“…In South Korea, conifer species in the plant families Pinaceae (e.g., Pinus koraiensis, Pius densiflora, Larix kaempferi, Abies holophylla) and Cupressaceae (e.g., Chamaecyparis obtusa, Platycladus orientalis, Chamaecyparis pisifera) are widely distributed (Shannon, 1956). However, antibacterial activities of essential oils of these species (Yang et al 2007;Lee et al 2008) were little known as literatures. We therefore investigated the antibacterial activities of essential oils from P. densiflora, L. kaempferi, P. koraiensis and A. holophylla against K. pneumoniae, H. influenzae, S. pyogenes, S. pneumonia, and N. meningitides, which are the bacterial species most often associated with respiratory tract infections (Bauernfeind et al 1999;Corless et al 2001).…”

We extracted essential oils from four species (Pinus densiflora, Larix kaempferi, Pinus koraiensis, and Abies holophylla) in the family Pinaceae to investigate their antibacterial activities against respiratory tract bacteria (Klebsiella pneumoniae, Haemophillus influenzae, Streptococcus pyogenes, Streptococcus pneumonia, and Neisseria meningitides). Among the tested oils, that from A. holophylla was showed strong activity based on disc diffusion and broth medium dilution (minimum inhibitory concentration, MIC) assays. Qualitative analysis of A. holophylla oil was carried out by GC-MS; α -pinene, camphene, β -pinene, 3-carene, limonene, bornyl acetate, borneol, β -caryophyllene, α -caryophyllene, caryophyllene oxide, and α -bisabolol were identified as its major constituents. Fractionation by silica gel chromatography was performed to analyze the active constituents of the crude oil. In particular, one fraction containing caryophyllene oxide as the major constituent showed stronger antibacterial activity than the crude oil of A. holophylla. Growth rates of bacterial strains exposed to fraction D were explored by optical density (OD600) measurements while morphology was examined by optical microscopy observations (× 1000). OD600 of K. pneumoniae decreased from 0.2582 to 0.005 in response to treatment with fraction D at a MIC value of 0.31 μ ℓ /mℓ .

Extração de Chenopodium ambrosioides L. brasileiro revelou um baixo rendimento (0,3%) do óleo essencial (OE), com uma boa atividade contra oito fungos importantes. Visando melhorar a extração de antifúngicos, o extrato hexano foi avaliado. A extração hexânica melhorou o rendimento (1,1%) dos antifúngicos com uma atividade comparável ao OE. As composições químicas dos extratos, bruto e purificado, foram determinadas tentativamente por meio de cromatografia de fase gasosa (índices de retenção de Kováts) e cromatografia de fase gasosa-espectrometria de massas.Hydroextraction of the Brazilian Chenopodium ambrosioides L. produced a very low yield (0.3%) of the essential oil (EO) with a good activity against eight important fungi. Aiming to improve the yield of the antifungals, hexane was evaluated as an extraction solvent. Hexane extraction improved the yield (1.1%) of the antifungals with activity comparable to that of the EO. The chemical compositions of the crude and purified extracts were tentatively determined by gas chromatography (Kováts retention indices) and gas chromatography-mass spectrometry.Keywords: Brazilian Chenopodium ambrosioides L., hexane extract, antifungal activity, chemical composition IntroductionSpecies of Aspergillus, Colletotrichum, and Fusarium are the major causes of post-harvest economic losses of fruit, vegetables and grains in tropical ecosystems. These fungi are presently managed mainly by synthetic fungicides, posing health and environmental hazards. Thus, alternative safer compounds are needed to control these fungi. Although extracts of several edible botanicals are reported to have antifungal activity, 1-7 little work has been done to manage fungal deterioration of stored products by edible plant derived bioactive compounds. [8][9][10] Epazote (Chenopodium ambrosioides L.) is an herb native to South America, cultivated in sub-tropical and sub-temperate regions, mostly for consumption as leafy vegetable and herb. Because of its pungent flavor, it is traditionally used to season beans and other South American dishes. Its extract and essential oil (EO) are known to have medicinal, 11-14 acaricidal 15,16 and insecticidal [17][18][19] properties but there are only few reports on its antifungal properties. [20][21][22][23] Although a low fungal activity of dichloromethane extracts of epazote was reported, 22,23 neither its chemical composition nor the principal fungitoxic component were reported.In our previous study, we obtained satisfactory antifungal activity with the Brazilian C. ambrosioides EO. 21 However, it's very low yield (0.3% based on fresh weight basis) led us to investigate another extraction solvent. Since the EO contained non polar compounds 21 we have evaluated hexane in this study as it is non polar, inexpensive and widely available. In addition, we determined the fungal activity of the hexane extracts (crude and purified) against eight major postharvest deteriorating fungi, identifying its principal fungitoxic compound along with tentative chemical compositions b...

ResumoAs substâncias repelentes ou atraentes das plantas são, principalmente, de natureza terpênica e se apresentam como moléculas de baixo peso molecular e volátil. Essas substâncias, normalmente, são conhecidas como aromáticas e se denominam óleos essenciais, os quais se acumulam em todos os órgãos vegetais. Nos vegetais, os óleos essenciais desenvolvem funções relacionadas com sua volatilidade, agindo na atração de polinizadores, na proteção contra predadores, nos patógenos, na perda de água, no aumento de temperatura e também desempenhando funções ecológicas, especialmente como inibidoras de germinação. Essas características tornam as plantas que os produzem poderosas fontes de agentes biocidas, o que é largamente estudado nos agroecossistemas, principalmente no que concerne às ações bactericida, fungicida e inseticida. Os óleos essenciais têm como principais constituintes os monoterpenos, seguidos pelos sesquiterpenos, além de compostos aromáticos de baixo peso molecular. Sua função específi ca na planta ainda é desconhecida, porém se acredita que, durante o seu desenvolvimento, as plantas superiores sintetizam terpenóides essenciais para o próprio crescimento. Essas substâncias do metabolismo secundário podem agir como inibidores de germinação, proteção contra predadores, atração de polinizadores, entre outras. Entretanto, a avaliação desses compostos com fi nalidades diversas, como, por exemplo, no controle de microrganismos patogênicos de plantas cultivadas ou, ainda, como inseticida ou herbicida natural, é recente, visto que são poucos os trabalhos de pesquisa desenvolvidos e publicados nessa área. Esta revisão em artigo trata das interações dos óleos essenciais de plantas medicinais, silvestres e cultivadas com microrganismos e insetos.Palavras-chave: óleos essenciais, insetos, fungos, bactérias. AbstractThe repelling or attracting plants substances are mainly from terpenic nature and they appear as molecules with less molecular weight and volatile. Usually, these substances are known as aromatic or essential oils, which amass themselves at all herbal organs. In the herbs, essential oils develop functions related to volatility, acting to attract the pollinating, to protect against pathogens predators, in the missing of water, to rise the temperature and also making ecological functions, especially as a germination inhibitor. These features make the plants which produce these aromatics a powerful source of biocidal agents, being steadily studied in agroecosystems, principally because of the bactericidal, fungicidal, and insecticidal activities. The main components are the monoterpenes, followed by sesquiterpenes, besides aromatic compounds with low molecular weight. The specifi c function that essential oils turns out on the plant is still unknown; however, it is supposed that the higher plants synthesize terpenoids which are essential to their growth. These substances of secondary metabolism can act as germination inhibitors, protection against predators, pollinator attractors, among others. However, t...
