España plató de cine: claroscuros de las rutas de cine y televisión
2020
El interés por visitar los lugares donde se rodaron las películas y series de televisión de éxito está presente en la motivación de los viajes recreativos que realizan millones de turistas por todo el mundo. Aunque la imagen internacional de España no se ha construido sobre esta modalidad de turismo, la mejora en las políticas de incentivos fiscales que se ofrecen a las producciones internacionales, junto con la decidida apuesta de los gestores de destinos por ampliar su oferta cultural con rutas de cine y el interés de la industria audiovisual por alargar la vida de las producciones ha revitalizado la vieja idea de convertir el territorio en un plató de cine. El estudio de una muestra repr…
Relatos de viajeros-escritores por la Ruta de la Seda en la era del turismo de masas: tras las huellas de los periplos del pasado
2019
El viaje en sus múltiples dimensiones es una de las experiencias más complejas acometidas por el ser humano. El deseo de conocer y descubrir, propio de esta experiencia, está indisolublemente unido a nuestra naturaleza. Asimismo, el viaje supone siempre un encuentro con lo desconocido, un juego incesante entre lo habitual y lo nuevo, entre la identidad y la alteridad. Se trata de una experiencia presente en todas las épocas y vivida por los viajeros de todos los tiempos. Actualmente el tema del viaje resulta complejo y polémico: nos desplazamos más que en cualquier otro momento de la historia, pero al mismo tiempo, hoy más que nunca, se habla de la crisis del viaje y de la lenta agonía de l…
Luxuria et mollitia: Rome’s textile raw material trade with the East
2014
A partir del Principado de Augusto, el Imperio romano comenzó a importar grandes cantidades de materias primas textiles y de tintes de lujo (luxuria) procedente de la India y de China. Este comercio provocó una reacción moralizante por parte de varios escritores, que vieron en la llegada de dichos productos un factor de afeminación de su sociedad (mollitia). From the Principate of Augustus onward, the Roman Empire began to import large quantities of textile raw materials as well as of luxury dyes (luxuria) from India and China. This trade caused a moralistic reaction by several writers, who saw in the arrival of these goods a factor of effeminacy of their society (mollitia).

Harvesting canthinones: identification of the optimal seasonal point of harvest of Zanthoxylum chiloperone leaves as a source of 5-methoxycanthin-6-o…
2015
This article is focused on the seasonal variation in the contents of 5-methoxycanthin-6-one from the leaves of Zanthoxylum chiloperone (Rutaceae). Based on the pharmacological interest presented by 5-methoxycanthin-6-one, its seasonal variation in Z. chiloperone leaves was analysed in order to determine the best time for harvesting, optimising the 5-methoxycanthin-6-one content. The seasonal dynamics of canthinone alkaloids can be the key to improve the isolation from natural sustainable sources, such as leaves. Complementarily, this study describes the phytochemistry of leaf from this Ruraceae species.
Citrus somatic hybrid leaf essential oil
2000
The essential oil from the leaves of a Citrus interspecific somatic hybrid obtained by symmetric protoplast fusion between ‘Milam’ lemon [purported sexual hybrid of C. Jambhiri Lush (×) C. sinensis] and ‘Femminello’ lemon (C. limon L. Burm f.) has been characterized by steam distillation GC–MS analysis and its composition compared with that of the corresponding oils obtained from the parent plants. The amount (%) of the different classes of substances present in the oils show, in the new hybrid, an overall lowering of the hydrocarbon fraction and an increase of the oxygenated components. The somatic hybrid shows a close similarity in the amounts of terpenes, sesquiterpenes and alcohols with…
Terpenoid Constituents ofZanthoxylum acanthopodiumDC. Leaves
2008
Abstract The chemical composition of the essential oil of Zanthoxylum acanthopodium DC. leaves was analyzed by GC and GC/MS. Fifty-eight compounds accounting for 75.6% of the oil were identified. The major compounds were linalool (14.3%), 9,12-octadecadien-ol (8.4%), 1,8-cineole (7.7%), 2-undecanone (7.3%), farnesol (3.6%), 9,12,15-octadecatrien-1-ol (3.2%) and β-caryophyllene (3.0%).
Free and conjugated polyamine content in Citrus sinensis Osbeck, cultivar Brasiliano N.L.92, a Navel orange, at different maturation stages
2004
Biogenic amines, synthesized during physiological metabolic processes of all living organisms, are present in food. At low concentrations, polyamines are essential for cell renewal and growth, but they can be detrimental when consumed in high amount through the diet as they could support abnormal cell growth pathologies. The daily human diet contains more putrescine than spermidine or spermine, mostly derived from fruits. In general, orange fruits contain high levels of put, a fact that could limit their utilization in the daily diet besides the benefits contributed by their strong antioxidant properties. There is therefore an increasing interest in finding plant foods with low polyamine co…
Cytotoxic alkaloids from the root of Zanthoxylum paracanthum (mildbr) Kokwaro
2021
Chemical investigation of the root of Zanthoxylum paracanthum afforded 1 new alkamide derivative, (2E,4E)-6-oxo-N-isobutyldeca-2,4-dienamide (1) together with 10 known congeners including one pheno...
Effect of polyamines on in vitro anther culture of Citrus clementina Hort. ex Tan
2006
The improvement of the induction rate in Citrus anther culture is important for taking practical advantage of the haploid potential in breeding. The influence of polyamines on anther culture of Citrus clementina, cv Nules, with particular attention to the free, soluble and insoluble-conjugated polyamine levels, has been investigated. Putrescine, spermidine and putrescine plus spermidine, were added to the standard induction medium. Before culture, spermidine was the most abundant among the free polyamines detected in anthers. The exogenous supply of either putrescine or spermidine, either independently or combined, effected greater uptake and accumulation of polyamines. The addition of 2 mM…
