摘要: An investigation of Morinda citrifolia roots afforded a new anthraquinone, 2-ethoxy-1-hydroxyanthraquinone (1), along with five other known anthraquinones: 1-hydroxy-2-methylanthraquinone (2), damnacanthal (3), nordamnacanthal (4), 2-formyl-1-hydroxyanthraquinone (5) and morindone-6-methyl-ether (6). This is the first report on isolation (6) from this plant. The structures these compounds were elucidated based spectroscopic analyses such as NMR, MS IR. Biological evaluation pure all extracts against larvae Aedes aegypti indicated (2) (3) to exhibit promising larvicidal activities.
