Spatial and temporal variation of community composition and species cover following dune restoration in the Devesa de Albufera (Valencia, Spain).
2015
Plant populations were reintroduced to the coastal dune bar of the Devesa de Albufera from 1988 to 2004; different coastline sections received different species composition and cover. With the aim to detect spatial and temporal variation of floristic diversity, we compared current species composition and cover across the length of the Devesa and across the dune bar with those imposed at the time of restoration. Non-metric multidimensional scaling (NMDS) detected significant differences both across the dune faces and across the coast sections. Differences across the dune faces reflect the sea-inland ecological gradient and resulted from a spatial rearrangement of plant populations: Calystegi…
Phytochemical analysis ofAchillea ligusticaAll. from Lipari Island (Aeolian Islands)
2016
A complete chemical investigation of Achillea ligustica All. growing at Lipari (Aeolian Island, Sicily) has been carried out. Seventeen metabolites have been isolated and characterised from dichloromethane and methanol extracts of flowers and aerial parts, and GC/MS analyses of petroleum ether extracts was carried out, revealing a composition in sesquiterpenoids similar to those reported for populations from Greece, Sicily and Algeria, showing the presence of (3RS,6RS)-2,6-dimethyl-1,7-octadiene-3,6-diol (1), 2,6-dimethyl-octa-3(E),7-diene-2,6-diol (2), iso-seco-tanapartholide (3) from DCM fraction. In addition from the methanolic extract of the aerial parts, peculiar flavonoid glucuronides…
Composition and antimicrobial activity of the essential oil of Achillea falcata L. (Asteraceae).
2005
The composition of the essential oil from aerial parts of Achillea falcata L. (Asteraceae) growing wild in Lebanon was analysed by GC and GC–MS; 58 compounds, representing 94.4% of the oil, were identified. Isomers of the cyclobutane ethanol, 1-methyl-2-(1-methylethenyl), grandisol (21.4%) and fragranol (16.8%) were the main components of the oil. Also abundant were artemisia ketone (5.2%), terpinen-4-ol (4.5%) and 1,8-cineole (4.0%). The essential oil shows inhibitory activity mainly against Gram-positive bacteria.
Synthesis of 3-Oxa-guaianolides from Santonin
2000
Abstract This article reports on the transformation of santonin into two C10-epimeric 3-oxa-guaianolides which are 8-deoxyderivatives of several natural 3-oxaguaianolides isolated from Achillea species. The synthesis involved the photochemical rearrangement of the eudesmane skeleton into a guaiane skeleton and the transformation of the cyclopentane ring into a furan moiety with the concomitant loss of C3. Comparison of the NMR data of the synthetic products with those of the natural products confirms the β orientation of the hydroxyl group at C10 in the products isolated from Achillea.
Medicinal plants and their uses recorded in the Archives of Latvian Folklore from the 19th century.
2020
Abstract Ethnopharmacological relevance The records of folk medicine present historical evidence of medicinal plant usage in the territory of Latvia and describe native and imported plants and plant products that were used as medicine. Aim of the study To collect and analyse the ethnobotanical knowledge found in records of Latvian folk medicine available in the Archives of Latvian Folklore. Materials and methods Following the International Classification of Primary Care, plant uses were grouped into one of the 17 categories based on the body systems and psychological and social problems. Each plant was identified by its scientific name according to The Plant List website. Additionally, the …
Modulation of Cox-1, 5-, 12- and 15-Lox by Popular Herbal Remedies Used in Southern Italy Against Psoriasis and Other Skin Diseases
2014
Acanthus mollis (Acanthaceae), Achillea ligustica, Artemisia arborescens and Inula viscosa (Asteraceae) are used in Southern Italy against psoriasis and other skin diseases that occur with an imbalanced production of eicosanoids. We here assessed their in vitro effects upon 5-, 12-, 15-LOX and COX-1 enzymes as well as NFκB activation in intact cells as their possible therapeutic targets. All methanol crude extracts inhibited both 5-LOX and COX-1 activities under 200 µg/mL, without significant effects on the 12-LOX pathway or any relevant in vitro free radical scavenging activity. NFκB activation was prevented by all extracts but A. mollis. Interestingly, A. ligustica, A. arborescens and A. …
Status of Some Escaped Ornament Perennials in the Flora of Latvia
2019
AbstractThis paper introduces eight ornamental perennial garden escapees that were recorded by the authors of this article on Lucavsala Island, Riga (Latvia) in 2016. Our data on Achillea ptarmica cv. ‘Boule de Neige’, Artemisia ludoviciana, Asclepias syriaca, Campanula lactiflora, Heliopsis helianthoides, Lathyrus latifolius, Phlox paniculata and Rudbeckia hirta contribute to the knowledge about the occurrence of these taxa in wild. All these species are also growing in the collection of ornamental perennials in the Botanical Garden of the University of Latvia. A review of these species in Latvian herbarium collections has been conducted. Five species, Heliopsis helianthoides, Artemisia lu…
Chemical Composition and Free Radical Scavenging Activity of the Essential Oil of Achillea ligustica Growing Wild in Lipari (Aeolian Islands, Sicily)
2013
In the present study the chemical composition of the essential oils from aerial parts and flowers of Achillea ligustica All., collected in Lipari (Aeolian Islands) was evaluated by GC and GC-MS. ( Z)-Chrysanthenyl acetate was the most abundant component of both oils (29.6% in A1 and 27.8% in F1), followed by viridiflorol (16.8% in A1 and 21.6% in F1), bornyl acetate (8.7% in A1 and 11.6% in F1) and 1,8-cineole (7.4% in A1 and 9.3% in F1). A comparison was made of the composition of the different populations studied so far. Futhermore, the free radical scavenging activity of the oil was determined by DPPH and ABTS methods.
Endophytic Bacterial Community Structure and Function of Herbaceous Plants From Petroleum Hydrocarbon Contaminated and Non-contaminated Sites
2018
Bacterial endophytes (BEs) are non-pathogenic residents of healthy plant tissues that can confer benefits to plants. Many Bacterial endophytes have been shown to contribute to plant growth and health, alleviation of plant stress and to in-planta contaminant-degradation. This study examined the endophytic bacterial communities of plants growing abundantly in a heavily hydrocarbon contaminated site, and compared them to those found in the same species at a non-contaminated. We used culture- dependent and independent methods to characterize the community structure, hydrocarbon degrading capabilities, and plant growth promoting traits of cultivable endophytes isolated from Achillea millefolium,…
The chemical composition of the aerial parts essential oil of Achillea cretica L. (Asteraceae) growing wild in Crete (Greece)
2022
Achillea cretica (L.) (Asteraceae) is a suffruticosa camefite plant, mainly distributed in Crete, Aegean Islands, and eastern Mediterranean area. In the present study, the chemical composition of the essential oil from aerial parts of a not previously investigated accession of Achillea cretica, collected in Crete, was analysed by GC-MS. The results showed the presence of large quantity of α-bisabolol (53.88%) followed by the related compound α-bisabolol-oxide (2.76%), and spathulenol (5.94%). Based on the composition of the essential oils of all the other Achillea taxa, several consideration have been carried out.
