Acaricidal and insecticidal activity of essential oils obtained from the aerial parts of three Mexican Bursera species.

In search of new sustainable biopesticides, we determined the phytochemical profiles, acaricidal and insecticidal properties of EOs distilled from the aerial parts of three Mexican Bursera species. Results were obtained by GC-MS analysis and three different bioassays, indicating that the EO of Bursera glabrifolia exhibited high relative abundancies of α-pinene, β-myrcene, and α-phellandrene, as well as promising pesticidal activity against Spodoptera littoralis larvae (LD = 32.4, 107.

Central nervous system activity of a Tabernaemontana arborea alkaloid extract involves serotonergic and opioidergic neurotransmission in murine models.

Tabernaemontana arborea (Apocynaceae) is a Mexican tree species known to contain ibogan type alkaloids. This study aimed at determining central nervous system-related activities of an alkaloid extract obtained from the root bark of T. arborea.

Inhibitory effects of methanolic extracts from the stem barks of ten Mexican Jacq. ex L. species on the activity of α-amylase and acetylcholinesterase from .

Methanolic stem bark extracts from ten Mexican Jacq. ex L. species were evaluated with regard to their inhibitory activity against two -derived enzymes.

Potent Anti-amoebic Effects of Ibogaine, Voacangine and the Root Bark Alkaloid Fraction of Tabernaemontana arborea.

Plants of species have several pharmacological activities including antimicrobial effects. Amoebiasis continues to be a public health problem, with increasing evidence of resistance to metronidazole. In this study, we assessed the effect of the alkaloid fraction of root bark and the alkaloids ibogaine and voacangine on the viability and infectivity of trophozoites.

Tabernaemontana arborea and ibogaine induce paroxysmal EEG activity in freely moving mice: Involvement of serotonin 5-HT receptors.

Several Apocynaceae species, most notably Tabernanthe iboga, Voacanga africana and many Tabernaemontana species, produce ibogan-type alkaloids. Although a large amount of information exists about the Tabernaemontana genus, knowledge concerning chemistry and biological activity remains lacking for several species, especially related to their effects on the central nervous system (CNS). The aim of this study was to evaluate the effect of Tabernaemontana arborea Rose ex J.
