Disease relevance of Fraxinus

• Occupational asthma and rhinitis caused by ash (Fraxinus excelsior) wood dust [1].

High impact information on Fraxinus

• Historical and contemporary mating patterns in remnant populations of the forest tree Fraxinus excelsior L [2].
• The allergen profile of ash (Fraxinus excelsior) pollen: cross-reactivity with allergens from various plant species [3].
• Isolation and purification of coumarin compounds from Cortex fraxinus by high-speed counter-current chromatography [4].
• 14.3 mg of fraxin, 26.5 mg of aesculin, 5.8 mg of fraxetin and 32.4 mg of aesculetin with the purity of 97.6, 99.5, 97.2 and 98.7%, respectively were obtained from 150 mg of crude extracts of C. fraxinus in a single run [4].
• High-speed counter-current chromatography (HSCCC) was successfully used for the isolation and purification of coumarin compounds from Cortex fraxinus, the Chinese herbal drug. n-Butanol-methanol-0.5% acetic acid (5:1.5:5, v/v) was used as the two-phase solvent system [4].

Biological context of Fraxinus

• Nuclear microsatellites reveal contrasting patterns of genetic structure between western and southeastern European populations of the common ash (Fraxinus excelsior L.) [5].
• We report on diurnal and seasonal variations in sap flow rate and stem water potential of Fraxinus excelsior L. saplings growing at the edge of a Fraxino-Aceretum forest in western Germany. Because of shallow soil, the trees were subjected to drought in summer [6].
• While there were no significant changes in heart rate (HR) after Fraxinus excelsior treatment in both SHR and WKY rats, glomerular filtration rate (GFR) showed a significant increase in SH rats (p<0.001) after Fraxinus excelsior treatment [7].

Associations of Fraxinus with chemical compounds

• The phenols in beech (Fagus sylvatica), birch (Betula pendula) and ash (Fraxinus excelsior) wood dusts were compared using a mass spectrometer fitted with an electrospray ionisation interface with liquid chromatographic separation [8].
• Bioassay-guided fractionation of an H2O extract of the barks of Fraxinus rhynchophylla has furnished two inducible nitric oxide synthase (iNOS) inhibitory compounds, ferulaldehyde (1) and scopoletin (3) together with a coumarin, fraxidin (2) [9].
• Effect of NaCl and mannitol iso-osmotic stresses on proline and free polyamine levels in embryogenic Fraxinus angustifolia callus [10].
• In greenhouse studies with intact soil cores, acenaphthene, anthracene, fluoranthene, naphthalene, and phenanthrene decreased significantly (p < 0.05) in green ash (Fraxinus pennsylvanica Marshall) and hybrid poplar (Populus deltoides x P. nigra DN 34) phytoremediation treatments when compared to the unplanted soil control [11].
• Regulation by uniconazole-P and gibberellins of morphological and anatomical responses of Fraxinus mandshurica seedlings to gravity [12].

Gene context of Fraxinus

• Physiological and foliar symptom response in the crowns of Prunus serotina, Fraxinus americana and Acer rubrum canopy trees to ambient ozone under forest conditions [13].

Analytical, diagnostic and therapeutic context of Fraxinus

• Comparison of cryopreservation techniques for long-term storage of ash (Fraxinus excelsior L.) [14].
• The mannitol content of leaves of Fraxinus ornus L., F. angustifolia Vahl., Olea europaea L. and Phillyrea media L. was determined by gas chromatography [15].
• The purpose of this study was to determine the underlying mechanism of the hypoglycaemic activity of the aqueous extract perfusion of Fraxinus excelsior L [16].
