Chlorogenic acid（327-97-9)

Origin of chlorogenic acid: According to literature records, chlorogenic acid was first found in coffee seeds. As early as 1837, two scientists, Robiquet and Boutron, discovered its existence when looking for acidic substances in crude coffee extract (with green pigment). At that time, this substance had green color in aqueous solution containing ferric chloride. In 1846, Payen found that it changed from yellow to green after being exposed to oxygen in alkaline solution containing amine, so he formally named this substance [chlorogenic acid]. The prefix of Chloro - comes from Greek, which originally means light green, while the root - genic is the source, so chlorogenic acid Chemicalbook Chlorogenic means that it comes from the green extract of coffee. However, in 1909, the high-purity chlorogenic acid crystal was obtained from coffee seeds by Gorter, which was the first time that it was presented to the world in the true face of Lushan Mountain. Gorter also established a color reaction based on ferric chloride as a rapid screening method for chlorogenic acid, and found that chlorogenic acid was not only found in coffee seeds, but also in coffee leaves, latex sap of rubber trees and sunflower seeds. And now. Chlorogenic acid is not only found in coffee, but also produced by almost all higher plants, such as apples, sweet potatoes, tomatoes, pears, apricots, Luoshenhua, oranges, etc. Its content is the highest in coffee
