“…Certainly, to date, phenolic content in edible flowers is difficult to find, and for the most part, is related to antioxidant activity. For example, Brighente et al [29] described the antioxidant activity of extracts and the fractions of six vegetal species of Baccharis (Asteraceae). However, in that work, quercetin was detected in species of the Asteraceae family, while here it was not (see Table 1).…”

The phenolic compound composition, antioxidant activity and impact on cell viability of edible flower extracts of Allium schoenoprasum; Bellis perennis; Cichorium intybus; Rumex acetosa; Salvia pratensis; Sambucus nigra; Taraxacum officinale; Tragopogon pratensis; Trifolium repens and Viola arvensis was examined for the first time. Total phenolic content of the flowers of these plants fell between 11.72 and 42.74 mg of tannin equivalents/kg of dry matter. Antioxidant activity ranged from 35.56 to 71.62 g of ascorbic acid equivalents/kg of dry matter. Using the Human Hepatocellular Carcinoma cell-line (HepG2) and the Human Immortalized Non-tumorigenic Keratinocyte cell line (HaCaT), we assessed cell viability following a 3 day incubation period in media containing 25, 50, 75 and 100 μg/ml of total phenolic compounds using a colorimetric MTT assay. These three properties could make the herbs useful in treatment of various diseases like cancer. The tested extracts had significant effects on cell viability, but the effects were dependent not only on the phenolic compound concentration and the edible flowers species, but also on the phenolic compound and antioxidant profiles. In addition, responses differed between cell lines.

“…The TPC was expressed in gallic acid equivalent (GAE) per dry weight [mg GAE g −1 DW]. The TFC was determined according to method described by Brighente et al [21]. Briefly, 0.5 mL of 2% aluminium chloride (AlCl 3 ) in methanol was mixed with the same volume of methanol solution of fruit and berry extracts.…”

-Introduction. Cacak is the large fruit production region in Serbia; it presents an enormous diversity represented by different fruit species, highlighting apricot and small fruits. The objective of this work was to investigate and compare the main temperate fruit and berry quality attributes in eight species and their cultivars grown under similar environmental conditions. Materials and methods. The species evaluated were blackberry, woodland and domesticated strawberry, red and white currant, jostaberry (Ribes nigrum × Ribes uva-crispa), gooseberry and apricot. Standard laboratory procedures and methods were used to determine fruit or berry weight, soluble solids content (SSC), acidity (TA) and contents of bioactive compounds. Results and discussion. Significant and strong differences among species were detected for all properties evaluated, especially for fruit or berry weight. The fruits of apricot contained the highest soluble solids content (15.28• Brix) and ripening index (RI) value (22.49), whereas blackberry is a very rich source of acidity (1.47%), antioxidant power [161.88 mg AA g −1 dry weight (DW)], total phenolics (110.07 mg GAE g −1 DW) and total flavonoids (51.55 mg RUE g −1 DW). A strong relationship between some quality attributes was detected. Also, the cultivar per se (genotype) behaved as the most influencing factor determining fruit and/or berry chemical composition. Conclusion. Results of our work confirmed that fruits or berries evaluated are rich in primary and secondary metabolites. They showed desirable characteristics for the fresh consumption, while the most of them had high contents of natural antioxidants and may be recommended as a good raw material for the food industry.Keywords: Serbia / apricot (Prunus armeniaca) / Ribes spp. / Fragaria spp. / flavonoids / nutritional value Résumé -Acidité, teneur en matières solubles et en composés phénoliques et activité antioxydante de fruits et baies cultivés en Serbie.

Fruit quality attributes were studied for two consecutive years in seven blackberry cultivars grown in a Serbian climate and on acidic soil. Physical parameters [berry weight (BW), size and shape] and chemical parameters [soluble solids content (SSC), acidity, total phenolic (TPH) and flavonoid content (TFC) and total antioxidant capacity (TAC)] were evaluated. A high variability was found in the set of the evaluated blackberry cultivars and significant differences were found among them in all studied quality attributes. Year-by-year variations were observed for all quality traits, except berry length (L) and berry shape index (BSI). A high correlation was found among TPH and TAC. In addition, most of cultivars had good adaptation capability and respectable fruit quality attributes, and also had good potential as a commercial crop for fresh and processing markets and future breeding programs.
