The present work involves a systematic review of the chemical composition and biological effects of essential oils from the Annonaceae species collected in Brazil from 2011 to 2021. Annonaceae is one of the most important botanical families in Brazil, as some species have economic value in the market as local and international fruit. In addition, the species have useful applications in several areas-for instance, as raw materials for use in cosmetics and perfumery and as medicinal plants. In folk medicine, species such as

To study the chemical constituents, antimicrobial activity and antitumor activity of the essential oil from Zanthoxylum avicennae.. The essential oil from the leaves of Zanthoxylum avicennae was extracted by steam distillation. The components of the essential oil were separated and identified by GC-MS.. 72 components were identified and accounted for 98.15% of the all peak area. The essential oil exhibited strong antitumor activity against K-562 human tumor cell lines with IC50 of 1.76 microg/mL. It also exhibited moderate antimicrobial activity against three bacteria.. The essential oil of Zanthoxylum avicennae contains various active constituents. This result provides scientific reference for the pharmacological further research of Zanthoxylum avicennae.

The essential oils of Anthospermum emirnense Baker and Anthospermum perrieri Homolle ex Puff, obtained by hydrodistillation in 0.03 and 0.02% yield, respectively, were analyzed by GC/MS. In both cases, the major constituents consisted of sesquiterpene hydrocarbons and oxygenated sesquiterpenes. The two species showed an important qualitative similarity, with 40 compounds common to A. emirnense and A. perrieri, including β-elemene, trans-β-caryophyllene, caryophyllene oxide, and τ-cadinol, which were major components in both cases. When tested for antimicrobial activity, both essential oils showed similar profiles and exhibited interesting minimal-inhibitory-concentration (MIC) values towards Bacillus subtilis, Chryseobacterium indologenes, Flavimonas oryzihabitans, and Yersinia enterocolitica.
