Spanish Medicinal Plants. Achillea millefolium L. (Milfoi)

En la presente monografía sobre Achillea millefolium L. se incluye la descripción botánica, ecología, corología, cultivo, recoleción y conservación de la especie. Se analizan las características morfológicas y anatómico-microscópicas de los órganos oficinales, para después aplicar estos conocimientos a la planta troceada (trociscos). Se estudian las aplicaciones terapéuticas, una vez vista la composición química y su acción farmacológica. Se hace referencia a su posible toxicidad, contraindicaciones y control de calidad. Finalmente, se tratan algunos aspectos de la formulación.The present monographic of Achillea millefolium L. contains the botanical descripcion of the plant, ecology, corology, growing, gathering and the drug conservation. The morphological and anatomical microscopic characteristics of the oficinal organs are analysed, after that, these knowledges are applied to the plant fragments.The therapeutical applications are studied once its chemical composition and its pharmacological action are analised. We have made reference to its possible toxicology, to its contraindications and to its quality control.Finally, some formulation aspects are dealed whith

Arsenic distribution in a pasture area impacted by past mining activities

[EN]Former mine exploitations entail a serious threat to surrounding ecosystems as after closure of mining activities their unmanaged wastes can be a continuous source of toxic trace elements. Quite often these mine sites are found within agricultural farming areas, involving serious hazards as regards product (feed/food) quality. In this work a grazing land impacted by the abandoned mine exploitation of an arsenical deposit was studied so as to evaluate the fate of arsenic (As) and other trace elements and the potential risks involved. With this aim, profile soil samples (0–50 cm) and pasture plant species (Agrostis truncatula, Holcus annus and Leontodon longirostris) were collected at different distances (0–100 m) from the mine waste dump and analyzed for their trace element content and distribution. Likewise, plant trace element accumulation from impacted grazing soils and plant trace element translocation were assessed. The exposure of livestock grazing animals to As was also evaluated, establishing its acceptability regarding food safety and animal health. International soil guideline values for As in grazing land soils (50 mg kg−1) resulted greatly exceeded (up to about 20-fold) in the studied mining-affected soils. Moreover, As showed a high mobilization potential under circumstances such as phosphate application or establishment of reducing conditions. Arsenic exhibited relatively high translocation factor (TF) values (up to 0.32–0.89) in pasture plant species, reaching unsafe concentrations in their above-ground tissues (up to 32.9, 16.9 and 9.0 mg kg−1 in Agrostis truncatula, Leontodon longirostris and Holcus annus, respectively). Such concentrations represent an elevated risk of As transfer to the high trophic-chain levels as established by international legislation. The limited fraction of arsenite found in plant roots should play an important role in the relatively high As root-to-shoot translocation shown by these plant species. Both soil ingestion and pasture intake resulted important entrance pathways of As into livestock animals, showing quite close contribution levels. The cow acceptable daily intake (ADI) of As regarding food safety was surpassed in some locations of the study area when the species Agrostis truncatula was considered as the only pasture feed. Restrictions in the grazing use of lands with considerable As contents where this plant was the predominant pasture species should be established in order to preserve food quality. Therefore, the exposure of livestock animals to As via both soil ingestion and pasture consumption should be taken into account to establish the suitability of mining-impacted areas for gazing

New cytotoxic neolignans from the cobalt crust fungus

Terana coerulea (Phanerochaetaceae family) is known as the cobalt crust fungus and it is used for its antibiotic properties at the Irati’s Forest (Navarra, Spain). Previous mycochemical investigations reported the isolation of corticins A-C,[1] p-terphenyl neolignans related to the antitumoural telephoric acid.[2] In this job, from powdered dry fungi, six extracts of increasing polarity were obtained and tested for cytotoxicity against four human tumour cell lines and one non-tumour primary cell culture with the sulforhodamine B assay. From the most cytotoxic one, the EtOAc extract, we isolated and identified three p-terphenyl neolignans. One of them was previously described as corticin A by Briggs et al.,[1] whose earlier structure has been revised in this work using one- and two-dimensional NMR, HRMS, positive and negative MS/MS and its peracetyl derivative in comparison with 4’’-deoxy and 4,5-dimethoxy candidusines A.[3] The other two neolignans are new natural products, named corticins D and E. These neolignans were less cytotoxic than the EtOAc extract itself, maybe due to an aerial oxidation and degradation produced when these neolignans, with catechol moieties, are definitively purified.info:eu-repo/semantics/publishedVersio
