Rockrose and quebracho condensed tannins have a minor impact on the fatty acid ...
Jerónimo, Eliana; Guerreiro, Olinda; Soldado, David; Fialho, Letícia; Cachucho, Liliana; Garrido, Ana; Conceição, Cristina; Bessa, Rui; Silva, JoséThis study was carried out to test the hypothesis that the inclusion of condensed tannins (CT) from rockrose (Cistus ladanifer L.) and quebracho (Schinopsis lorentzii) in dairy goat diets supplemented with vegetable oil rich in polyunsaturated fatty acids (PUFA) can increase the potentially healthy fatty acids (FA) in milk and cheese fat, without compromising animal performance and milk and cheese composition. ...
Influence of Sex on Meat and Fat Quality from Heavy Alentejano Pigs Finished Ou...
Martins, José Manuel; Charneca, Rui; Garrido, Nicolás; Albuquerque, André; Jerónimo, Eliana; Guerreiro, Olinda; Lage, Patrícia; Marmelo, CarlaThis work aimed to examine the effects of sex on meat and fat quality traits from thirty Portuguese Alentejano (AL) pigs reared in outdoor conditions. These pigs were divided into three groups and fed ad libitum. From ~40 to 130 kg LW, castrated (C group) and intact animals (I and IExp) consumed commercial diets. Until slaughter (~160 kg), C and I pigs remained on commercial diets, and IExp changed to a more su...
Effects of increasing doses of condensed tannins extract from Cistus ladanifer ...
Guerreiro, Olinda; Alves, Susana P.; Costa, Mónica; Duarte, Maria F.; Jerónimo, Eliana; Bessa, R.J.B.Cistus ladanifer (rockrose) is a perennial shrub quite abundant in the Mediterranean region, and it is a rich source in secondary compounds such as condensed tannins (CTs). Condensed tannins from C. ladanifer were able to change the ruminal biohydrogenation (BH), increasing the t11–18:1 and c9,t11–18:2 production. However, the adequate conditions of the C. ladanifer CTs used to optimize the production of t11–18...

Delgado, Inês; Zúquete, Sara; Soldado, David; Guerreiro, Olinda; Jerónimo, Eliana; Padre, LudovinaEvaluation of Cistus ladanifer L. effect on gastrointestinal parasites in lambs Inês Delgadoa, Sara Tudela Zúquete, David Soldado, Olinda Guerreiro, Eliana Jerónimo, Ludovina Neto Padre Cistus ladanifer L. (Cistaceae) is a bountiful available shrub at the western Mediterranean region, including the south of France, Spain, Portugal and the north of Morocco. It is commonly observed in uncultivated fields. This pe...
Phenolic composition and antioxidant activity of different morphological parts ...
Ramos, Patricia A. B.; Santos, Sonia A. O.; Guerra, Angela R.; Guerreiro, Olinda; Freire, Carmen S. R.; Rocha, Silvia M.; Duarte, Maria F.The phenolic composition of Cynara cardunculus L. var. altilis (DC) from south of Portugal was determined by analyzing the methanol/water/acetic acid (49.5:49.5:1) extracts of the different morphological parts of the plant, through high temperature-ultra high pressure liquid chromatography tandem mass spectrometry. From the twenty-eight phenolic compounds identified, eriodictyol hexoside was described for the f...
Lipophilic Extracts of Cynara cardunculus L. var. altilis (DC): A Source of Val...
Ramos, Patricia A. B.; Guerra, Angela R.; Guerreiro, Olinda; Freire, Carmen S. R.; Silva, Artur M. S.; Duarte, Maria F.; Silvestre, Armando J. D.Lipophilic extracts of Cynara cardunculus L. var. altilis (DC) from the south of Portugal (Baixo Alentejo) were studied by gas chromatographymass spectrometry. One sesquiterpene lactone, four pentacyclic triterpenes, and four sterols were reported for the first time as cultivated cardoon components, namely, deacylcynaropicrin, beta- and alpha-amyrin, lupenyl and psi-taraxasteryl acetates, stigmasterol, 24-methy...
Valorization of olive mill residues: Antioxidant and breast cancer antiprolifer...
Ramos, Patricia; Santos, Sonia A. O.; Guerra, Angela R.; Guerreiro, Olinda; Felicio, Laura; Jeronimo, Eliana; Silvestre, Armando J. D.Phenolic composition, antioxidant and breast cancer antiproliferative activities of water and methanol/water derived extracts from olive pomace (OP) and dry olive mill residue (DOR), from Portuguese industries, were studied. DOR water (DORW) extracts showed the highest extraction yield; as well as the highest total phenolic content (TPC) and hydroxytyrosol (HT) (similar to 25 mg/g extract). HPLC-ESI-MS analysis...

Ramos, Patrícia; Santos, Sónia; Guerra, Ângela; Guerreiro, Olinda; Felício, Laura; Jerónimo, Eliana; Silvestre, Armando; Neto, Carlos PascoalPhenolic composition, antioxidant and breast cancer antiproliferative activities of water and methanol/water derived extracts from olive pomace (OP) and dry olive mill residue (DOR), from Portuguese industries, were studied. DOR water (DORW) extracts showed the highest extraction yield; as well as the highest total phenolic content (TPC) and hydroxytyrosol (HT) (∼25 mg/g extract). HPLC–ESI-MS analysis identifie...
Biological characterization of Cynara cardunculus L. Methanolic extracts: antio...
Velez, Zélia; Campinho, Marco António; Guerra, Ângela R.; García, Laura; Ramos, Patricia; Guerreiro, Olinda; Felício, Laura; Schmitt, Fernando<i>Cynara cardunculus</i> (Cc) is a multipurpose species; beyond its use in southwestern European cuisine, it is also used for the production of solid biofuel, seed oil, biodiesel, paper pulp and cheese, as well as animal feed. In addition, Cc has a long tradition of use in folk medicine as a diuretic and liver protector. The value of this species as a source of bioactive compounds is known; however, pharmacolo...
