Properties and stability
Use and store according to specifications. It will not decompose and avoid contact with oxides.
Storage method
Seal and store in a ventilated, dry place to avoid contact with other oxides.
Synthesis method
Mainly extracted from plants, it is abundant in gallnuts produced by Javanese sumac, water chestnut fruits, terminalia fruits, and eucalyptus globulus leaves. The raw materials are usually defatted. and then leached with alkaline aqueous solution orPure ellagic acid can be obtained by leaching with ethanol, then removing water-soluble proteins and gliadins, and then using enzymes to decompose and remove sugar ligands.
Purpose
1. Used in medicine and cosmetics as an antioxidant, with anti-cancer and virus-inhibiting effects.
2.Ellagic acid has anti-cancer/anti-mutation properties, has an inhibitory effect on human immunodeficiency virus, and is effective against a variety of bacteria and viruses. Inhibitory effect, antihypertensive and sedative effects.
