Astragalin is a naturally occurring flavanoid chemical compound with a yellow colour. It was first isolated from Astragalus sinicus after which it is named.[1]
It can be isolated from Phytolacca americana (the American pokeweed) or in the methanolic extract of fronds of the fern Phegopteris connectilis.[2] It is also found in wine.
Astragalin is a 3-O–glucoside of kaempferol.
