The bioactive compounds, as well as the in vitro antioxidant activity of two Savoy cabbage cultivars, Dama and Leticia, grown in west of Spain under similar conditions were identified, quantified and compared. We found that cv. Dama presented in general betters results when compared with cv. Leticia. Cv. Dama presented higher concentrations of chlorophyll a (2.26 mg/100 g fresh weight), total phenolic content (102.71 mg of chlorogenic acid equivalent/100 g fresh weight) and total intact glucosinolates (195.22 µmol of sinigrin equivalent/100 g fresh weight). Thus, cv. Dama exhibited higher values of in vitro antioxidant activity.

ABSTRACT The family farming from the Borborema Territory-PB, Brazil, produces sweet oranges that supply the regional market. In this context, it is necessary to define standards of identity and quality, as well as to quantify the bioactive compounds in the fruit, in view of adding value and creating more competitive markets. This work sought to evaluate the quality, bioactive compounds and total antioxidant activity (TAA) of oranges from family farming. A 3x3 factorial completely randomized design was used, with three cultivars (Baía, Comum, Mimo-do-Céu) and three maturity stages (predominantly green, green/yellow, yellow), with 60 replications of 1 fruit for the physical evaluations, and 4 of 15 fruit for the others. The whole fruits were evaluated by color index, length, diameter, fresh weight and firmness. The juice was assessed for yield, pH, soluble solids (SS), titratable acidity (TA), SS/AT ratio, and ascorbic acid. Total extractable polyphenols (TEP) and ABTS•+ and DPPH• total antioxidant activity (TAA) were measured in the juice and albedo. The 'Baía' and 'Mimo-do-Céu' oranges presented quality parameters aligned with the CEAGESP standards. On average, the ascorbic acid content was higher than 45 mg 100 g-1, with ‘Mimo-do-Céu’ presenting the highest content (50.26 mg 100 g-1). During maturation, the firmness decreased, and the SS, TEP and TAA of the juice and the albedo increased. In general, the TEP content was about eight-fold higher in the albedo than juice, corresponding to the much higher TAA in this portion, thereby highlighting its higher functional potential, especially for ‘Baía’ orange.

The effect of melatonin pomegranate tree treatments on fruit quality and bioactive compounds with antioxidant activity at harvest and during storage at 10 °C for 60 days was assayed in two consecutive years, 2019 and 2020. In the first year, trees were treated with 0.1, 0.3 and 0.5 mM of melatonin along the developmental fruit growth cycle, and results showed that bioactive compounds (total phenolics and total and individual anthocyanins) and antioxidant activity at harvest were higher in fruits from melatonin-treated trees than in controls. Other fruit quality parameters, such as firmness, total soluble solids and aril red colour, were also increased as a consequence of melatonin treatment. In fruit from control tress, firmness and acidity levels decreased during storage, while increases occurred on total soluble solids, leading to fruit quality reductions. These changes were delayed, and even maintenance of total acidity was observed, in fruit from melatonin-treated trees with respect to controls, resulting in a fruit shelf-life increase. Moreover, concentration of phenolics and anthocyanins and antioxidant activity were maintained at higher levels in treated than in control fruits during the whole storage period. In general, all the mentioned effects were found at the highest level with the 0.1 mM melatonin dose, and then it was selected for repeating the experiment in the second year and results of the first year were confirmed. Thus, 0.1 mM melatonin treatment could be a useful tool to enhance aril content on bioactive compounds with antioxidant activity and health beneficial effects and to improve quality traits of pomegranate fruit, at harvest and during postharvest storage.

The article presents the results of biochemical studies of the total antioxidant activity of the hepatoprotective collection of plant origin and its individual components, which show that it consists of birch leaves (Betulae folia), tansy flowers (Tanaceti flores), phytohepatol No. 2 (choleretic collection No. 2) and individual its components have pronounced antioxidant activity. More antioxidant activity founded in tansy and true hepatoprotective collection. Comparative tests of the flowers of meadowsweet, with the highest antioxidant activity, showed the promise of their use in the collections of medicinal plants as effective natural metabolic regulators. The total antioxidant activity of the water extract collection at 13.56% rel. exceeded the calculated value obtained by summing the activities of the individual components of the collection, which indicates the presence of synergism in their action, which may be of value for use in the treatment and prevention of liver diseases. When all components of the drug collection are finished, the indicator increases by 11-24 % rel., which indicates the thermal stability of the antioxidant substances that make up their composition. In the oxidation of aqueous extracts of the components of hepatoprotective collection with hydrogen peroxide, the most stable were antioxidants of birch leaves. It was found that collection only at a ratio of 7.7 g per liter of water shows synergism (15 % rel.), and the rest of all the samples we tested are antagonistic. The detected increase in the antioxidant activity of the new collection compared with the effects of its individual components allows us to consider it as a promising dosage form for use in the treatment and prevention of liver diseases.
