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.

The study of the Spiranthera odoratissima St. Hil (Rutaceae) branches extracts led to the isolation of the furoquinoline (dictamine, γ-fagarine and skimmianine) and 2-arylquinoli-4-one (1-methyl-2-phenylquinolin-4-one) alkaloids and limonoids (limonexic acid and limonin). The compounds 1-methyl-2-phenylquinolin-4-one and limonexic acid were isolated for the first time from the Spiranthera. These furoquinoline and 2-arylquinoli-4-one alkaloids and limonoids showed insecticidal and/or fungicidal activity in the nest of the Atta sexdens rubropilosa.

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