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).

- * 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.
Ruiz and Pav, the second largest genus of the Piperaceae, has over the years shown potential biological activities. In this sense, the present work aimed to carry out a seasonal and circadian study on the chemical composition of essential oils and aromas, as well as to evaluate the preliminary toxicity in Leach and carry out an in silico study on the interaction mechanism. The chemical composition was characterized by gas chromatography (GC/MS and GC-FID).
