Early Miocene marsupialiforms, gymnures, and hedgehogs from Ribesalbes-Alcora Basin (Spain)
2020
AbstractMaterials from the localities of Araia d'Alcora in the Ribesalbes-Alcora Basin (Spain, early Miocene, Biozone C, MN4) have yielded an assemblage of erinaceids and metatherians, relatively rich for an Iberian site. The most common erinaceid is the gymnureGalerix symeonidisiDoukas, 1986, present in almost all of the studied sites. Other erinaceids in the faunal list are possibly an indeterminate species of the generaLantanotheriumFilhol, 1888 andAtelerixPomel, 1848, in what constitutes one of their oldest occurrences in Europe. Metatherians are represented by the herpetotheriidAmphiperatherium frequens erkertshofense(Koenigswald, 1970). The material described here was partially publis…
HorTILLUS—A Rich and Renewable Source of Induced Mutations for Forward/Reverse Genetics and Pre-breeding Programs in Barley (Hordeum vulgare L.)
2018
TILLING (Targeting Induced Local Lesions IN Genomes) is a strategy used for functional analysis of genes that combines the classical mutagenesis and a rapid, high-throughput identification of mutations within a gene of interest. TILLING has been initially developed as a discovery platform for functional genomics, but soon it has become a valuable tool in development of desired alleles for crop breeding, alternative to transgenic approach. Here we present the HorTILLUS ( Hordeum-TILLING-University of Silesia) population created for spring barley cultivar "Sebastian" after double-treatment of seeds with two chemical mutagens: sodium azide (NaN3) and N-methyl-N-nitrosourea (MNU). The populatio…
Isolation and identification of new anthraquinones from Rhamnus alaternus L and evaluation of their free radical scavenging activity
2018
From the butanolic and the ethyl acetate extracts of Rhamnus alaternus L root bark and leaves, three new anthraquinone glycosides, alaternosides A-C (1,4,6,8 tetrahydroxy-3 methyl anthraquinone 1-O-ß-D-glucopyranosyl-4,6-di-O-α-L-rhamnopyranoside (1); 1,2,6,8 tetrahydroxy-3 methyl anthraquinone 8-O-ß-D-glucopyranoside (2) and 1, 6 dihydroxy-3 methyl 6 [2′-Me (heptoxy)] anthraquinone (3)) were isolated and elucidated together with the two known anthraquinone glycosides, Physcion-8-O-rutinoside (4) and emodin-6-O-α-L-rhamnoside (5) as well as with the known kaempferol-7-methylether (6), β-sitosterol (7) and β-sitosterol-3-O-glycoside (8). Their chemical structures were elucidated using spectr…
Situación actual de Dictamnus hispanicus Webb (Rutaceae) en la provincia de Alicante: distribución y aspectos etnobotánicos
2017
El tarraguillo (Dictamnus hispanicus) es un endemismo de la mitad oriental de la Península Ibérica que posee notable relieve por sus usos tradicionales en la provincia de Alicante (Comunidad Valenciana, España), donde forma parte de los ‘herberos’ o licores de hierbas silvestres. Sin embargo, existe aún poca información sobre el resto de usos de la planta en esa provincia. Para incrementar dicho conocimiento, se han realizado encuestas semiestructuradas (n=90) y se ha completado la información sobre su distribución mediante el empleo de Sistemas de Información Geográfica, localizándose referencias para 27 cuadrículas UTM de 1×1 km. Se han recogido 5 fitónimos en valenciano (74,44 % de los i…

Revision of the Eduardo Reyes Prósper’s herbarium and typification of three species of charophytes (<em>Charophyceae : Characeae</em>) pr…
2019
A study of the charophytes collected by Eduardo Reyes Prósper in the period 1904–1906 and kept in the herbarium of the Royal Botanical Garden of Madrid (MA-ALGAE) is carried out. Reyes Prósper’s herbarium consists of 112 sheets, which had not been revised until now, among which are the type materials of Lamprothamnus aragonensis Reyes y Prosper, Lamprothamnus toletanus Reyes y Prosper and Tolypella giennensis Reyes y Prosper, of which their lectotypes are here designated.
Apulogalerix pusillus nov. gen., nov. sp., the small-sized Galericinae (Erinaceidae, Mammalia) from the ‘‘Terre Rosse’’ fissure filling of the Gargan…
2013
Abstract A small moonrat belonging to the Galericini tribe occurs in all the assemblages from the Terre Rosse fissure fillings of the Gargano. It was first mentioned in the pioneering report of Freudenthal and by Butler in his study of the “gigantic” Deinogalerix, and has been quoted with different names several times in faunal lists of the Terre Rosse endemic faunas. Up to date, however, the description of this gymnure has never been achieved. We present here the taxonomical and morphological description of a sample from Fissure Filling F32 that is considered to document the youngest phase of population of the Gargano Paleoarchipelago. The comparisons with genera Galerix, Parasorex and Sch…
Sobre los tipos nomenclaturales de dos táxones de Rhamnus (Rhamnaceae) de la flora valenciana
2015
Se designan los tipos nomenclaturales de dos taxones del género Rhamnus descritos de las comarcas valencianas. Por un lado, se lectotipifica el nombre Rh. lycioides var. pubescens Rouy −sinónimo de Rh. lycioides subsp. borgiae Rivas Mart. & J.M. Pizarro−, a partir del material original recolectado en las montañas de Játiva (Valencia). Por otro, se considera que el neótipo recientemente designado para el nombre Rh. valentina Willd. −sinónimo de Rh. pumila L.−, debería aceptarse realmente como un lectótipo. Nomenclatural types are designated for two taxa of the genus Rhamnus described from the Valencia Region (E of Spain). On the one hand, the name Rh. lycioides var. pubescens Rouy −a synonym…
Composition of the Essential Oil ofDictamnus hispanicusfrom Spain
2006
The composition of the essential oil of Dictamnus hispanicus Webb ex. Willk. collected in eastern Spain was analyzed by GC and GC/MS. The main constituents identified were methyl chavicol (79%) and limonene (7%). The high oil yield (72.0% fresh plant material) and the proportion of the main compounds support the consideration of D. hispanicus as a separate species of the S. and CS. Europe as D. albus aggregate or as a new chemotype of the polymorphic D. albus.
A hypotensive procyanidin-glycoside from Rhamnus lycioides ssp. lycioides.
1990
A lyophilized hot water extract of the aerial parts of Rhamnus lycioides L. (Rhamnaceae) produced a lowering of systemic arterial blood pressure in normotensive anaesthetized Wistar rats. An activity-guided fractionation of the methanolic extract led to the isolation of a tetrameric procyanidin-glycoside which produced a clear dose-dependent hypotensive response (1.5-6 mg/kg i.v.). This principle was characterized using acid hydrolysis, thiolytic degradation and spectroscopic methods. It consisted of four flavanol units with a 2,3-cis configuration and with a O-beta-d-glucosylpyranoside function on the epicatechin terminal unit. The interflavan linkage was (4-8).
