Volatile Constituents from Baccharis spp. L. (Asteraceae): Chemical Support for the Conservation of Threatened Species in Uruguay.

摘要: Chemical bioprospecting is an important tool for generating knowledge regarding local human-threatened floras and conservation management. For Baccharis L. (Asteraceae), several volatile components have been reported Brazil, Argentina, Bolivia, Chile as a result of bioprospection, but not Uruguayan flora, which composed more than 50 native species. In this work, through collection aerial parts different species simultaneous-distillation extraction gas chromatography-mass spectrometry analyses, twelve were studied (B. articulata, B. cultrata, genistifolia, gibertii, gnaphalioides, ochracea, phyteumoides, punctulata, crispa, dracunculifolia, linearifolia subsp. linearifolia, spicata). A detailed analysis the male female composition was conducted last four The profiles gnaphalioides are first time. Because half analyzed in work Uruguay threatened or potentially by human economic activities, importance their natural, sustainable resources highlighted.
