Introduction:

The bark of Quercus plants in the Fagus family was ground into powder, washed with hot salt water, extracted with dilute ammonia, and neutralized with dilute sulfuric acid. The filtrate is boiled to precipitate crystals. It can be extracted from Liliaceae plant onion (AllChemicalbookiumcepa) with 95% ethanol; it can also be extracted from rutin (rutin) extract and quercetin, isoquercitrin, anisin, hyperoside, quercetin, and melanitin, etc. It is obtained by hydrolysis of rutin decomposing enzyme or acidic aqueous solution.

 

Production methods:

1. Recovery of isoquercetin from bioflavonoids

2. Preparation method of quercetin and isoquercetin derivatives

3. Quercetin derivatives and their medical uses

4. Enzymatic hydrolysis of rutin to prepare isoquercetin and quercetin

5. A method for extracting quercetin-7-O-rhamnoside
