Essential oil of Baccharis cordobensis Heering

Abstract

The essential oil of the aerial parts of Baccharis cordobensis was examined by GC and GC–MS. The major constituents were trans‐nerolidol (15.8%), T‐cadinol (14.7%) and cubenol (8.8%). Copyright © 2000 John Wiley & Sons, Ltd.

“…The remaining structures were identified by comparison with library information on MS and RI data. In general, earlier papers (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23) showed that, although the main component may vary, the sesquiterpene fraction is usually the dominant one. Likewise, the sesquiterpene fraction constituted the major part of the oil from B. elaeoides, where as the oil of B. magellanica was mainly constituted of the monoterpenes 4-hydroxyacetophenone and massioa lactone.…”

“…Several of the terpenoids identified in this study have previously been reported from other Baccharis species. As they are widely distributed over the subsections, no taxonomic relationship can be established at the generic level (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)35,36). Studies on additional pharmacological properties of the teas and species are currently in progress.…”

“…The genus Baccharis L. belongs to the family Asteraceae, subfamily Asteroideae and tribe Astereae, comprising of more than 400 species of useful, aromatic and medicinal plants widely distributed in Central and South America. Since the genus Baccharis is widely used in traditional medicine (1), several pharmacological studies have been performed and Baccharis species are found to be antiviral (2), 18 Simonsen et al…”

“…The main constituents in the four studied species have been reported to be (E)-nerolidol, (Z)-b-ocimene, b-cadinene, bicyclogermacrene, caryophyllene oxide, chromolaenin, cis-a-copaen-8-ol, cubenol, dihydroisochromolaenin, elemol, germacrene D, limonene, myrcene, sabinene, terpinen-4-ol, verboccidentafuran, viridiflorol, acadinol, a-eudesmol, a-muurolol, a-phellandrene, a-pinene, a-thujene, b-caryophyllene, b-pinene and d-cadinene (8,9). These constituents also occur in several other well studied leaf oils from other Baccharis species (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23).…”
