Item MADRID (Marco Activo De Recursos de Innovación Docente). Madrid - Comunidad(2018) Baratas Díaz, Luis Alfredo; Becerra García, Nieves; Rodríguez López, Blanca María; Negro Alousque, Isabel; Cuervo Calvo, Laura; Rouanne, Laurence Louise Marcelle; González González, Juán Jesús; Maestre Varea, David; García Norro, Juan José; Ruiz Tendero, Germán; Pala Paul, Jesús; Ranchal Sánchez, Rocio; Rovira Madrid, Rogelio; Álvarez Serrano, Inmaculada; Cipres Palacín, María Ángeles; Reol Merino, Milagros; García Leal, María del Carmen Item Optimization of a Green Microwave-Assisted Extraction Method to Obtain Multifunctional Extracts of Mentha sp.(Foods, 2023) García-Sarrió, María J.; Sanz, María L.; Pala Paul, Jesús; Díaz Del Toro, Silvia; Soria, Ana C.A microwave-assisted extraction (MAE) procedure has been optimized to simultaneously provide multifunctional extracts of Mentha sp. leaves with improved antioxidant properties and, for the first time, with optimal antimicrobial activity. Among the solvents evaluated, water was selected as the extractant in order to develop a green procedure and also for its improved bioactive properties (higher TPC and Staphylococcus aureus inhibition halo). MAE operating conditions were optimized by means of a 3-level factorial experimental design (100 C, 14.7 min, 1 g of dry leaves/12 mL of water and 1 extraction cycle), and further applied to the extraction of bioactives from 6 different Mentha species. A comparative LC-Q MS and LC-QToF MS analysis of these MAE extracts was carried out for the first time in a single study, allowing the characterization of up to 40 phenolics and the quantitation of the most abundant. Antioxidant, antimicrobial (Staphylococcus aureus, Escherichia coli and Salmonella typhimurium) and antifungal (Candida albicans) activities of MAE extracts depended on the Mentha species considered. In conclusion, the new MAE method developed here is shown as a green and efficient approach to provide multifunctional Mentha sp. extracts with an added value as natural food preservatives.- Project number: 303
Item BaViBo: Banco Virtual de Botánica: retos online para estudiar y repasar prácticas(2023) Pala Paul, Jesús; Arias García, Concepción; De Soto Suárez, Lucía; Gavilán García, Rosario Gloria; Prada Moral, María Carmen; Puelles Gallo, María; Usano Alemany, Jaime; García Álvarez, Lorena; Martínez Atienza, Félix; Varela Sánchez, David; Abad Calderón, Rubén; Alonso Flores, Hugo; Belichenko, Mikhail; Bravo Castaño, Manuela; Lázaro Lobo, Adrián; Pérez Pérez, Yolanda Item Chemical composition of the essential oils of the Iberian peninsula endemic species eryngium dilatatum lam(Molecules, 2024) Pala Paul, Jesús; Pérez Alonso, María José; Soria, Ana; Brophy, JosephEryngium dilatatum Lam. is a thorny Iberian Peninsula endemic species belonging to the Apiaceae family that has not been previously analysed from a chemical point of view. Following our studies on this genus, we characterized the chemical composition of the essential oils from the different parts (inflorescences, stems + leaves, and roots) of this species; these parts were gathered in Cádiz (Spain). The specimens were collected in July during the flowering period and air-dried before the oil extraction by hydro-distillation. The essential oils were analysed by gas chromatography and gas chromatography coupled with mass spectrometry. The different parts of the plant yielded low amounts of pale yellow oil, with the roots being the fraction that provided the lowest amount of oil. The chemical characterization of the essential oils showed qualitative and quantitative differences between the fractions examined, but all of them showed the same principal compound, germacrene D (9.1–46.5%). Similarly, all the fractions shared most of their representative constituents, with their percentage compositions being different from one sample to the other: α-cadinol (3.8%), bicyclogermacrene (3.5%), octanal (3.1%), and spathulenol (2.5%) were found in the inflorescences; octanal (8.1%), α-cadinol (3.7%), δ-cadinene (3.6%), (E)-caryophyllene (2.6%), bicyclogermacrene (2.5%), and spathulenol (2.4%) were found in the stems and leaves; and spathulenol (4.6%), α-cadinol (4.4%), khusinol (3.2%), α-muurolol (3.1%), and δ-cadinene (2.6%) were found in the roots. As far as we know, this is the first report about the chemical composition of this endemic species of the Iberian Peninsula. It contributes to the knowledge of this species and to the genus to which it belongs. This species could be considered as a natural source of germacrene D, which is a sesquiterpene hydrocarbon with active properties.- Project number: 155
Item Etnobotánica "apprehendere et iocari" II(2019) Pérez Ruzafa, Isabel María; Cabezas Fuentes, Francisco José; Pala Paul, Jesús; Mártinez Atienza, Felix; Henández de Miguel, Jose María; Sabariego Ruíz, Silvia; Rubiales Jiménez, Juan Manuel; Rodríguez de Diego, Patricia; Díaz Luzza, Esteban Manuel; Arias García, Concepción; García Arias, Nuria - Project number: PIMCD191/23-24
Item REDINDMA: Recursos digitales para una nueva docencia aplicada en el área de marketing de la UCM(2024) Puelles Gallo, María; Pala Paul, Jesús; Abril Barrie, María Del Carmen; Arias García, Concepción; Narros González, María José; Abad Calderón, Rubén; Fernandez Olivar, Juan Carlos; Lopez Amador, Antonia; Rodriguez García, Rosa María; Belichenko, Mikhail; Bravo Castaño, Manuela; Gabriel y Galán Puelles, Santiago; Perez Perez, Yolanda; Usano Alemany, Jaime; Sanchez Manso, Leandro; Marín Casas, Iker; Puelles Gallo, MaríaLa presente memoria se refiere al proyecto de innovación pedagógica REDINDIMA, cuyo objetivo es proveer a los docentes del área de marketing de las Universidades españolas de recursos prácticos actualizados (casos) adaptados al entorno nacional, de modo que puedan ser comprendidos y aplicados por parte del profesorado y alumnado de forma más eficaz, y mejoren la adaptación y posibilidades de inserción laboral. A partir del diseño, contenidos y recorrido lógico por un caso práctico real y actual, se ha generado una aplicación que sirve de plataforma para la carga de nuevos casos y su administración guiada por el profesorado según el avance de los conocimientos teóricos durante el curso. Se parte de una lectura comprensiva de información general sobre un tema de marketing, que es evaluada online, para dar paso a los siguientes módulos referentes a aspectos concretos del área, con información, preguntas y actividades evaluables. En este caso de prueba, se ha planteado un recorrido amplio que da acceso a la profundización sobre política de producto, precio, comunicación, distribución comercial, comportamiento del consumidor e investigación de mercados, abarcando la práctica totalidad de las asignaturas de la especialidad. La aplicación está diseñada para que el profesorado pueda “cargar” sus propios casos en los módulos correspondientes, adaptando y normalizando las actividades dentro y fuera del aula para los alumnos. Item Phenotypic and Phytochemical Diversity among Different Accessions of Gijavash (Froriepia subpinnata (Ledeb.) Baill.: An Endemic Medicinal Plant Grown in Iran(Journal of Agricultural Science and Technology, 2020) Jorkesh, A.; Hamidoghli, Y.; Olfati, J.; Samizadeh, H.; Bakhshi, D.; Pala Paul, JesúsFroriepia subpinnata is an endemic endangered medicinal plant growing indigenous to Caspian coast forest in the north of Iran. This research was done to obtain primary information on morphological and phytochemical variation for the next step of domesticating and breeding of this plant. Twenty-three morphological traits measured indicated high variation among 52 accessions. There was a significant positive correlation between leaf dimension, plant height, and attributes related to biomass data. The range of phytochemical attributes analyzed was for total phenols (355.6-941.3 mg GAE 100 g-1 FW), total flavonoids (204.33-540.74 mg CAT 100 g-1 FW), total carotenoids (1.52 to 3.15 μg 100g-1 FW) and antioxidant capacity (31.36-81.82 DPPH%.). The HPLC analysis results showed that chlorogenic acid was the dominant phenolic compound generally found in this plant. Total carotenoids had no significant correlation with other biochemical traits, while the rest exhibited a linear relationship with each other. UPGMA cluster based on combined data of morphological and biochemical traits showed 3 distinct groups with high inter and intra-regional variations. Also, these information were combined with molecular data to separate environment and genetic effects. The high level of variation of phytochemical and morphological traits among and within populations could be a useful tool for future breeding and selection programs.Item Approach to the mycological catalogue of the Dehesa of Somosierra and new records for the Community of Madrid (Spain)(Botanica Complutensis, 2019) Rodríguez de Francisco, Borja; Lázaro-Lobo, Adrián; Pala Paul, JesúsAn approach to the mycological catalogue of the Dehesa of Somosierra, in the northeast corner of the Community of Madrid, has been carried out. The expeditions were accomplished from April 2013 to October 2015. A total of 96 species were identified belonging to 45 families and 18 orders. To the best of our knowledge, it is the first time that the species as Hyalorbilia inflatula, Panellus serotinus and Vibrissea filisporia f. boudieri have been cited in the Community of Madrid.
