This study investigated the chemical composition, and antimicrobial activity against food-borne pathogens of essential oil isolated from heartwood Calocedrus formosana Taiwan. The oil, by hydrodistillation in a Clevenger-type apparatus, was characterized using GC–FID GC–MS. major constituents were τ-muurolol (16.1%), α-cadinol (11.1%), α-terpineol (10.6%), thymol (8.5%), β-thujaplicin (4.5%). d...

Bioautography has been used as rapid and easy strategy to detect and identify bioactive fractions/molecules in the never before investigated Hedyosmum sprucei Solms (Chloranthaceae) essential oil (EO). The antioxidant activity, performed through DPPH bioautographic assay and spectrophotometric evaluations (IC50 = 230 ± 10 µg/mL), seemed to be mainly due to α-cadinol and α-muurolol. (HP)TLC bioa...

Antimite activity of essential oils and their components obtained from Taiwania cryptomerioides Hayata heartwood against Dermatophagoides pteronyssinus (Trouessart) and Dermatophagoides farinae Hughes was investigated in this study. Results from antimite tests demonstrated that the essential oil extracted from T. cryptomerioides heartwood had miticidal activity against D. pteronyssinus and D. f...

Essential oils from three of the eleven endemic New Zealand species of Pseudopanax, P. arboreus, P. discolor and P. lessonii, were found to have a fairly uniform composition which was different from that of the oils of Raukaua species that were formerly classified in the Pseudopanax genus. Oils of the three Pseudopanax species all contained significant proportions of viridiflorol and a closely ...

Marigold oil is a product of great industrial interest thanks to its wide range medicinal and wound-healing properties. In this work, supercritical carbon dioxide was used recover marigold essential from the hexane solvent extract flowers, floral “concrete”. This starting material mixed with synthetic paraffinic waxes heighten melting point viscosity, thus, improving processability. Supercritic...

in this paper we initiate the study of real group algebras and investigate some of its aspects.let l1 (g) be a group algebra of a locally compact group g,τ :g →g be a group homeomorphismsuch that τ 2 =τοτ = 1, the identity map, and lp (g,τ ) = { f ∈ lp (g) : fοτ = f } ( p ≥ 1) . in thispaper, among other results, we clarify the structure of lp (g,τ ) and characterize amenability ofl1 (g,τ ) and...

Resistance to conventional fungicides causes the poor disease control of agriculture. Natural products from plants have great potential as novel fungicide sources for controlling pathogenic fungi. In this study antipathogenic activity of the leaf essential oil and its constituents from Calocedrus macrolepis var. formosana Florin were evaluated in vitro against six plant pathogenic fungi. Chemic...
