How is caffeic acid prepared?

Caffeic acid is a phenolic substance mainly in the form of glucosides and esters. It is not only an intermediate product of phenylpropane metabolism pathway in tobacco, but also a metabolite of lignin synthesis pathway. In industrial applications, caffeic acid has a yellow crystal appearance. It can be prepared by 3, 4-dihydroxybenzaldehyde, 3-methoxy-4-hydroxybenzaldehyde, 3, 4-dimethoxy-benzaldehyde, 3, 4-methylenedioxy-benzaldehyde and substituted cinnamate ester through condensation reaction, demethylation reaction and hydrolysis reaction.

Caffeic acid as common phenolic compounds in the cosmetics, medicine and other fields has been widely used in, caffeic acid in the field of cosmetics is safe to use, it has a wide range of antibacterial, antiviral activity, antioxidant effect, also can absorb ultraviolet light, in the medical field, often used in medical, surgical bleeding, bleeding, obstetrics and gynecology can also be used to reduce the fatty acids, resistance to leukemia, Regulate immunity, resist cancer, etc. Caffeic acid plays an important role in cosmetics, medicine and other fields. Through the introduction of Hangzhou Weiblai biology, we can have more understanding of the characters, sources and applications of caffeic acid, so that we can also have more cognition of its application.
