CHEMICAL COMPOSITION AND OVICIDA ACTIVITY OF THE ESSENTIAL OIL OF CROTON ARGYROPHYLLUS (EUPHORBIACEAE) LEAVES ABOUT AEDES AEGYPTI (DIPTERA: CULICIDAE

The control of Aedes aegypti, which transmits several arboviruses of importance to public health, has as strategies the use of synthetic insecticides, integrated with environmental control. Its control is mainly directed to the larvae and adult phases. The egg phase is difficult to control, as it has great resistance to environmental conditions. The objective of this work was to evaluate the ovicidal potential of the essential oil obtained from the leaves of Croton argyrophyllus, on Aedes aegypti, as well as to determine the moisture content, the yield, and its chemical composition. The eggs were exposed to the aqueous solution of the essential oil in 10% Tween 80, in the concentration of 12 mg mL-1, for a period of 15, 30, 60, and 120 minutes. Subsequently, the eggs were washed and, after 180 hours of observation, the feed was added. The analysis of the chemical composition of the essential oil was performed by Gas Chromatography coupled to Mass Spectrometry. It was found that up to 180 hours of observation, the highest percentage of larval hatching occurred in eggs exposed to essential oil for 15 min (30%) and the lowest percentage in eggs exposed for 120 min ( less than 10%). After 180 hours, there was an increase in hatching in all treatments. The moisture content was 58.69%, the oil yield was 0.35%, and the main chemical constituents found were bicyclogermacrene and b-cariophylene. It was observed that the essential oil of Croton argyrophyllus, at the concentration evaluated, affects the hatching of Aedes aegypti larvae only in the absence of food.

ABSTRACT: Campomanesia adamantium is a native fruit species of the Cerrado and is used in food and medicines and as bee pasture. The chemical composition of essential oils obtained from plants of the same species have varying constituent proportions due to the influence of extractive factors, environmental, genetic and ontogenetic. This study aimed to identify the influence of hydrodistillation time on the content and chemical composition of essential oil extracted from the leaves of C. adamantium . Treatments consisted of five extraction times (1, 2, 3, 4, and 5h) using Clevenger with five replications in a completely randomized design. It was observed that after two hours of hydrodistillation, the essential oil content remains constant. Regarding the chemical constituents of essential oil, variation of the proportions of the compounds tested occurred at all hydrodistillation times. The compounds spathulenol oxygenated sesquiterpenes and caryophyllene oxide were the majority in the five hydrodistillation times.

“Yellow moena” (Nectandra longifolia: Lauraceae) is a fragrant leaves-possessing plant commonly used for timber purposes. Nevertheless, so far, there is not available information about its chemical composition. Thus, in the present work is described the components of the essential oil from N. longifolia leaves. The oil was extracted by steam distillation and analyzed by GC/FID and GC/MS. Twenty eight compounds were therefore identified. The main components were found to be terpinen-4-ol (53.1%), α-terpinene (6.8%), α-phellandrene (4.5%), and β-pinene (3.8%). The chemical composition of essential oil from N. longifolia leaves was consequently in agreement to that of several neotropical Lauraceae plants. In addition, the oil exhibited good antifungal activity against F. oxysporum through dose-dependent mycelial growth inhibition (using amended media and fumigant assays).

Frequent Use

The mosquito Aedes aegypti is an epidemic vector of several diseases such as dengue fever and yellow fever. Several pesticides are used to control the mosquito population. Because of their frequent use, some mosquitoes have developed resistance. In the present study, we evaluated the synergistic mosquito-repellent activity of essential oils from Pelargonium radula, Syzgium aromaticum and Citrus aurantifolia against Aedes aegypti by using Y-tube olfactometer. The oils was subsequently analyzed by using GC–MS. These results clearly reveal that the essential oil of C. aurantifolia served as the most potent repellent agent against Aedes aegypti . The results indicate that three constituents; limonene (19.58%) followed by β–pinene (17.12%), geraniol (13.23%) which comprise a large proportion of the C. aurantifolia are likely responsible for the observed repellent activity.

Herb Species

The restinga is an Atlantic Forest ecosystem characterized by tree, shrub, and herb species that are rich sources of essential oils. In this study, we aim to quantify the essential oil content and determine the chemical constituents of fresh leaves of 14 plant species in a restinga stretch in southern Brazil. Essential oils were obtained by hydrodistillation in a Clevenger-type apparatus and analyzed by gas chromatography coupled to mass spectrometry. Campomanesia reitziana, Cortaderia selloana, and Sophora tomentosa had no essential oils. Total essential oil content ranged from 0.01% (Mikania involucrata) to 1.56% (Varronia curassavica). In total, 60 chemical constituents were identified, representing between 46.2% and 96.5% of the chemical composition of the essential oils. Limonene was the common constituent in all species in which the essential oils were present. The major constituents were ar-curcumene (15.1%) and cis-chrysanthenol (14.2%) in Ambrosia elatior; benzyl benzoate (43.5%) and benzyl salicylate (23.7%) in Aniba firmula; caryophyllene oxide (35.7%) and spathulenol (10.6%) in Austroeupatorium inulaefolium; spathulenol (19.8%) and caryophyllene oxide (14.0%) in Baccharis spicata; caryophyllene oxide (16.3%) in Eugenia astringens; curzerene (30.0%), limonene (13.0%), and germacrone (11.9%) in Eugenia uniflora; caryophyllene oxide (17.1%) and ledol (11.3%) in Lantana camara; caryophyllene oxide (27.7%) and limonene (12.7%) in M. involucrata; 1,8-cineole (19.8%) in Psidium cattleianum; limonene (10.2%) in Schinus terebinthifolius, and allo-aromadendrene (15.2%) in V. curassavica. We expect that our results can assist in selecting species of potential interest for herbal, phytotherapeutic, and cosmetic products.

ABSTRACTThis study evaluated the larvicidal activity of O. majorana essential oil, identified the chemical composition, evaluated the antimicrobial, cytotoxic and antioxidant potential. The larvicidal activity was evaluated against larvae of the third stage of Aedes aegypti, whereas the chemical composition was identified by gas chromatography coupled to mass spectrometer, the antimicrobial activity was carried out against the bacteria Pseudomonas aeruginosa, Escherichia coli and Staphylococcus auereus, the antioxidant activity was evaluated from of 2.2-diphenyl-1-picryl-hydrazila sequestration and Artemia salina cytotoxicity. Regarding to the results, the larvicidal activity showed that O. majorana essential oil caused high mortality in A. aegypti larvae. In the chromatographic analysis, the main component found in O. majorana essential oil was pulegone (57.05%), followed by the other components verbenone (16.92%), trans-p-menthan-2-one (8.57%), iso-menthone (5.58%), piperitone (2.83%), 3-octanol (2.35%) and isopulegol (1.47%). The antimicrobial activity showed that E. coli and P. aeruginosa bacteria were more sensitive to oil than S. aureus, which was resistant at all concentrations. Essential oil did not present antioxidant activity, but it has high cytotoxic activity against A. salina.
