| Popis: | The phytochemical investigation of the roots of E. almawillia is reported for the first time. Chromatographic fractionation of the methanol extract allowed the isolation of the alkaloids 3,3-diisopentenyl-N-methyl-2,4-quinoldione (1), maculine (2) and 3'-methoxygraveoline (3), (E)-N-isobutyl-3-methoxy-4,5-methylenedioxicinnamoyl amide (4), the flavones gardenine B (5) and nevadensin (6), and the sesquiterpene intermediol (7). Structure elucidation was based on the analysis of their spectrometric data (uni- and bidimensional ¹H and 13C NMR, MS and IR) and comparison with literature data. Compounds 3-7 are being reported as constituents of Esenbeckia species for the first time. |
