“…The elderberry fruit, analyzed in this study, had an equal or higher antioxidant capacity as compared with flowers of the same cultivars or wild plants from the same locations (Figure 1.). This stands in contrast to earlier studies by Dawidowicz et al (2006) [20] and Kołodziej et al (2011) [21] who used the DPPH (2,2-diphenyl-1-picrylhydrazyl) and FRAP (Ferric Reducing Antioxidant Power) methods for their measurements and found higher radical scavenging activity in elderberry flowers. In addition, fruit and flowers of the analyzed cultivars demonstrated significantly higher antioxidant activity that those harvested from wild growing plants (Table 3).…”

“…The correlation coefficient was 0.93 for fruit and 0.97 for flowers (Table 4). Kołodziej et al (2011) showed that elderberry flowers contained more phenolic compounds than elderberry fruit collected from the same locations. A similar observation was made for infusions from dried elderberry flowers and dried elderberry fruit; flowers were always found to be richer in various phenolic compounds, especially flavonoids, than in the fruit [21,27].…”

This study compared the mineral content and bioactive properties of flowers and fruit coming from wild elderberry plants with those of flowers and fruit harvested from elderberry cultivars grown in an orchard. Elderberry fruit and flowers were analyzed for the content of selected minerals, phenolic compounds, and anthocyanins, as well as for antioxidant activity. Mineral content was determined by the atomic absorption spectrometry method, while antioxidant activity and the content of polyphenols and anthocyanins were determined by spectrophotometric methods. Flowers were found to contain more total ash and much higher content of most of minerals, except magnesium which was present in high concentrations in fruit. Fruit showed significantly higher antioxidant activity than flowers, whereas the total phenolic content varied depending on the growing location or cultivar. The material obtained from selected cultivars growing in an orchard had higher antioxidant activity and polyphenol and anthocyanin content than the material obtained from wild plants. Fruit of the ”Haschberg” cultivar and flowers of the ”Sampo” cultivar had the best bioactive properties of the studied samples.

“…The researchers showed the amount found in flowers ranged from 78.96 to 110.51 mg 100 −1 FW (fresh weight), compared with as little as between 3.39 and 9.84 mg 100 −1 FW in fruit. A similar association was demonstrated by Kołodziej and Drożdżal [24], who analyzed the flowers and fruit of elderberry. Elderflowers had a higher content of polyphenolic compounds (from 37.02 to 53.33 mg g −1 DM [dry mass]) compared with elderberries (from 26.84 to 44.8 mg g −1 DM) as well as greater antioxidant capacity than the fruit, which was confirmed using FRAP and DPPH assays.…”

The flowers of the common poppy are used for medicinal purposes, both internally and externally. They are reported to have antispasmodic and antitussive properties, to alleviate inflammatory conditions and soothe anxiety-related digestive problems. The aim of the study was to determine the antioxidant potential and the content of vitamin C, polyphenols, and minerals in infusions made from the petals of the common poppy at different temperatures. The infusions were made at various temperatures (25°C, 70°C, 80°C, and 90°C). The antioxidant potential and the content of polyphenols and vitamin C were determined by spectrophotometric methods. The mineral content was determined using the ICP-OES method. The total polyphenol content ranged from 135.2 to 137.24 ppm and that of vitamin C-from 15.47 to 15.78 mg/100 mL. The temperature of the water used to make the infusions did not appear to have a significant effect on these parameters. The temperature did, however, significantly affect the antioxidant potential of the infusions-the highest antioxidant activity (71.21% DPPH inhibition) was observed in the infusion prepared using water at 80°C. The infusions included in the study contained a number of minerals. No significant effect of temperature was found for the content of K, Zn, Cu, Fe, and Ni in the infusions. On the other hand, the content of Ca in the infusions was significantly correlated with the increasing temperature of the water. It was concluded that poppy petal infusions may serve as a valuable dietary supplement, providing antioxidants and minerals required by the human body to function properly.

In recent years both in the food and the pharmaceutical industries great attention has been focused on plant-origin raw materials rich in natural antioxidants.Elderberry is such a raw material due to its relatively high content of polyphenols, including anthocyanins (Bermudez-Soto and Tomas-Barberan, 2004). ASSESSMENT OF COLOUR CHANGES DURING STORAGE OF ELDERBERRY JUICE CONCENTRATE SOLUTIONS USING THE OPTIMIZATION METHOD ABSTRACTBackground. Elderberries are a source of dietary supplements and bioactive compounds, such as anthocyanins. These dyes are used in food technology. The aim of the study was to assess the changes in colour parameters, anthocyanin contents and sensory attributes in solutions of elderberry juice concentrates during storage in a model system and to determine predictability of sensory attributes of colour in solutions based on regression equations using the response surface methodology. Material and methods. The experiment was carried out according to the 3-level factorial design for three factors. Independent variables included pH, storage time and temperature. Dependent variables were assumed to be the components and colour parameters in the CIE L*a*b* system, pigment contents and sensory attributes.Results. Changes in colour components X, Y, Z and colour parameters L*, a*, b*, C* and h* were most dependent on pH values. Colour lightness L* and tone h* increased with an increase in experimental factors, while the share of the red colour a* and colour saturation C* decreased. The greatest eff ect on the anthocyanin concentration was recorded for storage time. Sensory attributes deteriorated during storage. The highest correlation coeffi cients were found between the value of colour tone h* and anthocyanin contents in relation to the assessment of the naturalness and desirability of colour. A high goodness-of-fi t of the model to data and high values of R 2 for regression equations were obtained for all responses. Conclusion. The response surface method facilitates optimization of experimental factor values in order to obtain a specifi c attribute of the product, but not in all cases of the experiment. Within the tested range of factors, it is possible to predict changes in anthocyanin content and the sensory attributes of elderberry juice concentrate solutions as food dye, on the basis of the lack of a fi t test. The highest stability of dyes and colour of elderberry solutions was found in the samples at pH 3.0, which confi rms the advisability of using an anthocyanin preparation to shape the colour of high-acidity food products, such as fruit fi llings, beverages, desserts.
