Special Issue Information

Dear Colleagues,

Hundreds of edible berry species are cultivated or grow in the wild around the world. Berry fruits are known to be rich in a variety of bioactive compounds, especially phenolic compounds, including anthocyanins, a well-known antioxidant. Although a series of in vitro and in vivo studies have reported the beneficial effects of berries and their bioactive compounds in the regulation of various cellular functions related to oxidative stress and/or antioxidant activity, much remains to be elucidated to comprehensively understand the antioxidant capacity of berries and their active ingredients, along with their preventive effects against oxidative stress.

In this regard, this Special Issue of Antioxidants will provide an up-to-date perspective of this topic. We invite you to submit your latest research findings related to the antioxidant activity of berries and/or their active components, including both in vitro and in vivo studies, to this Special Issue. We particularly encourage the submission of clinical evidence supporting the role of berries in counteracting oxidative stress in humans. Submissions of review articles related to antioxidant activities of berries are also welcome.

We look forward to your contributions to this topic.

The aim of this study was to compare the antioxidant potential in the fruits of different hybrids of Rubus idaeus and Rubus occidentalis (four hybrids) against the fruit of known cultivars of both species (R. idaeus—three cultivars; R. occidentalis—five cultivars) and, using chemometric analysis, to select factors affecting the level of polyphenols and antioxidant properties. Antioxidant activity was determined using the ABTS, DPPH and FRAP tests. Chemometric analysis enabled the separation of R. idaeus and R. occidentalis cultivars and classified the hybrid R. idaeus/R. occidentalis R1314701 as belonging to the R. occidentalis species. Moreover, two hybrids, Rubus occidentalis/Rubus idaeus R1613411 and R. idaeus/R. occidentalis R1613409, can be classified as a purple raspberry. Crossbreeding species/cultivars of the Rubus genus may result in an increased content of anthocyanins, but on the other hand, it may lead to a reduction in free radical scavenging activity in the ABTS and DPPH. Spearman’s correlations confirm the correlations between the total polyphenol content and antioxidant activity in the DPPH, ABTS and FRAP, as well as the anthocyanin content and antioxidant activity in the ABTS and FRAP tests. Chemometric analysis can be an effective tool in determining the species affiliation of obtained hybrids and cultivars. Full article

Invasive alien plants are typically associated with negative impacts on ecosystems and sometimes on health, but studies also describe their ethnomedicinal usage, particularly by indigenous communities. Given the existing limitations regarding a critical study on the berry-producing invasive plants, this study aims to provide scientific evidence and much-needed updated knowledge on the pharmacologically significant fruits of several berry-producing invasive alien plants. A list of 35 species from 16 families is provided, along with their characteristics, historical medicinal uses, updated biological activities, and available toxicity data. The definitions, terminology, and classification criteria used to describe alien species, specifically the invasive types, are also provided. Most of the berries of the described species exhibit remarkable antioxidant properties due to their abundance of highly reactive molecules, mainly polyphenols and carotenoids. Other biological activities, ranging from antimicrobial, anti-inflammatory, and anti-diabetic to anticancer and neuroprotective activities, have been identified. In contrast, quantitative toxicity issues have been poorly studied for berries from invasive plants. Hopefully, this work will serve as a starting point for further exploration of the molecules from berries of these plants in terms of drug discovery to advance various therapies or other applications.
