Alkaloids from Dictyoloma vandellianum: their chemosystematic significance.
The dichloromethane extract from leaves of Dictyoloma vandellianum afforded five alkaloids 2-(14'-hydroxy-14',15'-dimethylhexadecanyl)-4-quinolone, 2-(12'-hydroxy-12'-methyltridecanyl)-3-methoxy-4-quinolone, 2-(12'-hydroxy-12'-methyltridecanyl)-4-quinolone, 2-(14'-hydroxy-14',15'-dimethylhexadecanyl)-3-methoxy-4-quinolone, 6-methoxydictyolomide A, besides the known alkaloid 8-methoxyflindersine and beta-sitosterol. The presence of 2-alkyl-4(1H)-quinolones in D. vandellianum shows strong similarities with the Zanthoxyleae, which contains several 2-alkyl-4-quinolones. Thus, the Dictyolomatoideae apparently occupies a position between the proto-Rutaceae genera and the Spathelioideae, but close to the Zanthoxyleae.
