The aim of this study was to investigate the chemical constituents of Lindera erythrocarpa essential oil (LEO) by gas chromatography-mass spectrometry and evaluate their inhibitory effect on the expression of pro-inflammatory mediators in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. Fifteen compounds, accounting for 63.7 % of the composition of LEO, were identified. The main compounds we...

Abstract Tea black tussock moth, Dasychira baibarana (Matsumura) (Lepidoptera: Lymantriidae), is a devastating pest species of the tea plant in China. Here, we evaluated responses D. to volatiles using gas chromatography coupled electroantennographic detection (GC–EAD), eleclectroantennography (EAG), and Y-tube olfactometer. In total, 11 18 analyzed compounds elicited GC–EAD from test insects. ...

The possibility to utilize the antibacterial and antibiofilm potential of essential oils (EOs) in dentistry is recognized best seen design EO-based mouthwashes. up-to-date results, obtained with most commonly used formulation being consisted thymol, eucalyptol, menthol, methyl salicylate (Listerine), proved its efficacy against plaque gingival inflammation. However, novel alcohol-free products ...

Dentre a diversidade de espécies plantas alimentícias não convencionais (PANC), Pereskia aculeata Miller, conhecida popularmente como ora-pro-nóbis (OPN), está sendo consumida cada vez mais no Brasil. O objetivo deste estudo foi avaliar capacidade antioxidante e composição das frações volátil flores frutos OPN. A fração isolada por hidrodestilação extração em fase sólida caracterizada CG/EM CG/...

O gênero Psidium é pertencente à família Myrtaceae e compreende importantes espécies botânicas, destacando-se a goiabeira (Psidium guajava L.). óleo essencial (OE) desta espécie já conduziu diversos trabalhos científicos devido sua composição química propriedades farmacológicas, ação antifúngica atividades antimicrobianas. Neste trabalho, duas variedades de Psidium, var. pomifera (Paluma) pyrif...

Objective(s): Development of a nanobiosystem by using plant essential oils with green synthesized silver nanoparticles that present synergistic antibacterial activity for overcoming antibiotic resistance in pathogenic bacteria. Material and Methods: Essential oils (EOs) of Kelussia odoratissima and Teucrium polium extracted by hydrodistillation were analyzed by gas chromatography-mass spectrome...
