Abstract

In this study, we investigated the main constituent, the predominant class and biological activity of the essential oil extracted from the leaves of Pimenta dioica and the pattern of the major constituent against larvae in the third stage of Aedes aegypti. For this reason, we extracted the oil by hydrodistillation, identified its components by gas chromatography coupled with mass spectrometry (GC/MS) and calculated the lethal concentration (LC50) of the larvicidal activity using the Reed-Muench method. The results show that the oil consists mainly of eugenol, in which the phenylpropanoid class predominated and the lethal concentration, LC50, was 38.86 μg mL-1at a confidence level of 2.25 μg mL-1, while the eugenol standard presented LC5079.75 μg mL-1at a confidence level of 2.10 μg mL-1. Given the facts, we conclude that the oil is more active than the standard and that it has the potential to replace chemical larvicides.

洋红叶精油的化学成分及杀虫活性研究

本研究研究了洋红叶精油的主要成分、优势类和生物活性，以及主要成分对埃及伊蚊第三期幼虫的作用规律。为此，我们采用水蒸气蒸馏法提取油，气相色谱-质谱联用(GC/MS)法鉴定油中成分，并用Reed-Muench法计算油中杀虫活性的致死浓度(LC50)。结果表明，丁香酚主要成分为苯丙类，致死浓度LC50为38.86 μg mL-1，置信水平为2.25 μg mL-1;丁香酚标准品LC5079.75 μg mL-1，置信水平为2.10 μg mL-1。考虑到这些事实，我们得出结论，这种油比标准油更有活性，它有可能取代化学杀幼虫剂。

期刊介绍： The Boletín Latinoamericano y del Caribe de Plantas Medicinales y Aromáticas (BLACPMA), [Latin American and Caribbean Bulletin of Medicinal and Aromatic Plants]; currently edited by the publishing house MS-Editions, is a bi-monthly international publication that publishes original peerreviewed research in the field of medicinal and aromatic plants, with nearly 20 years of experience. BLACPMA is a scientific journal that publishes two types of articles: Reviews (only in English) and Original Articles (Spanish or English), its main lines of action being agronomy, anthropology and ethnobotany, industrial applications, botany, quality and standardization, ecology and biodiversity, pharmacology, phytochemistry, pharmacognosy, regulatory and legislative aspects. While all areas of medicinal plants are welcome and the experimental approaches used can be broad and interdisciplinary; other areas of research that are not mentioned depend on the Editorial Committee for their acceptance.
