“…2.59 followed by acetone (2.22) and water (1.99) extracts. The present finding is in agreement with the previous study [19], which reported that ethanolic extracts of shrubs (P. tridentatum, C. scoparius and Erica spp.) also showed higher extract yields than the aqueous extracts.…”

“…The DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenging assay was used to evaluate the antioxidant activity of the samples [16]. Briefly, to 100 µL of each sample, 3.9 mL of a 0.1 mM DPPH (Sigma-Aldrich, USA) methanolic solution were added, being this mixture stirred until complete homogenization.…”

“…The control solution consisted in 100 µL of methanol with 3.9 mL of the DPPH solution. The reaction mixtures were kept at room temperature in the absence of light for 30 min, time after which the absorbances were read at 517 nm using a spectrophotometer (Helios-Omega, Thermo Scientific, USA) [16].…”

Honey and propolis are natural substances produced by Apis mellifera that contain flavonoids, phenolic acids, and several other phytochemicals. The aim of this study was to phytochemically characterize three different types of honey and propolis, both separately and mixed, and to evaluate their wound-healing activity. Total phenolic compounds and flavonoids were determined using the Folin-Ciocalteu's and aluminum chloride colorimetric methods, respectively. The antioxidant activity was evaluated by both the DPPH free radical scavenging assay and β-carotene bleaching test, and the anti-inflammatory activity was determined by a protein denaturation method. To evaluate the wound-healing activity of the samples, NHDF cells were subjected to a wound scratch assay. The obtained results showed that dark-brown honey presents a higher concentration of phenolic compounds and flavonoids, as well as higher antioxidant and anti-inflammatory activities. Propolis samples had the highest concentrations in bioactive compounds. Examining the microscopic images, it was possible to verify that the samples promote cell migration, demonstrating the wound-healing potential of honey and propolis.

“…Regarding berries supplementation and synergy, it is recently reported that gallic acid, quercetin, ellagic acid, and cyanidin have a market antioxidant activity [161,162], due to the synergistic effects between the numbers of aromatic ring mixtures. In addition, polyphenols present in berries can interact between them, improve their antioxidant properties, and, therefore, increase human's health benefits [162]. According to our knowledge, no studies were found related with pharmacological interactions and berry supplementation.…”

This chapter is based in the compilation and analysis of different in vitro, preclinical, and clinical studies, which explored the potential beneficial bioactivity of supplementation with berries on some alterations in the central nervous system (CNS). The last section of the chapter describes the possible mechanisms of action of polyphenols, anthocyanins, and other compounds present in berries as well as their relationship with anxiety, depression, and Alzheimer's (AD) and Parkinson's diseases (PD) and their implication in the prevention of cognitive decline and senescence motor functions. Electronic databases as Springer, PubMed, Scopus, and Elsevier were used. Papers were selected by topic specially those related with berries, year of publication, and authors. The present chapter evidenced the potential health effect as neuroprotector of different berries and their bioactive compounds mainly flavonoids, polyphenols, and anthocyanins, on diseases such as anxiety, depression, and Alzheimer's and Parkinson's diseases. In conclusion, for human nutrition berry fruit supplementation might be an excellent source of antioxidant and alternative for prevention and reduction of symptoms in diseases such as anxiety, depression, Alzheimer's, and Parkinson's.
