Aloe Vera leaves have great potential as an economic supplement with an adequate nutritional profile. The current study aimed to fortify plain (loaf) cakes with Aloe Vera leaf gel (AVG) powder. AVG was freeze-dried to produce Aloe Vera powder (ALP), and four plain (loaf) cakes were prepared with different proportions of ALP (0, 4, 6, and 8%). ALP contained significantly (p < 0.05) more protein (22.23 vs. 12.24), ash (19.83 vs. 0.64), and iron (175 vs. 3.05) than refined wheat flour (RWF). Along with total polyphenols and total flavonoids, ALP demonstrated good antioxidant activity. ALP-cakes and RWF-cakes were also evaluated for their nutritional and functional properties. The addition of 6 and 8% ALP to the formulation increased total polyphenols, total flavonoids, and antioxidant activity in plain (loaf) cakes. Hardness and chewiness increased in ALP-cakes but decreased in RWF-cakes, while cohesiveness and springiness decreased in ALP-cakes. In conclusion, the best formulation was a 4% ALP incorporated cake, and ALP can be supplemented in plain cakes at a rate of up to 8% to improve nutrient value. This is the first study to evaluate the quality characteristics of fortified plain (loaf) cakes using ALP.

Flavonoids have important biological activities, such as anti-inflammatory, antibacterial, antioxidant and whitening, which is a potential functional food raw material. However, the biological activity of Fengdan peony flavonoid is not particularly clear. Therefore, in this study, the peony flavonoid was extracted from Fengdan peony seed meal, and the antioxidant, antibacterial and whitening activities of the peony flavonoid were explored. The optimal extraction conditions were methanol concentration of 90%, solid-to-liquid ratio of 1:35 g:mL, temperature of 55 °C and time of 80 min; under these conditions, the yield of Fengdan peony flavonoid could reach 1.205 ± 0.019% (the ratio of the dry mass of rutin to the dry mass of peony seed meal). The clearance of Fengdan peony total flavonoids to 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical, hydroxyl radical and 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) free radical could reach 75%, 70% and 97%, respectively. Fengdan peony flavonoid could inhibit the growth of the Gram-positive bacteria. The minimal inhibitory concentrations (MICs) of Fengdan peony flavonoid on S. aureus, B. anthracis, B. subtilis and C. perfringens were 0.0293 mg/mL, 0.1172 mg/mL, 0.2344 mg/mL and 7.500 mg/mL, respectively. The inhibition rate of Fengdan peony flavonoid on tyrosinase was 8.53–81.08%. This study intensely illustrated that the antioxidant, whitening and antibacterial activity of Fengdan peony total flavonoids were significant. Fengdan peony total flavonoids have a great possibility of being used as functional food materials.

Flavonoids, a major constituent ofCotinus coggygria(CC), have been reported to possess diverse biological activities, including antigenotoxic and hepatoprotective effects; however, few studies have investigated the biological activity of the total flavonoids ofCotinus coggygria, especially in terms of its cytotoxicity in cancer cells. In the present study, theCotinus coggygriaflavonoids (CCF) were extracted fromCotinus coggygriaand characterized by HPLC. These results indicated that CCF extracts could inhibit cell proliferation, with IC50values of 128.49 µg/mL (U87), 107.62 µg/mL (U251), and 93.57 µg/mL (DBTRG-05MG). The current investigation also revealed that CCF induced apoptosis in highly malignant glioblastoma cells, a process that apparently involved the inhibition of Akt coupled with ERK protein expression. This finding suggests that the PI3K/Akt-ERK signaling pathway is regulated by CCF and leads to the inhibition of the glioblastoma cancer cells. Furthermore, a significant antitumor effect of CCF was observed in xenograft animal models of glioblastoma multiformein vivo. Taken together, these data suggest that CCF is the active component in theCotinus coggygriaplant that offers potential therapeutic modality in the abrogation of cancer cell proliferation, including the induction of apoptosis.

Propolis is a resinous material rich in flavonoids and involved in several biological activities such as antimicrobial, fungicide, and antiparasitic functions. Conventionally, ethanolic solutions are used to obtain propolis phytochemicals, which restrict their use in some cultures. Given this, we developed an alcohol-free high-performance extractive approach to recover antibacterial and antioxidants phytochemicals from red propolis. Thus, aqueous-solutions of ionic liquids (IL) and eutectic solvents were used and then tested for their total flavonoids, antioxidant, and antimicrobial activities. The surface-responsive technique was applied regarding some variables, namely, the time of extraction, the number of extractions, and cavitation power (W), to optimize the process (in terms of higher yields of flavonoids and better antioxidant activity). After that, four extractions with the same biomass (repetitions) using 1-hexyl-3-methylimidazolium chloride [C6mim]Cl, under the operational conditions fixed at 3.3 min and 300 W, were able to recover 394.39 ± 36.30 mg RuE. g−1 of total flavonoids, with total antioxidant capacity evaluated up to 7595.77 ± 5.48 μmol TE. g−1dried biomass, besides inhibiting the growth of Staphylococcus aureus and Salmonella enteritidis bacteria (inhibition halo of 23.0 ± 1.0 and 15.7 ± 2.1, respectively). Aiming at the development of new technologies, the antimicrobial effect also presented by [C6mim]Cl may be appealing, and future studies are required to understand possible synergistic actions with propolis phytochemicals. Thereby, we successfully applied a completely alcohol-free method to obtain antimicrobials phytochemicals and highly antioxidants from red propolis, representing an optimized process to replace the conventional extracts produced until now.

The antioxidant properties of cool-climate Regent wines from Podkarpacie region, Poland were investigated. Total polyphenols, total flavonoids, total monomeric anthocyanins, trans-resveratrol concentration, radical scavenging ability using 1,1-diphenyl-2-picryl-hydrazyl (DPPH) and total antioxidant capacity with TEAC and FRAP methods were measured. The average contents of the compounds determined for Regent wines were comparable to the respective data available in literature found for warm-climate wines. Correspondence Analysis of the data revealed the relation of total polyphenols content and antioxidant capacity and radical scavenging ability of studied wines, and in lesser extent correlation with total flavonoids content. The total monomeric anthocyanins content and resveratrol concentration were poorly related to the total polyphenols content and antioxidant capacity.

AbstractA. hypochondriacus leaves contained ample phytopigments including betalain, anthocyanin, β-xanthin, β-cyanin, and bioactive phytochemicals of interest in the industry of food. We have been evaluating the possibility of utilizing phytopigments of amaranth and bioactive constituents for making drinks. Therefore, we evaluated bioactive phytopigments and compounds including the potentiality of antioxidants in A. hypochondriacus leaves. A. hypochondriacus leaves have abundant protein, carbohydrates, and dietary fiber. We found considerable levels of inorganic minerals including magnesium, calcium, potassium (3.88, 3.01, 8.56 mg g−1), zinc, manganese, copper, iron (16.23, 15.51, 2.26, 20.57 µg g−1), chlorophyll b, chlorophyll ab chlorophyll a (271.08, 905.21, 636.87 μg g−1), scavenging capacity of radicals (DPPH, ABTS+) (33.46, 62.92 TEAC μg g−1 DW), total polyphenols (29.34 GAE μg g−1 FW), β-xanthin, betalain, β-cyanin (584.71, 1,121.93, 537.21 ng g−1), total flavonoids (170.97 RE μg g−1 DW), vitamin C, β-carotene, carotenoids (184.77, 82.34, 105.08 mg 100 g−1) in A. hypochondriacus leaves. The genotypes AHC6, AHC4, AHC11, AHC5, and AHC10 had a good scavenging capacity of radicals. Polyphenols, phytopigments, flavonoids, and β-carotene of A. hypochondriacus had potential antioxidant activity. Extracted juice of A. hypochondriacus can be an ample source of phytopigments and compounds for detoxification of reactive oxygen species (ROS) and attaining nutritional and antioxidant sufficiency.

Beetroot is a widely consumed crop all over the world and contains plenty of bioactive compounds. In this study, we analyzed the bioactive as well as the antimicrobial properties of the oven-dried beetroot (pulp and peel) using different solvents. The 50% methanolic extract yielded the highest content of total polyphenols and total flavonoids as well as the reducing power of the beetroot. The beetroot peel exhibited a higher content of total polyphenols, total flavonoids, and reducing power activity under all the extraction solvents. Mixture of methanol and water (50% v/v) extracted the highest chlorogenic acid (78.24 mg/100 g) of the dried beetroot peel, while 1,2-dihydroxybenzene was the most noteworthy phenolic compound (42.52 mg/100 g) in beetroot peel methanolic extract. The 50% methanolic extract of both peel and pulp demonstrated the highest antibacterial and anticandidal potential. These results can be helpful for beetroot consumption.

The article is dealing with evaluation of four fruit maturity stages of 6 selected clones (LKL-3, LKL-14, LKL-19, LKL-33, LKL-96 and LKL-103) of Lonicera kamtschatica (Sevast.) Pojark in relation to total polyphenols, flavonoids content and antioxidant activity of berries. The experiment in 5 replications of each clones has been established in the conditions of Botanical Garden in Nitra (Slovak republic)in 2016. The results of analyses proved that in respect of the total polyphenols content (TPC), the content of flavonoids (FC) and the antioxidant activity the most valuable clones at the stage of full ripened fruit were following: LKL-14 (8.77; 2.57 g/kg FW; 9.07 g/kg), LKL-33 (6.77; 2.84 g/kg FW; 9.16 g/kg) and LKL -3 (8.19; 2.61 g/kg FW; 8.94 g/kg). The results of statistical analyses by one-way analysis of variance proved significant differences among assayed clones in total flavonoids and antioxidant activity of fruit but no differences among content of total polyphenols and assayed stages of fruit maturity.
