The Phenolic Contents and Antioxidant Activities of Infusions of Sambucus nigra L.

Abstract

The aim of this work was to evaluate the antioxidant potential of teas prepared from twenty-four commercially available berries and flowers of Sambucus nigra L. in relation to their phenolic profile, as reflected by the most representative phenolic acids (caffeic, chlorogenic, p-coumaric, ferulic, gallic and syringic acids); flavonols (quercetin, kaempferol, myricetin and rutin); and total phenolic (TPC), phenolic acid (TAC) and flavonoid (TFC) contents. The infusions prepared from elderflowers contained more abundant phenolic compounds than the elderberry infusions. The TPC of these infusions ranged from 19.81 to 23.90 mg of gallic acid equivalents/g dry weight of sample (GAE/g DW) for elderberries and from 15.23 to 35.57 mg GAE/g DW for elderflowers, whereas the TFC ranged from 2.60 to 4.49 mg of rutin equivalents/g dry weight of sample (RUTE/g DW) in elderberry infusions and from 5.27 to 13.19 mg RUTE/g DW in elderflower infusions. Among the phenolic compounds quantified in this study, quercetin (2.07–9.48 mg/g DW) and myricetin (1.17–9.62 mg/g DW) had the highest concentrations in the teas prepared from berries and flowers, respectively. Moreover, the antioxidant potential of elder infusions assessed by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical and ferric reducing antioxidant power (FRAP) assays revealed that the teas prepared from flowers had higher mean DPPH and FRAP activities than the teas prepared from berries. Therefore, elder beverages could be important dietary sources of natural antioxidants that contribute to the prevention of diseases caused by oxidative stress.Electronic supplementary materialThe online version of this article (doi:10.1007/s11130-016-0594-x) contains supplementary material, which is available to authorized users.

“…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].…”

Ultrasound-assisted extraction of medicinal plants and evaluation of their biological activity

“…Oniszczuk et al (2016) conducted ultrasonic extraction of S. nigra at 60°C and established the presence of various phenolic acids and flavonoids. According to Viapiana and Wesolowski (2017), the TPC of S. nigra flowers infusions ranged from 15.23 to 35.57 mg GAE/g DW, whereas Veljković et al (2013) detected TPC of 42.67 g GAE/kg DW. In comparison, Boukhira et al (2015) established TPC of 3.35±0.12 mg GA/g of extract in the ultrasound-assisted extract of S. vulgaris from Morocco and Kiselova et al (2006) established TPC for infusion of A. linearis of 437.90±1.11 µM QE.…”

“…The results were in accordance with the total phenolic content established. Other authors determined the antioxidant activity of S. nigra flower infusions from 0.57±0.07 to 0.92±0.01 mM TE/g DW toward DPPH (Viapiana and Wesolowski, 2017). According to the ABTS assay (Table 2), the highest results were established for S. nigra and A. linearis -144.54±2.21 and 83.01±1.36 μM TE/g DW, respectively and the lowest was evaluated in C. erythraea 27.37±0.12 μM TE/g DW.…”

“…In addition, it could be inferred that all values obtained here might vary depending on influence of parameters mentioned early, besides type and quantity of solvent and method used in extraction. Antioxidant effect reflects cumulative action of all antioxidants present in extract, hence it is considered fundamental parameter to establish health benefits of food products (Viapiana &, Wesolowski, 2017).…”
