“…It is also rich in different nutrients, some of which contribute to orosensory properties. Empetrum extract has been demonstrated to protect cells against H 2 O 2 -induced cell damage via antioxidant properties by scavenging reactive oxygen species and by enhancing antioxidant enzyme activities, and it displays anti-inflammatory and anticancer activity, and has a positive effect on lipid metabolism [201,202]. In addition, Empetrum nigrum ssp.…”

BACKGROUND: Interest in the wild berries of dwarf shrubs (wild berries) is increasing. Therefore, an update is important regarding how these species react to and interact with different climatic factors, and on how the predicted climatic changes will affect their distribution, growth and content of compounds affecting health. OBJECTIVE: To systemize knowledge of the Ericaceae and Empetraceae wild berry species. METHODS: A review of literature covering the above topics. CONCLUSION: This review includes five wild berry species and their subspecies: Vaccinium myrtillus, Vaccinium vitisidaea, Vaccinium uliginosum, Vaccinium oxycoccos with ssp. microcarpon, and Empetrum nigrum with ssp. nigrum, hermaphroditum and japonicum. They have been and still are collected in the wild, by local households and industry. The berries have high content of biological compounds of interest for human health. Despite the increasing interest in and demand for these wild berries, domestication attempts have been rare. The species often grow together and are competitors. Which species dominate depends on soil conditions and is determined by small differences. The changing climate and various disturbances will also influence the distribution patterns of wild berries and competing plant species. Semi-cultivation in the natural habitat is probably the best solution for viable and sustainable commercial exploitation of these resources, at least if they are sold with the label "wild berries". However, these species are easily propagated by fresh cuttings, and they can grow on arable land, adapting soil conditions to fit their growing preferences. Such cultivation, to our knowledge has not yet been performed on a large economic scale.

“…In both cases, health benefits are associated with high amounts of secondary metabolites like polyphenols (flavonoids, anthocyanins, flavonols, and phenolic acids) . There is a wide range of health benefits, from antioxidant properties to anti‐inflammatory and anti‐hypertensive effects, cardioprotective effects, and blood glucose regulation . Several studies have reported that diet is a very promising path to prevent metabolic syndrome.…”

Biotic elicitation as a tool to improve strawberry and raspberry extract potential on metabolic syndrome‐related enzymes in vitro

Background Raspberry and strawberry are high value‐added food products that can contribute to human health due to the abundance of polyphenols that they contain. Polyphenols are secondary metabolites and therefore devoted to improve plant adaptation, these polyphenol profile can be induced applying different stimuli, such as certain bacteria. The aim of this study was twofold: (i) to evaluate the ability of two bacterial strains to modulate secondary metabolisms in strawberry and raspberry, and (ii) to explore the ability of plant extracts to modify enzyme activities related to metabolic syndrome. Results Total phenolic and anthocyanin content was higher in strawberries than in raspberries, despite similar antioxidant capacities. Strawberry extracts performed better on the tested enzymes, except on α‐glucosidase inhibition capacity. Bacillus amyloliquefaciens stabilized the effects of extracts at different points in time, and Pseudomonas fluorescens modified plant metabolism after more inoculations (spring) in both species, improving the effects of raspberry extracts on α‐glucosidase, COX1, and COX2, and of strawberry on α‐amylase and COX1. Conclusion It is good to include these two fruits in the diet because they improve the activity of metabolic syndrome‐related enzymes. Applying either strain during plant growth modifies the bioactive profile of the plants, improving the effects of the fruit extracts on human health. © 2018 Society of Chemical Industry

“…[1][2][3] Studies show that high amounts of antioxidants are present in the crowberry. 1,4,[5][6][7][8][9] The total concentration of antioxidant activity in the crowberry was reported to be similar to black currant and blackberry and greater than blueberry and raspberry. 1,10,12,13 In addition, studies show that the crowberry is a great source of anthocyanins with yields similar to the bilberry, which contains the highest amount of anthocyanin of eleven common berries examined.…”

Wildberries are recognized worldwide for their nutrition potential, especially for polyphenols such as anthocyanins and flavonoids, which are known as antioxidants. The crowberry, Empetrum nigrum found in northern climates, is a wildberry that has the potential to be used in natural health and cosmetics products due to its high antioxidant activity. This study is focused on antioxidant active crowberries collected from the Basse-Côte-Nord in the province of Que´bec. The crowberries were analyzed by techniques suitable for a remote region such as the Basse-Côte-Nord, which has limited access to chemicals, equipment and transportation. Two different extraction processes were examined: conventional methods, such as solid-liquid extraction, and unconventional extraction methods such as microwave-assisted extraction. Multiple parameters were tested, including solvent type, solvent-water ratios, liquid/solid ratios, time and temperature. The extracts were analyzed using the Folin-Ciocalteu reagent assay for total phenolic compounds, the pH differential method for total monomeric anthocyanins and the 2,2-diphenyl-1-picrylhydrazyl free radical method for antioxidant activity. The results indicated that, although the ethanol mixtures with water solvent generally gave the highest yield, water extraction gave a significant yield as well. Results also indicated that, compared to the solid-liquid extraction method, the microwave-assisted extraction method allowed for generally smaller liquid:solid ratio (75:1 mL/g compared to 25:1 mL/g with the exception of antioxidant activity) and therefore less solvent. It also allowed for less extraction time (1-5 h compared to 5 min).
