Teclea verdoorniana

Furoquinoline Alkaloids.—Well-known furoquinoline alkaloids have been identified for the first time in twelve species of the Rutaceae (see the Table 2.5.8,9,11—13,15,16 on p an(j rare trimethoxydictamnine halfordinine (1 R1 = R2 = R3 = OMe) has been obtained from Araliopsis tabouensis2 and from Teclea verdoorniana.12 The isolation of y-fagarine and skimmianine from Tylophora asthmatica (Asclepiadaceae)14 and skimmianine from Datura stramonium (Solanaceae)4 is of considerable taxonomic interest. 

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...
