2012
Troia, Angelo, Greuter, Werner, Raimondo, Francesco Maria (2012): Revised lectotypification of the name Calendula maritima (Asteraceae). Phytotaxa 71 (1): 48-51, DOI: 10.11646/phytotaxa.71.1.9, URL: http://biotaxa.org/Phytotaxa/article/view/phytotaxa.71.1.9
Disegni botanici di Angelina Damiani Lanza (1879 - 1936)
2017
Botanical drawings of Angelina Damiani Lanza (1879 - 1936). The drawings of Sicilian plants made by Ange- lina Damiani are reported and commented. After a brief presentation of the author’s personality, the technique used in the drawings is examined, together with the relevant value from the artistic and botanical point of view. This material, mainly consisting of pencil drawings gathered in an album recently donated to the Director of the Palermo Botanical Garden, sin- ce 2006 is exhibited in the small historical museum set up in one of the halls of the monumental Gymnasium of the same Botanical Garden. Most of the drawings done by Angelina Damiani for the studies of her husband, the Sicil…
Inflorescence scents of Calendula maritima, C. suffruticosa subsp. fulgida, and their hybrid
2018
Premise of research. Hybridization is an important driver of plant evolutionary processes. By attracting the same pollinators to different species, floral scents may be involved in the formation of hybrids and breakdown of species boundaries. In contrast, by attracting a different suite of pollinators to hybrids and their parents, floral scents are believed to contribute to speciation processes initiated by hybridization events. Scents may or may not differ between the hybrids and their parents, but little is known about the scent chemistry of parental species and their hybrids. Methodology. We studied the inflorescence scents of parental Calendula maritima and C. suffruticosa subsp. fulgid…
Characterizing the effects of salt stress in Calendula officinalis L
2017
In this study the effects of salt stress on growth and several stress markers were investigated in the ornamental and medicinal plant Calendula officinalis. One month old plants were submitted to increasing concentrations of salt up to 150mM NaCl for a period of 30 days. Salinity affected growth in terms of stem length and fresh weight of the plants, but water content remained unchanged indicating a certain tolerance to low and mild concentrations of salt. Although Na+ and Cl− increased in parallel to applied salt treatments, the levels of K+ and Ca2+ showed no significant change, while Mg2+ levels recorded a two folds increase upon the application of the highest salt concentration. Other m…
PROVE DI COLTIVAZIONE DI COMPOSITE DI INTERESSE OFFICINALE IN AMBIENTE SEMI-ARIDO.
2009
All’interno della flora officinale mediterranea, le Composite assumono un ruolo di primaria importanza. Nella sola Sicilia, esse rappresentano circa il 19 % del totale delle specie spontanee considerate di maggior interesse erboristico, costituendo la famiglia a diffusione più ampia. Alcune delle essenze più significative sono senza dubbio la Calendula (Calendula officinalis L.), il Partenio (Tanacetum parthenium L.) e il Cardo mariano (Silybum marianum Gaertn.). Prospettive estremamente interessanti appaiono inoltre collegate all’introduzione di Composite alloctone dotate di forti potenzialità agroindustriali, tra le quali ad esempio il Piretro (Chrisanthemum cinerariaefolium (Trev) Bocc.)…
HPLC Determination of Polyphenols from Calendula officinalis L. Flowers
2017
Abstract Romanian spontaneous flora provides a lot of resources for the determination of different chemical compounds. This study uses flower samples from Calendula officinalis L. extracted through maceration. The chemical compounds determined were: (+)-catechin, caffeic acid, chlorogenic acid, cinnamic acid, ferulic acid, gallic acid, rutin, resveratrol and quercetin. They were analyzed by using an optimized HPLC method. (+)-Catechin, caffeic acid, chlorogenic acid and quercetin could not be identified in the analyzed samples. The greatest amount of phenolic compound found was rutin and the smallest quantity was determined for ferulic acid. The quantified compounds have proven to have bene…
Investigation of the biological activities of Calendula officinalis L. products
2016
Ārstniecības kliņģerītes ir vienas no senākajiem un pazīstamākajiem ārstniecības augiem pasaulē. Tās ir ātraudzīgas un jau vēsturiski plaši izmantotas tautas medicīnā. Pētījumi par ārstniecības kliņģerīšu lomu veselības saglabāšanā un stiprināšanā, izvērtējot aktīvo vielu saturu un sastāvu tajās, tās var pozitīvi ietekmēt cilvēka organismu gan profilakses nolūkos, gan kā papildus terapija ārstēšanas brīdī. Maģistra darba mērķis bija noskaidrot, kādas un cik daudz aktīvās vielas atrodamas pašgatavotos un aptiekā nopērkamos produktos. Pētījumā tika izmantoti 5 pašu pagatavoti ārstniecības kliņģerītes paraugi un 1 aptiekā iegādāts paraugs, no kuriem tika iegūti 6 analīžu paraugi, kas analizēti…
Distribuzione, fenologia e status di conservazione di Calendula suffruticosa Vahl subsp. maritima (Guss.) Maikle (Asteraceae)
2008
La coltivazione della calendula (Calendula officinalis L.) come prodotto erboristico.
2009
All’interno della flora officinale mediterranea, la famiglia delle Asteracee (ex Composite) assume un ruolo di primaria importanza, comprendendo circa il 19% del totale delle specie di interesse erboristico censite in Sicilia. Tra queste, molto rappresentata è la calendula (Calendula officinalis L.), la cui droga è tradizionalmente costituita dai capolini, di un acceso colore arancione, che vengono largamente adoperati, da soli o in miscela con altri derivati vegetali, in erboristeria e dall’industria farmaco-cosmetica. Le proprietà attribuite alla specie sono numerose e assai diversificate: oltre alle note e tradizionalmente utilizzate azioni antiinfiammatoria, cicatrizzante, emolliente ed…
