A number of simple acridones have been obtained from new sources. Thus, acridone itself is a constituent of Thamnosma montana,13 and minor components of the root bark of Teclea verdoorniana include l,3-dimethoxy-A/-methylacridone (29 R = Me) and tecleanthine (30).12...

Deoxygenated products have a restricted distribution. Acridone itself (1) was isolated from Toddalia acukata (97) and Thamnosma montana (98), which also contains 10-methylacridone (30) (99, 100). Alkaloids lacking oxygenated substitution at C-3 include 1-hydroxyacridone, 1,7-dihydroxyacridone, and 1,8-dihydroxyacridone derivatives. It should be noted that 1-methoxy-10-methylacridone (31) and 1,8-dihydroxyacridone (32) were isolated from Samadera aff. bidwillii, the only species of the Simaroubaceae which has afforded this type of secondary metabolite (101).
