“…These components could increase the concentration of lipidic peroxides such as hydroxyl, alkoxyl, and alkoperoxyl radicals, which leads to cell death. According to Sharma and Tripathi (2006), the EOs would act on the hypha of the mycelium, provoking exit of components from the cytoplasm, the loss of rigidity, and integrity of the hypha cell wall, resulting in its collapse and death of the mycelium.…”

Context: Psidium cattleianum Sabine (Myrtacea) is rich in vitamin C and phenolic compounds, including epicatechin and gallic acid as the main components. Objective: To evaluate the antifungal and antioxidant capacity in vitro of the essential oil of araçá (EOA). The acute toxicity of the EOA also was evaluated in mice. Materials and methods: The leaves of the P. cattleianum were extracted by steam distillation. The antioxidant capacity was evaluated by in vitro tests [1,1-diphenyl-2-picryl-hydrazyl (DPPH), 2,2-azinobis(3-ethylbenzothiazoline-6-sulfonate) (ABTS), ferric ion reducing antioxidant power (FRAP), linoleic acid oxidation, thiobarbituric acid reactive species (TBARS)], and ex vivo analysis [TBARS, d-aminulevunilate dehydratase (d-Ala-D) and catalase activity, non-protein thiols (NPSH), and ascorbic acid levels]. The toxicity was studied in mice by a single oral administration of EOA; and the antifungal activity was performed with five strains of fungi. Results: The EOA exhibited antioxidant activity in the FRAP assay and reduced lipid peroxidation in the cortex (I max ¼ 32.90 ± 2.62%), hippocampus (IC 50 ¼ 48.00 ± 3.00 mg/ml and I max ¼ 32.90 ± 2.62%), and cerebellum (I max ¼ 45.40 ± 14.04%) of mice. Acute administration of the EOA by the oral route did not cause toxicological effects in mice (LD 50 4500 mg/ml). The EOA also showed antifungal activity through of the determination minimum inhibitory concentration (MIC) values ranging from 41.67 ± 18.04 to 166.70 ± 72.17 mg/ml for tested strains. Conclusion:The results of present study indicate that EOA possess antioxidant properties, antifungal and not cause toxicity at tested doses.

“…Previous antifungal studies have indicated that VA assay is more effective than the PF method. The volatile fractions of Rosmarinus officinalis and Eucalyptus globulus strongly inhibited the mycelial growth of all fungi tested (Survilienė et al, 2009).A vapor activity assay of Citrus sinensis essential oil showed that the oil was fungicidal for Penicillium expansum, Ulocladium chartarum and Alternaria mali from apples (Sharma and Tripathi, 2006).…”

Analysis of essential oils obtained from the seeds (SEO) and leaves (LEO) of Foeniculum vulgareMill cultivated in southeast of Morocco revealed that trans-anethole was the major constituent (54.67% of seed oil and 50.60% in leaf oil), followed by estragol (35.33% of seed oil and 30.15% in leaf oil). Other components present in leaf oil included fenchone, linalool and α-pinene, while seed oil contained fenchone, limonene and γ-terpinen. Besides, minor constituents like camphene, camphor, myrcene, pahllandrene, fenchyl acetate and β-bisabolene were obtained from seeds and leaves. The essential oils of the seeds and leaves of Foeniculum vulgare were assayed for their antifungal activity by poison food (PF) technique and the volatile activity assay (VA) against five agricultural pathogenic fungi. The results indicated that the essential oil of Foeniculum vulgare inhibited the mycelial growth of all fungal strains tested. VA assay of essential oil was consistently found to be more effective than PF technique. The mycelium growth was completely inhibited by LEO on Alternaria sp., Fusarium oxysporum f. sp. albedinis and Aspergillus brasiliensis at 0.25 µl mL -1 air. Rhizopus stoloniferawas the most sensitive with a minimal inhibitory concentration (MIC) = 0.25 µl mL -1 air.

“…Th e orange peel, frequently discarded aft er juice extraction, is rich in essential oil. Essential oil of several species is able to inhibit the germination and growth of other species (Duke et al 2002), and the orange peel essential oil seems to be highly bioactive (Sharma & Tripathi 2006, Ali et al 2007, Tsai 2008. In preliminary assays, we detected strong inhibitory eff ects of orange peel essential oil on the germination and initial growth of lettuce (Lactuca sativa L.).…”

Allelopathic eff ects of orange (Citrus sinensis L.) peel essential oil RESUMO (Efeitos alelopáticos do óleo essencial da casca da laranja (Citrus sinensis L.)). Plantas daninhas são o principal problema da agricultura no mundo, causando anualmente um prejuízo de U$95 bilhões. A principal forma de combate às plantas daninhas são os herbicidas sintéticos. Entretanto, o uso continuado desses produtos encarece a produção, reduz a qualidade dos alimentos, deixa resíduos tóxicos no ambiente e ameaça a saúde humana e animal. Existe assim, uma demanda por técnicas menos agressivas de controle. O uso de compostos alelopáticos de descartes de culturas para esse fi m é uma alternativa. A laranja é uma das maiores culturas do mundo, e gera grandes quantidades de resíduos. Existem evidências da bioatividade no óleo essencial da casca da laranja. Nesse trabalho, nosso objetivo foi verifi car a existência de propriedades alelopáticas desse óleo. Para isto, extraímos o óleo por arraste de vapor de água utilizando o aparelho de Clevenger, e colocamos os produtos volatilizáveis do óleo essencial em contato com plântulas de Euphorbia heterophylla L. e Ipomoea grandifolia (Dammer) O'Donell. O resultado foi inibição tanto quantitativa quanto qualitativa das plântulas Palavras-chave: agricultura orgânica, alelopatia, controle de pragas, descartes de cultivos, Limoneno, plantas invasoras de culturas Jose Pedro Nepomuceno Ribeiro 1,2 and Maria Inês Salgueiro Lima 1 ABSTRACT (Allelopathic eff ects of orange (Citrus sinensis L.) peel essential oil). Crop weeds are the main problem in agriculture, causing a worldwide annual loss of about US$95 billion. Th e principal method for control is the use of synthetic herbicides. Th e continued use of these products increases crop costs, reduces crop quality, and leaves toxic residues in the environment, which are a threat to human and livestock health. Th erefore, there is a demand for environmentally friendly methods of weed control. Th e use of allelopathic compounds from crop residues is an alternative. Orange is one of the biggest crops in the world, and its cultivation generates large amounts of residues. Th ere is strong evidence of bioactivity in orange peel essential oil. Th erefore, the objective in this work was to verify the allelopathic proprieties of this oil. We extracted the oil from the peels of recently discarded oranges using water vapor fl ow with a Clevenger extractor, and tested it against the growth of Euphorbia heterophylla L. and Ipomoea grandifolia (Dammer) O'Donell seedlings when placed in contact with the oil vapor. Th e results were both quantitative and qualitative in the inhibition of the seedlings.
