Astragalin is a chemical compound. It can be isolated from Phytolacca americana (the American pokeweed) or in the methanolic extract of fronds of the fern Phegopteris connectilis.[1] It is also found in wine.

Astragalin is a 3-O-glucoside of kaempferol.

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
