“…Citronellol (8) is a monoterpene found in some plants used in popular medicine with antihypertensive agents, including Cymbopogon citratus (Abegaz et al, 1983), Cymbopogon winterianus (Quintans-Júnior et al, 2008), and Lippia alba (Tavares et al, 2005). Bastos et al (2010) and showed that citronellol, administered intravenously, produced hypotension and tachycardia in conscious rats.…”

Abstract:The monoterpenes are secondary metabolites of plants. They have various pharmacological properties including antifungal, antibacterial, antioxidant, anticancer, anti-spasmodic, hypotensive, and vasorelaxant. The purpose of this research was to review the cardiovascular effects of monoterpenes. The data in this resarch were collected using the Internet portals Pubmed, Scopus, and ISI Web of Knowledge between the years 1987 and 2010. In the study 33 monoterpenes were included, which were related to each of the thirteen individual words: artery, cardiovascular, heart, myocyte, vasorelaxant, vessel, hypotension, hypotensive, cardiomyocyte, ventricular, vasodilatory, aorta, and aortic. The research utilized 22 articles published mainly in the journals Phytomedicine, Fundamental Clinical Pharmacology, Planta Medica, Life Science, European Journal of Pharmacology, and Brazilian Journal of Medical and Biological Research. Of the 33 monoterpenes studied surveyed, sixteen of them had already been studied for their effects on the cardiovascular system: carvacrol, citronellol, p-cymene, eucalyptol (1,8-cineole), linalool, menthol, myrtenal, myrtenol, α-pinene, rotundifolone (piperitenone oxide), sobrerol, thymol, α-limonene, α-terpinen-4-ol, α-terpineol, and perillyl alcohol. The main effects observed were vasorelaxation, decreased heart rate and blood pressure. This review showed that the monoterpenes may be considered promising agents for prevention or treatment of diseases of the cardiovascular system.

“…This can be attributed to the amount of metabolites present in the leaves, since different phenological stages of plants influence the amount and the dynamic of secondary metabolites that are present in them (GobboNeto and Lopes, 2007). Tavares et al (2005) analyzed the essential oil of three chemo types of Lippia alba and found an increase in the percentage of limonene during the flowering season, however the percentage of citral, carvone and linalool has slightly decreased during the reproductive phase. Németh et al (1993) have studied wild specimens of Achillea crithmifolia under different environmental conditions and developmental stages; they found that the rate of camphor in the essential oil decreased as the plants have advanced in their phenological stages.…”

The fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) is a polyphagous species which attacks many economically important crops in several countries. This insect is an important pest of corn, and currently the most widely used control method is chemical. In order to minimize environmental impacts, other forms of control have been tried, and accordingly, the investigation of plants with insecticidal effects becomes relevant. Thus the present study was conducted in order to evaluate the effect of the ethanolic extract of Euphorbia pulcherrima (poinsettia) leaves in fall armyworm biology. Extracts were prepared from leaves of the plant E. pulcherrima collected at different phenological stages (vegetative and reproductive), oven dried, crushed and then solubilized in ethanol, yielding the ethanol extract. The extracts were set aside in 0.5 and 1% concentrations for each phenological stage of the plant, incorporated into an artificial diet and offered to the larvae of S. frugiperda. The extract of vegetative and reproductive phase of E. pulcherrima leaves in concentrations of 0.5 and 1%, has showed that it affected mortality in the larvae, increasing the larval period and reducing the weight of larvae and pupae and viability of the eggs of the caterpillars. Ethanolic extract of E. pulcherrima leaves in the reproductive phase of the plant is effective to reduce the S. frugiperda population.

“…A composição do óleo essencial de L. alba apresenta variação quantitativa e qualitativa, levando à separação em quimiotipos (Julião et al, 2003;Tavares et al, 2005 xylophilus (Park et al, 2007). De acordo com Matos (1996), o quimiotipo I é produtor de óleos essenciais ricos em mirceno, neural e geranial.…”

RESUMO: O controle de fitonematóides é uma tarefa difícil. A alta infestação de nematoides no solo obriga os produtores a usarem doses mais elevadas de nematicidas, ou ainda, a aumentarem a freqüência das aplicações, geralmente no solo, ocasionando maior potencial de dano ao homem e ao ambiente. Além disso, nematicidas convencionais vêm sofrendo grandes restrições de uso em muitos países. Desse modo, a busca de novas medidas de controle de fitonematóides é uma prioridade da agricultura sustentável. Desta forma, objetivou-se estudar o efeito de óleos essenciais de Lippia Alba, na mortalidade de juvenis pré-parasitas do segundo estádio de Meloidogyne incognita. O ensaio foi montado em delineamento inteiramente casualizado, com 4 repetições, em esquema fatorial 3×4 (3 quimiotipos x 4 concentrações) empregando-se três diferentes quimiotipos de L. Alba (I, II, III) nas concentrações de 0, 100, 500 e 1000 ppm, coletados em diferentes horas do dia (7, 9, 13, 16 e 19h ABSTRACT: Antagonist activity of the essential oil Lippia alba (Mill.) N. E. Brown (Verbenaceae) on Meloidogyne incognita (Kofoid & White) Chitwood. The control of nematodes is difficult. The high infestation of nematodes in the soil requires the producers use higher doses of nematicides, increasing the frequency of applications, usually in soil, causing negative effects to humans and the environment. Furthermore, conventional nematicides have suffered great use restrictions in many countries. Thus, the search for new measures to control nematodes is a priority of sustainable agriculture. Thus, the objective of this study was available the effect of essential oils from Lippia Alba against Meloidogyne incognita. The experiment was conducted in a completely randomized design with four replications in a factorial 3x4 (3 chemotypes and 4 concentrations) using three different chemotypes of L. Alba (I, II, III) at concentrations of 0, 100, 500 and 1000 ppm, collected in different times of day (7 AM, 9 AM, 1 PM, 4 PM e 7 PM). The data collected (% mortality) were subjected to analysis of variance and mean values were compared using the Tukey test. It was able to conclude that L. alba contains in its essential oil, compounds with significant effects on mortality of M. incognita. Thus, it is important to note that the greatest nematicide effect of essential oil of L. alba suggests the possibility of its use to control M. incognita.
