Abstract

TEREZAN, Ana Paula et al. Activities of extracts and compounds from Spiranthera odoratissima St. Hil. (Rutaceae) in leaf-cutting ants and their symbiotic fungus. J. Braz. Chem. Soc. [online]. 2010, vol.21, n.5, pp. 882-886. ISSN 0103-5053.  http://dx.doi.org/10.1590/S0103-50532010000500016.

O estudo dos extratos dos galhos da planta Spiranthera odoratissima St. Hil. (Rutaceae) levou ao isolamento de alcalóides furoquinolínicos (dictamina, γ-fagarina e esquimianina) e 2-arilquinolin-4-ona (2-fenil-1-metilquinolin-4-ona) e limonóides (ácido limonéxico e limonina). Os compostos 2-fenil-1-metilquinolin-4-ona e ácido limonéxico foram isolados pela primeira vez no gênero Spiranthera. Os alcalóides furoquinolínicos, 2-arilquinolin-4-ona e os limonóides mostraram atividade inseticida e/ou fungicida no ninho da formiga Atta sexdens rubropilosa.

Keywords : Spiranthera odoratissima; furoquinoline alkaloids; limonoids; Atta sexdens rubropilosa; Leucoagaricus gongylophorus.
