“…Baccharis has also been demonstrated to be able to express a wide phytochemistry diversity (1)(2)(3)(4)(5), meaning the evolutionary success of the taxon could be attributed to its array of secondary metabolites. In particular, in recent years, the analysis of Baccharis volatile compounds has increased for two main reasons: the search for new key aromas that can be applied in the food and fragrance industries, and improving our understanding of the role of volatile organic compounds in plant metabolism and in ecosystem relationships (6,7). Several papers have reported on the analysis of Baccharis essential oils and volatile extracts from male and female plants (8)(9)(10)(11)(12).…”

Differences in female/male plant metabolism for dioecious species are poorly understood but relevant if the economic exploitation of such resources is the objective. In this work, the composition of Baccharis tridentata Vahl essential oil from the flowering aerial parts of male and female plants was analysed separately by GC-MS (gas chromatography-mass spectrometry; area percentage and internal standard), and CPGC-MS (chiral phase gas chromatography analysis using modified β-cyclodextrin), reporting the enantiomeric distribution of monoterpene hydrocarbons as a genuineness criterion. The results confirmed high qualitative similarities between the essential oils from both genders, but quantitative differences in the main components α-pinene, β-pinene, limonene and bornyl acetate. Regarding the CPGC-MS analysis of monoterpene hydrocarbons, both sexes presented both enantiomers in the same ratios, which is in contrast to the values reported in the literature for related plants. However, natural bornyl acetate (isolated from B. tridentata essential oil) demonstrated a 100% enantiomeric excess of the levogyre enantiomer, a fact that has chemotaxonomic relevance.

“…Furthermore, both sesquiterpene compounds are not only reported as typical components of many Baccharis essential oils (including B. dracunculifolia and B. microdonta ) [27,47,48] but also of Baccharis extracts, [49] or even identified in the volatile fraction obtained through SPME from fresh leaves of B. dracunculifolia [50] . In this study, the experimental conditions were considered enough to prevent chemical oxidations.…”

Baccharis dracunculifolia DC. and Baccharis microdonta DC. (Asteraceae) are woody species morphologically similar growing in Uruguay, where not taxonomists people often confuse them in field conditions. As the essential oil of B. dracunculifolia (‘vassoura’ oil) is highly prized by the flavor and fragrance industry, the correct differentiation of the two species is a key factor in exploiting them profitably and reasonably. To differentiate both Baccharis species, in this work their volatile expression profiles were studied as an alternative tool to determine authenticity and quality. Volatile organic compounds (VOCs) were monthly extracted during an entire year from aerial parts of wild populations by simultaneous distillation extraction (SDE), and studied by gas chromatography/mass spectrometry (GC/MS; identification) and conventional gas chromatography (GC‐FID; component abundances determination). Enantioselective gas chromatography/mass spectrometry (Es‐GC/MS) was applied in the search of parameters able to ensure genuineness of each species extract. Qualitative VOCs profiles were found to be similar for both species, being β‐pinene, limonene, spathulenol, caryophyllene oxide, and viridiflorol the main components. However, the abundance of those VOCs were two to ten times higher in B. dracunculifolia than in B. microdonta during the year of study. These Baccharis spp. showed species‐specific patterns of VOCs expression according to the seasonality, and interestingly, oxygenated compounds (trans‐pinocarveol and myrtenal) increased their abundances at full‐flowering stages. The enantiomeric distribution of selected monoterpenes (α‐ and β‐pinenes, limonene, linalool, terpinen‐4‐ol, and α‐terpineol) presented differential values for both Baccharis spp., meaning that Es‐GC might be a useful tool for differentiating chemically both species in Uruguay for genuineness determination purposes.

“…Monoterpenoids and sesquiterpenoids are frequently found in the EOs of Baccharis [ 3 , 30 ]. Sesquiterpenoids seemed to be more abundant in the majority of the species [ 3 , 6 , 7 , 16 , 22 , 30 , 31 , 32 , 33 ]. However, the EO of some species contained more monoterpenoids than sesquiterpenoids, such as in B. obovata [ 21 ], B. schultzii , B. regnelli Sch.…”

Essential Oils of Five Baccharis Species: Investigations on the Chemical Composition and Biological Activities

This paper provides a comparative account of the essential oil chemical composition and biological activities of five Brazilian species of Baccharis (Asteraceae), namely B. microdonta, B. pauciflosculosa, B. punctulata, B. reticularioides, and B. sphenophylla. The chemical compositions of three species (B. pauciflosculosa, B. reticularioides, and B. sphenophylla) are reported for the first time. Analyses by GC/MS showed notable differences in the essential oil compositions of the five species. α-Pinene was observed in the highest concentration (24.50%) in B. reticularioides. Other major compounds included α-bisabolol (23.63%) in B. punctulata, spathulenol (24.74%) and kongol (22.22%) in B. microdonta, β-pinene (18.33%) and limonene (18.77%) in B. pauciflosculosa, and β-pinene (15.24%), limonene (14.33%), and spathulenol (13.15%) in B. sphenophylla. In vitro analyses for antimalarial, antitrypanosomal, and insecticidal activities were conducted for all of the species. B. microdonta and B. reticularioides showed good antitrypanosomal activities; B. sphenophylla showed insecticidal activities in fumigation bioassay against bed bugs; and B. pauciflosculosa, B. reticularioides, and B. sphenophylla exhibited moderate antimalarial activities. B. microdonta and B. punctulata showed cytotoxicity. The leaves and stems of all five species showed glandular trichomes and ducts as secretory structures. DNA barcoding successfully determined the main DNA sequences of the investigated species and enabled authenticating them.
