In onion,spiraeoside (quercetin-4′-O-β-D-glucoside),rutin and quercetin and 3 other not identified compounds were found as the major constituents. Significant cultivar differences were found in total polyphenol and main flavonoid antioxidants. And during storage, an increase in flavonoids could be observed, especially at a laboratory temperature (22°C) compared to storage at a lower temperature.
KINGHERBS' onion extract aims at total polyphenol and main flavonoid antioxidants in the onion bulb. The main ingredients are the following:

KINGHERBS choose the right species of onion, and after an intended storage in a special condition to increase its active ingredients, we extract it with only grain ethanol. Thus assure us the best quality,with highest spiraeoside and flavonoids.The Onion extract is hard to be dried into solid,KINGHERBS offer mainly onion paste extract instead of dry powder extract. 
Onions are good for Psoriasis treatment,it is a good substitute for steroids. The anti-oxidant, anti-inflammatory and healing characteristics of the onion help recuperate the natural texture of damaged skin, and unlike steroid creams,can be applied anywhere on the body and used by patients of all ages.It also proves effective in treating acne.
Onion extract can be used in feed as source of polyphenol & flavonoids in large quantity.
