| Genipa americana L. has a diversity of secondary metabolites, including iridoids, phenolic compounds, and alkaloids. Pharmacological and biological properties have also been reported. This study has aimed to evaluate the chemical composition of the essential oil (EO) obtained from the leaves of G. americana and its bioactivity against Aceria guerreronis Keifer (Acari: Eriophyidae), a serious pest of coconut production areas worldwide. EO from the leaves was extracted and analyzed by Gas Chromatography-Mass Spectrometry and flame ionization detection (GC-MS/FID). For the bioassays, the adult coconut mites were subjected to increasing concentrations of EO. The analyses showed a predominance of sesquiterpenes, followed by monoterpenes, aldehydes, and fatty... |

| Monoterpenes are a highly diverse group of chemical scents that originate from plant secondary metabolic processes, one purpose of which is to serve as a defense against herbivores. Plant-derived monoterpenes pro- duced from Lamiaceae species have demonstrated acaricidal activity against pest mites and ticks. However, the mechanism by which these compounds carry out the demise of this group of arachnids is poorly understood. Here, we review the chemistry and bioactivity of these promising compounds and subsequently assess their potential toxicity to mites and ticks through measurement of their docking ability to amino acid residues of the binding pocket of Drosophila melanogaster acetylcholinesterase (AChE). We identified 27 monoterpenes of the Lamiaceae... |

| Sesquiterpenes (SS) are secondary metabolites formed by the bonding of 3 isoprene (C5) units. They play an important role in the defense and signaling of plants to adapt to the environment, face stress, and communicate with the outside world, and their evolutionary history is closely related to their physiological functions. This review considers their presence and extensively summarizes the 156 sesquiterpenes identified in Vitex taxa, emphasizing those with higher concentrations and frequency among species and correlating with the insecticidal activities and defensive responses reported in the literature. In addition, we classify the SS based on their chemical structures and addresses cyclization in biosynthetic origin. Most relevant sesquiterpenes of the... |
