Acridone and furoquinoline alkaloids from Teclea gerrardii (Rutaceae: Toddalioideae) of southern Africa

The stem bark of Teclea gerrardii has yielded two acridone alkaloids, tegerrardins A-B 1-2, together with known acridone 3-5 and furoquinoline 6-7 alkaloids, and a known aminobenzophenone 8. Arborinine 3 and evoxine 6 display moderate antiplasmodial activity.
