Ethanol-soluble amphiphilic TiO(2) nanoparticles (NPs) of average diameter ∼9 nm were synthesized, and an α-terpineol-based TiO(2) paste was readily prepared from them in comparatively few steps. When used for fabrication of photoelectrodes for dye-sensitized solar cells (DSSCs), the paste yielded highly transparent films and possessing greater-than-typical, thickness-normalized surface areas. ...

Organic anion-transporting polypeptides 1B1 and 1B3 (OATP1B1 and OATP1B3) are liver-specific transporters that mediate the uptake of a broad range of drugs into hepatocytes, including statins, antibiotics, and many anticancer drugs. Compounds that alter transport by one or both of these OATPs could potentially be used to target drugs to hepatocytes or improve the bioavailability of drugs that a...

Meniki (Chamecyparis formosensis) and Hinoki (C. obtusa) are precious conifers with excellent wood properties and distinctive fragrances that make these species popular in Taiwan for construction, interiors and furniture. In the present study, the compositions of essential oils prepared from Meniki and Hinoki were analyzed by gas chromatography-mass spectrometry (GC/MS). Thirty-six compounds we...

Compositions of true lavender (Lavandula angustifolia) and spike lavender (Lavandula latifolia) essential oils, cultivated and extracted in the Southeast of Spain, were determined by gas chromatography coupled with mass spectrometry detection, obtaining both relative (peak area) and absolute (using standard curves) concentrations. Linalool (37-54 %), linalyl acetate (21-36 %) and (E)-β-caryophy...

Eucalyptus cinerea, known as silver dollar tree, has few descriptions in traditional medicine. Chemical composition and antimicrobial properties of the essential oils of leaves, flowers and fruits, collected seasonally, were determined by GC/MS and disk diffusion/MIC, respectively. 1,8-Cineole was the main compound, particularly in fresh leaves-Spring (74.98%), dried leaves-Spring (85.32%), flo...

Pelargonium species are native to South Africa, and they have a long history in medicinal use. This study aimed extract essential oils from different parts of P. peltatum, determine the chemical composition oils, assess oils’ biological potential as analgesic anti-inflammatory agents. The were obtained by hydro-distilling profile was determined GC-FID GC-MS. activity oil using tail immersion ho...

Umbellularia californica (California bay laurel) and Laurus nobilis (Mediterranean bay laurel) leaves may be mistaken or used as a substitute on the market due to their morphological similarity. In this study, a comparison of anatomical and chemical features and biological activity of both plants is presented. L. nobilis essential oil biting deterrent and larvicidal activity were negligible. On...

Qualitative and quantitative chemical composition, activity against bacteria, yeasts and moulds and antioxidant activity of two variants (HV400 and HV3200) of hydrolates from dried lavender flowers (Lavandula angustifolia) were determined. The main chemical compounds were linalool (39.2% HV400, 29.0% HV3200), α-terpineol (7.1% HV400, 12.7% HV3200), borneol (4.8% HV400, 9.3% HV3200) and terpinen...

This research highlights the chemical composition, antioxidant, anti-inflammatory and anti-proliferative activities of essential oils from leaves of Ocimum basilicum, Ocimum americanum, Hyptis spicigera, Lippia multiflora, Ageratum conyzoides, Eucalyptus camaldulensis and Zingiber officinale. Essential oils were analyzed by gas chromatography-mass spectrometry and gas chromatography-flame ioniz...

the composition of the essential oils of nepeta crispa willd. and n. menthoides boiss. and buhse (lamiaceae) was investigated by means of gas chromatography (gc) and gc- mass spectrometery (ms). 1, 8-cineole was the most abundant component in oils: nepeta crispa (71%) and n. menthoides (41.1%). in the oil of n. crispa, b-pinene (5%) and d-terpineol (4.1%) were found to be the major constituents...
