The structures of thirty three compounds were tentatively identiﬁed by liquid chromatography coupled to electrospray ionisation mass spectrometry (HPLC–DAD/ESI–MS). The majority of those compounds were gallic acid derivatives, in the form of either galloyl esters of glucose (gallotannins), combinations of galloyl and hexahydroxydiphenoyl esters of glucose (ellagitannins), dehydrated tergallic-C-glucosides or ellagic acid derivatives. Others were found to correspond to low molecular weight phenolic compounds, like acids and aldehydes. Mongolicain, a ﬂavanoellagitannin in which hydrolysable tannin and ﬂavan-3-ol moieties are connected through a carbon–carbon linkage, was also detected in cork from Q. suber L. The results illustrate the rich array of phenolic compounds present in cork.</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Fernandes, Ana</style></author><author><style face="normal" font="default" size="100%">Fernandes, Iva</style></author><author><style face="normal" font="default" size="100%">Cruz, Luís Luís</style></author><author><style face="normal" font="default" size="100%">Mateus, Nuno</style></author><author><style face="normal" font="default" size="100%">Cabral, Miguel</style></author><author><style face="normal" font="default" size="100%">de Freitas, Victor</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Antioxidant and Biological Properties of Bioactive Phenolic Compounds from Quercus suber L.</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Agricultural and Food Chemistry</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">antioxidants</style></keyword><keyword><style  face="normal" font="default" size="100%">Antioxidants: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Antioxidants: isolation &amp; purification</style></keyword><keyword><style  face="normal" font="default" size="100%">Antioxidants: pharmacology</style></keyword><keyword><style  face="normal" font="default" size="100%">Antitumor activity</style></keyword><keyword><style  face="normal" font="default" size="100%">Cell Line</style></keyword><keyword><style  face="normal" font="default" size="100%">Cell Proliferation</style></keyword><keyword><style  face="normal" font="default" size="100%">Cell Proliferation: drug effects</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork</style></keyword><keyword><style  face="normal" font="default" size="100%">Humans</style></keyword><keyword><style  face="normal" font="default" size="100%">Hydrolyzable Tannins</style></keyword><keyword><style  face="normal" font="default" size="100%">Hydrolyzable Tannins: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Hydrolyzable Tannins: isolation &amp; purification</style></keyword><keyword><style  face="normal" font="default" size="100%">Hydrolyzable Tannins: pharmacology</style></keyword><keyword><style  face="normal" font="default" size="100%">phenolic compounds</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Extracts</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Extracts: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Extracts: isolation &amp; purification</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant Extracts: pharmacology</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber L.</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus: chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Tumor</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2009</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2009///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/19888728http://dx.doi.org/10.1021/jf902093m</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">57</style></volume><pages><style face="normal" font="default" size="100%">11154 - 11160</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Phenolic compounds, namely, hydrolyzable tannins and low molecular weight phenolic compounds, were isolated and purified from Portuguese cork from Quercus suber L. Some of these compounds were studied to evaluate their antioxidant activity, including free-radical scavenging capacity (DPPH method) and reducing capacity (FRAP method). All compounds tested showed significant antioxidant activity, namely, antiradical and reducing properties. The antiradical capacity seemed to increase with the presence of galloyl groups. Regarding the reducing capacity, this structure-activity relationship was not so clear. These compounds were also studied to evaluate the growth inhibitory effect on the estrogen responsive human breast cancer cell line (ERþ) MCF-7 and two other colon cancer cell lines (Caco-2 and HT-29). Generally, all the compounds tested exhibited, after a continuous exposure during a 48 h period, a dose-dependent growth inhibitory effect. Relative inhibitory activity was primarily related to the number of phenolic hydroxyl groups (galloyl and HHDP moieties) found in the active structures, with more groups generally conferring increased effects, except for HHDP-di-galloyl-glucose. Mongolicain B showed a greater potential to inhibit the growth of the three cell lines tested, identical to the effect observed with castalagin. Since these compounds are structurally related with each other, this activity might be based within the C-glycosidic ellagitannin moiety.</style></abstract><issue><style face="normal" font="default" size="100%">23</style></issue><notes><style face="normal" font="default" size="100%">From Duplicate 2 (Antioxidant and Biological Properties of Bioactive Phenolic Compounds from Quercus suber L. - Fernandes, Ana; Fernandes, Iva; Cruz, Luís; Mateus, Nuno; Cabral, Miguel; de Freitas, Victor)From Duplicate 2 (Antioxidant and Biological Properties of Bioactive Phenolic Compounds from Quercus suber L. - Fernandes, Ana; Fernandes, Iva; Cruz, Luís; Mateus, Nuno; Cabral, Miguel; de Freitas, Victor)The following values have no corresponding Zotero field:&lt;br/&gt;publisher: American Chemical Society&lt;br/&gt;accession-num: 19888728</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">El Kbiach, M.

Nematodes were present in all soils. The organic matter was higher in forest soils. Water extracts from forest soils with high levels of phenols, leaf litter and Q. rotundifolia fresh leaves aﬀected the development and growth of common species of nematophagous and entomopathogenic fungi. These results show that phenolics from leaf letter could play an important role in the ecology and biology of these invertebrate pathogens in soil.</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue></record></records></xml>
