Abstract:

Loquat (Eriobotrya japonica) is a plant of the Rosaceae family valued for both its nutritional and medicinal properties. Its fruits, leaves, seeds and flowers are rich in various bioactive compounds, such as flavonoids, phenolic acids, triterpenic acids, essential oils and polysaccharides. These substances confer multiple pharmacological activities to loquat, including antioxidant, anti-inflammatory, antitumor, hypoglycemic, and lung-protective effects. The content and composition of these bioactive compounds are crucial determinants of loquat quality and efficacy, and their accumulation is jointly regulated by complex internal mechanisms and external environmental factors. This systematic review summarizes recent research progress on the types and functions of major bioactive compounds in loquat, focusing on advances in their biosynthetic pathways, key enzyme gene regulation, specific accumulation patterns, and molecular regulatory mechanisms. It highlights existing gaps in understanding, such as unclear mechanisms and insufficient investigation of multifactorial interactions, while outlining future directions including multi-omics integration analysis, gene editing applications, and industry-academia-research collaboration. These efforts aim to provide theoretical support for the efficient utilization of loquat bioactive components and industrial value enhancement.
