Chemical composition and larvicidal activity of the essential oil of Pimenta dioica leaves

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.

Evaluation of Influencing Factors and Technological Processes for the Production of Orange Essential Oil (<i>Citrus sinensis</i>) on Equipment Semi-industrial Distillation

“…In this study 2006 [27] 2010 [39] 2012 [30] 2019 [1] 2019 [3] 2020 [40] 2020 [41] 2021 [ In addition, this can also be shown that because each geographical region, climatic conditions, farming, and harvesting conditions will greatly affect the quality as well as the content of volatile compounds present in the plants.…”

“…The results show that limonene is still the main compound, although there are many significant changes in some studies. That changes in the study of Kaskoos [1], Gomes et al [41], Atti-Santos et al [20], Smeriglio et al [46], Sreepian et al [47] when the content of the main compound Limonene accounted for less than 50% in the essential oils of lemons. This is the opposite in the essential oils of Citrus paradisi peels and Citrus reticulate peels, the main compounds in these peels all account for high content of over 80%.…”

Eugenol-Rich Essential Oil from Pimenta dioica: In Vitro and In Vivo Potentialities against Leishmania amazonensis

“…A total of 16 previously reported EO-Pd compositions [ 2 , 3 , 6 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 ] in addition to this present work were used for the Hierarchical Cluster Analysis (HCA). The 11 most abundant EO components (myrcene, p -cymene, limonene, 1,8-cineole, linalool, chavicol, eugenol, methyl eugenol, β-caryophyllene, α-humulene, and α-cadinol) were used to establish the chemical relationship between the EO samples using the XLSTAT software, version 2018.1.1.62926 (Addinsoft™, Paris, France).…”

Chemical composition and larvicidal activity of essential oil of the bark of Citrus sinensis (L.) Osbeck

“…Citric compounds, for the most part, consist of limonene [16]. Previous studies show that this compound alone or as a major constituent in plants has larvicidal activity against Aedes aegypti [6,7,17]. Among citrus species with high limonene content, we highlight Citrus sinensis (L.) Osbeck.…”

“…Within this perspective, we highlight larvicides based on extracts or oils distilled from plants. Previous studies have shown the larvicidal activity of some plants [4][5][6][7][8][9], due to high biodegradability, low toxicity to mammals [10,11], impediment of ovoposition, inhibition, growth and reproduction against mosquito species [12,13] and in some cases with greater durability than synthetic products [14,15]. Generally, the biological activity of a plant is attributed to the component in greater quantity, in which case limonene is highlighted.…”
