Abstract
BACKGROUND:
Polyphenolic-rich chokeberry extracts and juice could provide health benefits in humans. Moreover, by-products after processing stand out as a potential new source of valuable compounds. OBJECTIVE:
The research aimed to evaluate in vitro bioactivity of chokeberry fruit extract, juice, and waste extract (material remaining after juice processing) based on their chemical composition and molecular docking analysis. METHODS:
Spectrophotometric methods were used to determine the phenolics, anthocyanins, flavonoids, and proanthocyanins content in freeze-dried samples. Additionally, individual anthocyanins, flavonoids, and sugars were identified through HPLC analysis. The antioxidant capacity was tested using two in vitro methods and assessing antimicrobial activity. The effects of tyrosinase and acetylcholinesterase inhibition were examined using spectrophotometric methods. Molecular docking analysis identified the interaction of chokeberry components with the active sites of these enzymes. RESULTS:
The waste extract exhibited the most robust antioxidant activity within the DPPH system. While bactericidal activity was absent across all chokeberry preparations, they demonstrated inhibitory effects on specific microbiological strains relevant to the gastrointestinal tract. Results revealed the chokeberry products’ ability to inhibit tyrosinase and acetylcholinesterase. Molecular docking confirmed the strong interactions between chokeberry compounds and these enzymes. CONCLUSION:
The results indicate the potential of chokeberry products and by-products as valuable resources for pharmaceutical applications.
期刊介绍：
The main objective of the Journal of Berry Research is to improve the knowledge about quality and production of berries to benefit health of the consumers and maintain profitable production using sustainable systems. The objective will be achieved by focusing on four main areas of research and development:
From genetics to variety evaluation
Nursery production systems and plant quality control
Plant physiology, biochemistry and molecular biology, as well as cultural management
Health for the consumer: components and factors affecting berries'' nutritional value
Specifically, the journal will cover berries (strawberry, raspberry, blackberry, blueberry, cranberry currants, etc.), as well as grapes and small soft fruit in general (e.g., kiwi fruit). It will publish research results covering all areas of plant breeding, including plant genetics, genomics, functional genomics, proteomics and metabolomics, plant physiology, plant pathology and plant development, as well as results dealing with the chemistry and biochemistry of bioactive compounds contained in such fruits and their possible role in human health. Contributions detailing possible pharmacological, medical or therapeutic use or dietary significance will be welcomed in addition to studies regarding biosafety issues of genetically modified plants.
