Description
Summary:	Dictyoloma vandellianum afforded five alkaloids 2-(14′-hydroxy-14′,15′-dimethylhexadecanyl)-4-quinolone, 2-( 12′-hydroxy- 12-methyltridecany)-3-methoxy-4-quinolone, 2-( 12′-hydroxy- 12′-methyltridecanyl)-4-quinolone, 2-(14′-hydroxy-14′,15′-dimethylhexadecanyl)-3-methoxy-4-quinolone, 6-methoxydictyolomide A. The chemosystematic relationship is discussed. 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 β-sitosterol. The presence of 2-alkyl-4(1 H)-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.
