RESUMO
Morus alba, a traditional economic crop, is also a significant medicinal plant. The branches(Mori Ramulus), leaves(Mori Folium), roots and barks(Mori Cortex), and fruits(Mori Fructus) of M. alba are rich in chemical components, such as alkaloids, flavonoids, flavanols, anthocyanins, benzofurans, phenolic acids, and polysaccharides, and possess hypoglycemic, hypolipidemic, anti-inflammatory, anti-tumor, anti-microbial, liver protective, immunoregulatory, and other pharmacological activities. This study analyzed the sources, classification, and functions of the main chemical components in M. alba and systematically summarized the latest research results of essential active components in M. alba and their pharmacological effects to provide references for in-depth research and further development as well as utilization of active components in M. alba.
