Epimagnolin B is a bisepoxylignan isolated from Magnolia fargesii, with anti-inflammatory activity and antiallergic effects. Epimagnolin B inhibits NO production in LPS-activated microglia. Epimagnolin B exhibited antiallergic effects[1][2].
Epimagnolin B exhibits antiallergic effects without affecting the viability of BMMCs[1].
