The essential oils and aroma derived from the leaves (L), stems (St), and spikes (s) of L. cv. Guajarina were extracted; the essential oils were extracted using hydrodistillation (HD), and steam distillation (SD), and the aroma was obtained by simultaneous distillation and extraction (SDE).

Chemical composition of the essential oils (EOs) from the leaves of five Annonaceae species found in the amazon region was analyzed by Gas chromatography coupled to mass spectrometry. The antifungal activity of theses EOs was tested against Candida albicans, Candida auris, Candida famata, Candida krusei and Candida tropicalis. In addition, an in silico study of the molecular interactions was performed using molecular modeling approaches.

- * Preliminary tests showed significant toxicity against Leach larvae, with mortality rates over 80% at low concentrations, and the antioxidant activity was highest in specific oils extracted from leaves and stems.
- * Molecular modeling suggested possible interactions with acetylcholinesterase, highlighting the potential for these essential oils in future research and applications.
Four species of the genus can be found in Brazil. is a species endemic to India and Brazil. In this paper, we collected six specimens of for evaluation of their volatile chemical profiles.

Article Synopsis
- The essential oils (EOs) of two Annonaceae species, Gsch and Xfru, were extracted through hydrodistillation and analyzed for their chemical composition using gas chromatography-mass spectrometry.
- The EO of Xfru had the highest yield (1.06%), with major components like α-pinene and β-pinene, while Gsch was rich in sesquiterpenes such as spathulenol and caryophyllene oxide.
- The study evaluated herbicidal activity by assessing seed germination and growth in invasive species, revealing that one species was more resistant to Xfru, while another showed greater sensitivity to Gsch; molecular docking suggested strong inhibitory activity of δ-cadinene against a specific protein
