Arctiin

Arctiin is a lignan found in many plants of the family Asteraceae, particularly the greater burdock (Arctium lappa) and Centaurea imperialis, and in Trachelospermum asiaticum, Saussurea heteromalla, and Forsythia viridissima. It is the glucoside of arctigenin.

Arctiin and arctigenin have shown anticancer effects in animal research. They have been found to act as agonists of the adiponectin receptor 1.
