Isolation, structural characteristics and biological activities of main functional components from Citrus reticulata...

Citrus reticulata Blanco peels are a common edible fruit peel, featuring rich nutritional properties and diverse physiological activities. It is rich in bioactive components such as polysaccharides, flavonoids, alkaloids, essential oils, and phenolic acids. Citrus reticulata Blanco peels polysaccharides (CrBpps) are among its major bioactive substances. CrBpps possess a variety of biological activities, including antioxidant, anti-liver steatosis, anti-obesity, and immune-enhancing effects. The extraction, purification, structural characterization and biological activity of CrBpps have been studied, but the research and discussion on more efficient extraction and purification methods, structural analysis methods, the relationship between structure and biological activity, toxicology are still relatively limited. This article reviews the extraction, purification, structural characterization, biological activities and other potential values of CrBpps, and elaborates the beneficial effects of CrBpps on health and its great potential in practical applications.
