pigments (peonidin, petunidin) were investigated to identify their potential of application as the photosensitizer in the solar cell. [20] According to the obtained results, the peonidin dye is the preferred photosensitizer for DSSC because of good short-circuit current density, more ability to harvest light, the lower energy barrier for the electron injection, and favorable optic characteristics. [20] Generally, natural dyes including chlorophyll, carotenoid, flavonoid, and anthocyanin are a relatively easy extract from the natural products in comparison whit the synthetic dyes.…”

“…[17] The influences of the chemical structure of the sensitizers on the photovoltaic properties were investigated. [17][18][19][20] For example, polypyridyl dyes based on Cr 2+ and V 3+ show better performance in comparison with ruthenium-and other scarce metal-based polypyridyl dyes due to the moderate LHE , high efficiencies of electron and hole injection, which make them promising alternatives to scarce Ru 2+ metal ion. [18] Also, theoretical insights into the effect of polycyclic aromatic hydrocarbons (PAHs) on monascus pigments (MPs) and as a photosensitizer for solar cells showed that the presentence of the PAHs reduces the electronic band gap and the electron injection efficiency of MPS.…”

Photovoltaic properties of the natural dyes of chlorophylls consist of Chl a, Chl b, Chl c2, Chl d, Phe a, Phe y and Mg-Phe a, were studied in the gas phases. The extension of the π-conjugated system, the substitution of the central Mg2+ and proper functional groups in the chlorophyll structures can amplify the charge transfer and photovoltaic performance. Chl a shows more favorable dynamics of charge transfer than other studied chlorophylls. Chl d, Phe a, Phe y and Mg-Phe a, have a greater rate of the exciton dissociation in comparison with Chl a, Chl b, and Chl c2 originated from a lower electronic chemical hardness, a lower exciton binding energy, and a bigger electron-hole radius. As a result, better efficiencies of the light-harvesting and energy conversion of the chlorophylls mainly appear in the Soret band. Finally, based on the energy conversion efficiency, Chl a, Phe a, and Mg-Phe a, are proposed as the best candidates for using in the dye-sensitized solar cells.

“…The following paragraphs presents the main biological properties of different Fragaria species, as emerging from the literature data published in the past decade. Particularly, the anthocyanins family represent the subject of several review papers published in the last years, dealing with their bioavailability and potential health benefits [63][64][65]. The following chapters includes only the studies regarding the biological activity of compounds or extracts obtained from Fragaria species (not studies presenting the activity of compounds that are found in those plants).…”

The strawberries represent in our days one of the main fresh fruits consumed globally, inevitably leading to large amounts of by-products and wastes. Usually appreciated because of their specific flavor, the strawberries also possess biological properties, including antioxidant, antimicrobial, or anti-inflammatory effects. In spite of the wide spread of the Fragaria genus, few species represent the subject of the last decade scientific research. The main components identified in the Fragaria species are presented, as well as several biological properties, as emerging from the scientific papers published in the last decade.
