(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 ...

A study on insect succession of monkey carcass in a forested area in Ulu Gombak, Selangor, Malaysia was conducted from 9 May to 18 June 2007. The third instar of the housefly, Musca domestica (Linnaeus) (Diptera: Muscidae) were only found on dry stage of a decomposed (Day-33) monkey carcass (Macaca fascicularis Raffles). This observation revealed that M. domestica maggots were found together wi...

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...

Climate change is likely to produce more frequent and longer droughts in the Mediterranean region, like that of 1994, which produced important changes in the Quercus ilex forests, with up to 76% of the trees showing complete canopy dieback. At the landscape level, a mosaic of responses to the drought was observed, linked to the distribution of lithological substrates. Damage to the dominant tre...

Quercus ilex (L.) leaves emit monoterpenes, particularly alpha-pinene, beta-pinene and sabinene. Apart from the monoterpene pools that are stored in specialized structures and have a clear defensive or attractive role, the function of monoterpenes in Q. ilex leaves is unknown. We tested whether monoterpenes have an antioxidant role, as has previously been found for isoprene in isoprene-emitting...

BACKGROUND AND AIMS In the last decades, the geographical location of the centre of origin of Quercus suber (cork oak), a strictly western Mediterranean oak species, has been the subject of controversy. METHODS RFLP variation over the whole chloroplast DNA molecule and PCR-RFLPs over seven specific cpDNA fragments were analysed phylogeographically to reconstruct the evolutionary history of co...
