Hot sale 149-91-7  low price Gallic acid  in china

Gallic acid (GA) is a component of hydrolyzable tannin, also known as gallic acid, chemical name 3,4, 5-trihydroxybenzoic acid. The content of gallic acid in Yunnan Pu'er tea is relatively high, and it has many biological effects such as antibacterial, anti-inflammatory, anti-tumor, and anti-mutation.

gallic acid itself has significant antioxidant effect, and also has many effects such as anti-tumor, trypanosomiasis, liver protection and anti-hepatitis B virus. Recent studies have pointed out that gallic acid may be one of the effective components of Pu 'er tea to inhibit cholesterol synthesis by HepG2 cell lines. On the whole, the content of gallic acid (9.01 mg/g) in Pu 'er tea is higher than that of other traditional Chinese medicinal materials. In this sense, gallic acid is one of the important physiological active components of Pu 'er tea.

made from gallnut. The main component of gallnut is tannic acid, which belongs to hydrolyzed tannin, which can be dissolved in hot water and has astringent taste. It is an amorphous complex organic matter. Chinese gallnut tannic acid is a complex mixture formed by the combination of gallic acid, double acid and glucose in the form of glycosides or esters. Tannic acid is hydrolyzed under pressure to produce gallic acid and glucose. When hydrolyzing, gallate is first generated, and then gallic acid is hydrolyzed from bisgallate. The hydrolysis temperature is 133-135 ℃, and the pressure is 0.18-0.2MPa. From the pressure increase to 0.18MPa, the reaction is maintained for 2h to reach the end point. Compared with normal pressure hydrolysis, sulfuric acid and steam can be saved, and the production capacity can increase 25%.
