Dehydroleucodine is a sesquiterpene lactone isolated from Artemisia douglasiana. Dehydroleucodine is a mast cell stabilizer that inhibits tmast cell degranulation induced by compound 48/80. Dehydroleucodine inudces cells apoptosis, and has gastric ulcer inhibition and antileukemic effects[1][2][3].

Dehydroleucodine is a sesquiterpene lactone isolated from Artemisia douglasiana Besser; mast cell stabilizers. An extract from the plant is widely used in Cuyo region (Argentina) as folk medicine for the treatment of gastric ailments. The compound prevents gastric and duodenal damages in response to necrosis-inducing agents. Stabilization of mast cells may be a key mechanism to protect the gastrointestinal tract from injury and ulceration. Recentlyit was established th at dehydroleucodine and xanthatin inhibit mast cell degranulation induced by compound 48/80.
