Unlocking dandelion (Taraxacum mongolicum)’s hidden treasure: enzyme-hydrolyzed polysaccharides with enhanced bioactivity for ROS defense and developmental protection
Dandelion (Taraxacum mongolicum) is widely used as a natural additive in food, pharmaceutical, and cosmetic industries. In this study, we applied pectinase-mediated enzymatic hydrolysis to dandelion to enhance its bioactivity. The results showcased that enzyme treatment disrupted the cell‐wall matrix, turning the raw material from yellowish-green to dark brown and releasing bound polysaccharides. The hydrolyzed extract polysaccharide (EDP) exhibited higher polysaccharide content (180.72 mg/g), an improved water extraction rate (33.22%), and a reduced molecular weight. In vitro assays revealed superior antioxidant performance in EDP—84.06% DPPH and 59% hydroxyl-radical scavenging—along with stronger reducing power. Furthermore, in an AAPH-induced zebrafish model, EDP more effectively supported heart rate and normal development while notably reducing reactive oxygen species (ROS) accumulation, lipid peroxidation, and cell death. Collectively, these findings highlight the potential of enzymatic hydrolysis as a strategy to boost the bioactive properties of dandelion, offering valuable insights for its use in functional foods and natural antioxidants.
期刊介绍：
Chemical and Biological Technologies in Agriculture is an international, interdisciplinary, peer-reviewed forum for the advancement and application to all fields of agriculture of modern chemical, biochemical and molecular technologies. The scope of this journal includes chemical and biochemical processes aimed to increase sustainable agricultural and food production, the evaluation of quality and origin of raw primary products and their transformation into foods and chemicals, as well as environmental monitoring and remediation. Of special interest are the effects of chemical and biochemical technologies, also at the nano and supramolecular scale, on the relationships between soil, plants, microorganisms and their environment, with the help of modern bioinformatics. Another special focus is the use of modern bioorganic and biological chemistry to develop new technologies for plant nutrition and bio-stimulation, advancement of biorefineries from biomasses, safe and traceable food products, carbon storage in soil and plants and restoration of contaminated soils to agriculture.
This journal presents the first opportunity to bring together researchers from a wide number of disciplines within the agricultural chemical and biological sciences, from both industry and academia. The principle aim of Chemical and Biological Technologies in Agriculture is to allow the exchange of the most advanced chemical and biochemical knowledge to develop technologies which address one of the most pressing challenges of our times - sustaining a growing world population.
Chemical and Biological Technologies in Agriculture publishes original research articles, short letters and invited reviews. Articles from scientists in industry, academia as well as private research institutes, non-governmental and environmental organizations are encouraged.
