Composition and allelopathic effect of essential oils of two thistles: Cirsium creticum (Lam.) D.�Urv. ssp. triumfetti (Lacaita) Werner and Carduus n…
2007
Abstract Cirsium and Carduus are two of the main genera of true thistles. Different species in these genera share a quantity of secondary metabolites and have interesting ecological properties. The essential oils of two species, Cirsium creticum and Carduus nutans, were analysed, showing the presence as main compounds of 4-ethyl guaiacol (15%), hexadecanoic acid (10.6%), (E)-β-damascenone (7.8%), dihydroactinidiolide (6.0%) and 4-vinyl guaiacol (4.5%) for C. creticum and hexadecanoic acid (18.6%), hexahydrofarnesylacetone (7.8%), heptacosane (5.9%), 4-vinyl guaiacol (5.8%), pentacosane (3.8%) and eugenol (3.6%) for C. nutans. The oils were evaluated at different doses for their effect on ge…
Contribution to the flora of Asian and European countries: new national and regional vascular plant records, 2
2014
The paper presents new records for 20 vascular plant species from eight Asian and two European countries. Five taxa (Artemisia campestris, Artemisia tanacetifolia, Delphinium sajanense, Diarthron vasiculosum var. undulatum, Epilobium adenocaulon) are reported from Kazakhstan, four (Deyeuxia yanyuanensis, Poa arnoldii, Stipa gracilis, Stipa macroglossa subsp. kazachstanica) from China, three (Nepeta pamirensis, Silene bucharica, Scrophularia pamiro-alaica) from Uzbekistan, two (Epilobium nervosum, Stellaria zolotukhinii) from Mongolia, two (Oenothera deflexa, Scirpus georgianus) from Poland, one (Coronopus didymus) from Tajikistan, one (Orobanche rumseiana) from Italy, one (Stipa macroglossa…
6-Prenyloxy-7-methoxycoumarin, a coumarin-hemiterpene ether from Carduus tenuiflorus
1992
Abstract From the acetone extract of Carduus tenuiflorus , a new coumarin-hemiterpene ether was isolated, which was identified as 6-(3,3-dimethylallyloxy)-7-methoxycoumarin. The synthesis of this coumarin and that of its positional isomer 7-(3,3-dimethylallyloxy)-6-methoxycoumarin were carried out from esculetin. Two other coumarins, three lignans and three flavonoids were also isolated.
Serratula tinctoria (L.) (Dyer's savory): In vitro culture and the production of ecdysteroids and other secondary metabolites
1996
The name Serratula is derived from the Latin word serra, which means saw. It designates perennial plants of the Compositae family with medium-sized, serrated leaves and purple flowers (Loste 1937). More than 40 species have been described in Europe, North Africa, and Asia. The most common is Serratula tinctoria, also known as dyer’s savory. This species, 30 to 80 cm high, grows on all kind of soils, and is widely distributed in central and northern Europe (synonym: Carduus tinctoria, Scop; French name: serratule des teinturiers; German name: Faberscharte). In France, for example, Serratula tinctoria is widespread but with an irregular distribution, rare in the north and near the Mediterrane…
The wild taxa utilized as vegetables in Sicily (Italy): a traditional component of the Mediterranean diet
2018
Background: Wild vegetables in the Mediterranean Basin are still often consumed as a part of the diet and, in particular, there is a great tradition regarding their use in Sicily.In this study, an ethnobotanical field investigation was carried out to (a) identify the wild native taxa traditionally gathered and consumed as vegetables in Sicily, comparing the collected ethnobotanical data with those of other countries that have nominated the Mediterranean diet for inclusion in the UNESCO Representative List of the Intangible Cultural Heritage of Humanity and (b) highlight new culinary uses of these plants.Methods: Interviews were carried out in 187 towns and villages in Sicily between 2005 an…
Karyological observations on plant taxa endemic to the Balearic Islands
2007
Mitotic chromosome numbers are reported from 35 vascular plant taxa endemic to the Balearic Islands that are poorly known cytogenetically. The chromosome numbers of Chaenorhinum rodriguezii (2n = 14), Coristospermum huteri (2n = 22), Carduus ibicensis (2n = 26), Filago petro-ianii (2n = 26), Ononis crispa ssp. zschackei (2n = 30), and Ophrys bertolonii ssp. balearica (2n = 36) were determined for the first time. New chromosome numbers are reported in Pimpinella bicknellii (2n = 22), Calamintha rouyana (2n = 46), Vicia bifoliolata (2n = 14), and Teucrium asiaticum (2n = 30). A new diploid cytotype (2n = 16) was found in Ranunculus paludosus ssp. barceloi, which is restricted to populations f…
Nomenclatural synopsis of cirsium sect. Eriolepis (asteraceae) in Italy
2021
The names of the Italian taxa in Cirsium sect. Eriolepis are discussed. The accepted names are: Cirsium echinatum, C. eriophorum subsp. eriophorum, C. eriophorum subsp. spathulatum, C. ferox, C. italicum, C. lacaitae, C. lobelii, C. morisianum, C. scabrum, C. tenoreanum, C. vallis-demonii subsp. vallis-demonii, C. vallis-demonii subsp. calabrum comb. nov., and C. vulgare (= C. crinitum, C. sylvaticum). Four accepted names are typified by specimens preserved at FI (one lectotype), G (one lectotype and one neotype), P (one lectotype), and by illustrations (two lectotypes). Several other heterotypic synonyms of taxa described from Italy are discussed and six of them are typified. A new combina…
