Yerba mate (YM) is massively produced and consumed as an infusion in South America and is gaining popularity all over the world. This product is obtained from the dried leaves of Ilex paraguariensis Saint Hilaire, mixed with fragments of its dried branches. For its commercialization YM must have a minimum percentage of leaves according to a standard classification. Until now, composition quanti...

The effects of nitrogen (N) deposition, tropospheric ozone (O3) and their interaction were investigated in two Mediterranean tree species, Fraxinus ornus L. (deciduous) and Quercus ilex L. (evergreen), having different leaf habits and resource use strategies. An experiment was conducted under controlled condition to analyse how nitrogen deposition affects the ecophysiological and biochemical tr...

We tested whether growth and maintenance costs of plant organs vary with environmental stress. Quercus ilex L. seedlings from acorns collected from natural populations in the northern Iberian Peninsula and in a lower elevation and putatively less stressful habitat in the southern Iberian Peninsula were grown in pots under the same conditions. Growth and maintenance respiration were measured by ...

(eds.), Sulfur Metabolism in Plants, Proceedings of the International Plant Sulfur Workshop 1, DOI 10.1007/978-94-007-4450-9_29, © Springer Science+Business Media Dordrecht 2012 Abstract The effect of long-term exposure to elevated p CO 2 concentrations on sulfate and nitrate assimilation was studied under fi eld conditions using leaves from Quercus ilex and Quercus pubescens...

(12E,14E,17E)-11-Hydroxy-12,14,17-dodecatrienoic acid was isolated from the stems of Ilex integra and its structure was determined on the basis of the spectroscopic data of its methyl ester.

I read the article entitled “Effect of Lumbar Stabilization and Dynamic Lumbar Strengthening Exercises in Patients With Chronic Low Back Pain” by Moon et al. [1] with interest. However, I would like to offer some comments regarding its results and methodology reported. Moon et al. [1] compared ‘Lumbar Stabilization’ exercises with ‘Dynamic Lumbar Strengthening’ exercises. However the exercises ...

Ilex paraguariensis St.Hil. é uma espécie de importância econômica tendo em vista sua utilização na região meridional da América do Sul no preparo do chimarrão, uma bebida estimulante, preparada pela infusão de suas folhas e talos moídos. Este trabalho apresenta a análise de metilxantinas em folhas de I. paraguariensis e outras espécies de Ilex freqüentemente relatadas como adulterantes. A dete...

We studied the seasonal patterns of water use in three woody species co-occurring in a holm oak forest in northeastern Spain. The three species studied, Quercus ilex L., Phillyrea latifolia L. and Arbutus unedo L., constitute more than 99% of the total basal area of the forest. The study period included the dry seasons of 1999 and 2000. Water use was estimated with Granier-type sap flux sensors...
