This research assessed the fumigant activity of essential oil from Piper sancti-felicis Trel and five its components on Tribolium castaneum (Herbst) biological model. Hydrodistillation was used for extraction oil, with separation identification compounds through gas chromatography coupled to mass spectrometry (GC-MS). The evaluated dispersion T. castaneum. majority found in EO were b-nerolidol ...

Abstract Enzymes empower chemical industries and are the keystone for metabolic engineering. For example, linalool synthases indispensable biosynthesis of linalool, an important fragrance used in 60–80% cosmetic personal care products. However, plant have low activities while expressed microbes. Aided by bioinformatics analysis, four linalool/nerolidol (LNSs) from various Agaricomycetes were ac...

In this study, it was aimed to determinate beneficial effects of Nerolidol (NLR) against reproductive toxicity caused by Thioacetamide (TAA). Male, 3-4-months-old, rats (n=32) were divided into four groups. Group-1 was kept as control and given corn oil as carrier. Group-2 received TAA (200 mg/kg, intraperitoneal (i.p.), two times per week) for 3 weeks, in group-3; NRL was orally administered a...

The essential oil (EO) from leaves of Annona neosalicifolia H. Rainer (Annonaceae) obtained two chemotypes in the southern Brazilian Atlantic Rainforest was analysed both by GC-FID and GC-MS. Forty compounds were identified, accounting for 95.9 to 99.5% total each sample. VOs characterized predominance sesquiterpenes all samples, being main bicyclogermacrene (13.9-41.8%) beta-caryophyllene (9.3...

The present study aimed to evaluate possible variations in the chemical composition and antimicrobial activity of essential oils extracted from Piper marginatum leaves obtained by hydrodistillation at pH4, pH7, pH10. When compared, profiles three were different. A reduction major phenylpropanoids Z-asarone, dillapiole, E-asarone was observed for samples pH4-EO pH10-EO as compared sample pH7- EO...

The essential oils (EOs) of Telekia speciosa, a perennial plant native to southeastern Europe and Asia Minor, were analyzed for their composition biological properties. T. speciosa is an invasive in Poland; however, its beauty prompts gardeners cultivate the plants. serves as valuable source nectar pollen honey bees. Our results revealed more than 150 compounds flower, leaf, root EOs. Major con...
