Application of plant polyphenols in environmental protection and agricultural production
植物多酚在环境保护与农业生产中的应用

Plant polyphenols,the secondary metabolites in plant,contain many phenol-hydroxyl groups.They can bind with protein,alkaloids and polysaccharides,and consequently,exhibit an astringent property.Plant polyphenols can also bind with metal ions to form polyphenol-metal complexes,which are probably soluble or precipitated,depending on the type of plant polyphenols.Up to now,about 600 plant polyphenols have been found.Plant polyphenols can be applied widely in environmental pollution control and agriculture production.
