Comparative analysis of essential oils of Baccharis L.: a review

Resumo

Baccharis belongs to Asteraceae and has provided valuable biomolecules in the discovery of new natural medicinal products. Baccharis is a rich source of essential oils and many compounds have been identified as a-pinene, b-pinene, limonene, b-caryophyllene, germacrene-D, and spathulenol. This work brought together several papers and compared the essential oil content and chemical constituents of 33 samples of 22 species of Baccharis. Variations can be observed both in the terpene constituents as well as the content of monoterpenes and sesquiterpenes.
