Small Berries - Attractive Source Of Bioactive Compounds For Consumers

Abstract

Small berries nowadays start be very popular not only in medicine, pharmacy but also in gastronomy, due to the high amount of biologically active compounds and pleasant sensory characteristic. These kinds of fruits is rich for natural colorants, flavonoids, phenolic acids, vitamins and mineral compounds. Aim of this study was to investigate the biological activity (antioxidant activity, natural colorants, polyphenols and flavonoids) of selected kind of small berry fruits -acai, goji, schisandra, mulberry and sea buckthorn berries. The values of antioxidant activity by DPPH method was the highest in sea buckthorn berries 8.96 ±0.09 mg TEAC/g; values by molybdenum reducing antioxidant power method ranged from 94.69 (sea buckthorn) to 337.56 (acai) mg TEAC/g. The total polyphenol content in evaluated small berries ranged from 4.29 (mulberry) to 19.66 (acai) mg GAE/g; total flavonoid content was from 0.86 (goji) to 13.01 (acai) µg QE/g. Results showed that goji, schisandra and sea buckthorn berries are also rich for carotenoids, with the highest value in goji berry -0.38 mg/g. In acai berry was detected high level of total anthocyanins -10.74 mg/g. The results showed that small berries can be important tools for increasing nutritional value of diet, foods and can improve sensory properties of these products.

Characterization of the Omija (Schisandra chinensis) Extract and Its Effects on the Bovine Sperm Vitality and Oxidative Profile during In Vitro Storage

“…The presence of carotenoids in S. chinensis has not been studied in detail before. Our results suggest that carotenoids comprise a relatively small fraction of the Omija extract, agreeing with Ivanišová et al [ 35 ] who state that the concentration of carotenoids in S. chinensis was lower in comparison to sea buckthorn or goji. As such, we may hypothesize that the biological activity of S. chinensis may not be attributed to tetraterpenoids.…”

“…The biochemical assessment of the Omija extract revealed that the berry is a rich source of phytochemicals, particularly phenolic compounds, complementing the findings by Ivanišová et al [ 35 ]. Mocan et al [ 36 ] elected a similar experimental approach to assess the general composition of S. chinensis leaves and fruits.…”

“…While in the DPPH assay, ROS-quenching molecules are predominantly represented by mineral compounds, vitamins, and poylphenols, in the MRAP protocol, the reduction of Mo VI to Mo V is primarily executed by polyphenols and carotenoids. As such, it is recommendable to assess the antioxidant activity of a sample by using more than one method [ 35 ].…”

Methodological Approach to the Elaboration of the Analytical Procedure of the Antioxidant Activity Determination of the Schisandra chinensis (Turcz) Baill. Extracts

“…Herbal preparations are used as an alternative source of medicines to mitigate the diseases associated with oxidative stress (Priya and Nethaji, 2015). The free-radical scavenging activity of the extracts was evaluated using the widely used 2,2-diphenyl-1picrylhydrazyl (DPPH) test (Sheng et al, 2011;Mocan et al, 2014;Ivanišová et al, 2017;Vergun et al, 2018Grygorieva et al, 2020;Shelepova et al, 2020;Tvrdá et al, 2020;Mňahončaková et al, Vinogradova et al, 2021). The DPPH assay provides an easy and fast mode to estimate antioxidant activity.…”

Effect of Alginite in the Form of ALGEXr 6 Preparation on the Biomass Formation and Antioxidant Activity of Some Medicinal Plants

“…Medicinal herbs are used due to their health benefits, special aroma, taste and are considered one of the richest sources of bioactive compounds (Shanayda and Korablova, 2015;Shymanska et al, 2018;Mňahončáková et al, 2019;Ivanišová et al, 2017Ivanišová et al, , 2020. The commercial development of plants as sources of antioxidants to enhance health and food Effect of alginite in the form of ALGEX r 6 preparation on the biomass formation and antioxidant activity of some medicinal plants preservation is of current interest (Rice-Evans et al, 1997).…”
