Natural Ferulic Acid Introduction
Natural Ferulic Acid is a kind of phenolic acid. It exists widely in plants in nature. Often cross-linked with lignin and polysaccharides to form part of the cell wall of plants, rarely in a free state. Its chemical name is 4-hydroxy-3-methoxycinnamic acid (C10H10O4, relative molecular mass 194.19). It is a derivative of cinnamic acid (ie, cinnamic acid, 3-phenyl-2-acrylic acid).
There are both cis and trans structures. Trans-ferulic acid is white to slightly yellow crystals. The cis form is a yellow oil, often in the form of square crystals or fibrous crystals. Generally refers to its trans body, the melting point is 174 ℃.

Source
natural source
It is contained in various plants such as Umbelliferae, Ranunculaceae, and Gramineae. For example, Angelica, Chuanxiong, Cimicifuga, Sanleng, and so on.
chemical synthesis
The basic raw material prepared by chemical synthesis is vanillin. The following two organic reactions are mainly applied.
1. Knoevngael reaction
The raw materials are malonic acid and vanillin. The solvent is anhydrous pyridine, and the catalyst is piperidine.
2. Wittig-Horner reaction
In a strong base system, triethyl phosphite acetate and acetyl vanillin react. After acidification with concentrated hydrochloric acid, the product was obtained.
Biosynthesis
Use several microorganisms. Transformation of precursor substances of ferulic acid. For example, eugenol cinnamate was extracted from clove oil and transformed.
Natural Ferulic Acid Application
In the field of medicine
It has the effects of anti-oxidation, scavenging free radicals, anti-inflammatory, pain relief, anti-ultraviolet radiation, and improving human immunity. Drugs with corresponding efficacy have also been gradually developed.
In the food industry
At present, Japan has approved its use as a food antioxidant. The U.S. and some European countries have also begun to adopt some substances with a higher content as antioxidants to preserve and preserve food. It is also widely used as a food additive.
In the cosmetics industry
Natural Ferulic Acid is favored by the cosmetic industry. The reason is that it has a strong antioxidant and scavenging effect on oxygen free radicals. It also has the effect of inhibiting the activity of tyrosinase, which can delay skin aging and whiten the skin. In addition, it also has sun protection. It has good ultraviolet absorption around 290-330 nm, which can prevent and reduce the damage to the skin caused by ultraviolet rays of this wavelength.
