The intensive use of antibiotics in aquaculture has resulted increased resistance among fish pathogens, and this situation led researchers to investigate the antibacterial properties natural resources. present study focused on an essential oil isolated from leaves Eucalyptus camaldulensis as a potential that could be used against Aeromonas caviae. Eighteen compounds were identified oil, represe...

The species of the Lamiaceae family produce essential oils in glandular trichomes, leaf surfaces, and inflorescences, can also many secondary compounds, which indicates great potential for study. aim this paper was to describe chemical composition biological, antioxidant, antimicrobial, antitumor activities oil Cantinoa althaeifolia first time. obtained from leaves by hydrodistillation analyzed...

The chemical composition of the essential oils of flower at the pre-flowering, full-flowering and post-flowering stage of A. annua was analyzed by GC and GC/MS and sixty-two components were identified. The main compounds in the pre-flowering oil were β-myrcene (37.71%), 1, 8-cineole (16.11%) and camphor (14.97%). The full-flowering oil contained predominantly caryophyllene (19.4%), germacrene D...

The biodiversity found in Brazilian’s ecosystems brings the possibility of discovering new natural products with wide application potentials. However, knowing their availability and chemical composition is crucial. Thus, aim this study was to evaluate extraction yield, antioxidant activity essential oil from fresh leaves Calyptranthes concinna DC., a native species Myrtaceae occurring Brazilian...

Background: The biotechnological potential of medicinal plants from Brazilian Caatinga and the Atlantic Forest has not been extensively studied. Thus, screening programs are important in prospecting for compounds for developing new drugs. The purpose of this study was to determine the chemical composition and to evaluate the anti-Candida activity of essential oils from leaves of Hymenaea courba...

The screening of several Chinese medicinal plants for insecticidal principles showed that essential oil of Rhododendron anthopogonoides flowering aerial parts possessed significant toxicity against maize weevils, Sitophilus zeamais. A total of 37 components were identified in the essential oil and the main constituents of the essential oil were 4-phenyl-2-butanone (27.22%), nerolidol (8.08%), 1...

Biological, and particularly antimicrobial, activities have been demonstrated for the essential oil of propolis samples worlwide, yet their mutagenic effects remain unknown. To correlate antimicrobial effects with mutagenic risks, the present study evaluated the antifungal and antibacterial activities of the essential oil obtained from brown propolis collected from the Cerrado biome in Midwest ...

In this study, tarragon (Artemisia dracunculus L.) the amount of antioxidants and phenolic substances water-based extracts in various concentrations (25g/L, 50g/L, 100g/L) with aroma components plant was determined. Various food pathogens (Escherichia coli ATCC 25922, Salmonella enterica 13076, Listeria monocytogenes 43251) bacterial strains ((Gram-negative (Vibrio harveyi (KF443058), Vibrio vu...
