Research paper thumbnail of Investigation of the essential oil from eight species of Baccharis belonging to sect. Caulopterae (Asteraceae, Astereae): a taxonomic approach

Plant Systematics and Evolution, 2005

Essential oils of B. articulata, B. crispa, B. microcephala, Baccharis milleflora, B. myriocephal... more Essential oils of B. articulata, B. crispa, B. microcephala, Baccharis milleflora, B. myriocephala, B. stenocephala, B. trimera and B. usterii, all of sect. Caulopterae, have been analyzed by GC and GC/MS. Despite the morphological similarity among these species, differences in composition of their essential oil obtained by hydrodistillation and hexane extract could be observed. Special attention was given to Baccharis trimera and B. crispa since their differentiation during early stages is not possible due to the absence of synflorescences. Carquejyl acetate is suggested as a marker for Baccharis trimera, and a fast method of detection of this compound is given.

In vitro systems were used to assess the antioxidant properties of the extracts. Isolated rat hearts were treated with both extracts before ischemia and myocardial function was assessed. Thiobarbituric acid reactive substances (TBARS) concentration and reduced glutathione (GSH) were also measured. B extract showed higher total phenols and ascorbic acid contents and a higher scavenging activity of peroxynitrite and ferric reducing antioxidant power (FRAP) than P extract. Postischemic systolic and diastolic functions were improved after B and P treatment. Both extracts decreased TBARS and preserved GSH content.
