Batatasin I is a natural product that can be isolated from tuberous roots of Dioscorea batatas, with antifungal activity and anti-inflammatory effects.
Batatasin I shows anti-inflammatory effects via the inhibition of both eicosanoid generation and degranulation reaction in activated mast cells[1].
