Caffeic acid is not only contained in a variety of food and Chinese medicinal materials, but also exists in the secondary metabolites of plants, which is an organic acid derived from phenylalanine after deamination to form cinnamic acid. The o-diphenol hydroxyl on the benzene ring is the main active point of caffeic acid, and it will show certain characteristics. In caffeic acid molecules, the stronger the electron absorption ability of the substituent on the benzene ring, the stronger its biological activity will be.
Caffeic acid is mainly used in medicine, health care products, feed, cosmetics and other fields as a raw material with high safety and obvious effect. It has anti-inflammatory, anti-infection, anti-oxidation, antiviral, antibacterial and other biological activities. It is mainly used in the medical field as pharmaceutical intermediates and pharmaceutical raw materials to alleviate or treat a variety of diseases.
With the research on caffeic acid for many years, the biological activity of caffeic acid has been widely concerned, and its application has been increasing.
