Polyphenols and Pharmacological Screening of a Monarda fistulosa L. dry Extract Based on a Hydrodistilled Residue By-Product
2021
This study aimed to determine the composition and content of polyphenols in the dry extract obtained from the hydrodistilled residue by-product of the wild bergamot (Monarda fistulosa L., Lamiaceae Martinov family) herb (MFDE) and to evaluate its safety and pharmacological properties. The total phenolic content (TPC) in the MFDE was 120.64 mg GAE/g. The high-performance liquid chromatography (HPLC) analysis showed the presence of a plethora of phenolic compounds, including hydroxycinnamic acids and flavone derivatives in the MFDE, with rosmarinic acid and luteolin-7-O-glucoside being the main components. With an IC50 value of 0.285 mg/mL, it was found to be a strong DPPH radical scavenger. …
No pārtikas produktiem izolētu E.coli virulences gēnu, serogrupu un antibiotiku jutīguma izpēte
2016
Šajā pētījumā 72 E.coli paraugiem, kas izolēti no gaļas produktiem un diedzētiem graudiem, tika noteikta vtx1, vtx2 un eaeA gēnu klātbūtne, serogrupu sadalījums un antibiotiku rezistence. 91.67% paraugi nesaturēja nevienu no virulences gēniem, 8.33% saturēja intimīna gēnu (eaeA), no tiem 2,78% saturēja arī vtx1. Serogrupēšanas rezultātā tika atklāts, ka 29,17% paraugu nav konstatētas verotoksīnus producējošas serogrupas, 44,43% tika konstatēta O121 serogrupa, 9,71% - O103, 12,50% - pašaglutinējoši, 1,39% - serogrupas O26, O145 un O142. Kopumā 35 paraugi tika izolēti no diedzētiem graudiem un sēklām, 37 - no gaļas produktiem. 85,70% paraugu, kas izolēti no diedzētiem graudiem pieder pie sero…
Comparison of essential oil components and in vitro anticancer activity in wild and cultivated Salvia verbenaca.
2015
The objectives of our research were to study the chemical composition and the in vitro anticancer effect of the essential oil of Salvia verbenaca growing in natural sites in comparison with those of cultivated (Sc) plants. The oil from wild (Sw) S. verbenaca presented hexadecanoic acid (23.1%) as the main constituent, while the oil from Sc plants contained high quantities of hexahydrofarnesyl acetone (9.7%), scarce in the natural oil (0.7%). The growth-inhibitory and proapoptotic effects of the essential oils from Sw and Sc S. verbenaca were evaluated in the human melanoma cell line M14, testing cell vitality, cell membrane integrity, genomic DNA fragmentation and caspase-3 activity. Both t…

Lotta alla mosca delle olive in olivicoltura integrata e biologica
2012
Bactrocera oleae, fitofago chiave dell’agroecosistema olivo, è presente in Italia in tutti gli areali interessati dalla coltura, tranne in alcune aree caratterizzate da maggiore altitudine dove il fattore termico non consente lo sviluppo della specie. Il dittero è fortemente legato alle temperature che del resto condizionano anche la fenologia dell’olivo; in effetti il numero di generazioni che la mosca può completare nell’anno varia da 1 fino a 4-5 in zone con temperature medie annue elevate (zone costiere e/o meridionali). La pericolosità della specie è pertanto legata al numero di generazioni e all’andamento climatico che, a seconda dell’annata e della zona, possono variare sensibilmente…
A new species of Silene sect. Dipterosperma (Caryophyllaceae) from Sicily
2012
Silene kemoniana, a new species of the section Dipterosperma from NW Sicily, is described and illustrated. It is a therophyte that occurs in mountains near Palermo, where it grows on Mesozoic limestones in xerophilous garigues. Its relationships with S. colorata and allied species are also examined. A key of the species belonging to sect. Dipterosperma is provided. Se describe e ilustra Silene kemoniana, una nueva especie del NW de Sicilia perteneciente a la sección Dipterosperma. Se trata de un terófito que habita en algunas montañas próximas a Palermo, donde crece sobre calizas mesozoicas entre matorrales mediterráneos xerófilos. Se estudian sus relaciones con S. colorata y otras especies…
Cytotaxonomical investigation on Allium paniculatum ssp. exaltatum (Alliaceae) from Cyprus.
2004
Arare Allium endemic to Cyprus island, known as A. paniculatum subsp. exaltatum, is here examined. Relevant features in its morphology, caryology and leaf anatomy emphasize the marked taxonomic isolation of this taxon and allow it to be treated as a distinct species, proposed as Allium exaltatum. It is an exaploid plant (2n=48), probably arisen out of allopolyploidy and morphologically related only to some Middle East taxa.
Diversity in the population of Brassica incana Ten. (Cruciferae) in Sicily
2014
henotipic diversity in Sicilian populations of Brassica incana Ten. (Cruciferae) is here ana- lyzed in comparison with the only one known population of B. raimondoi Sciandrello et al., taxonomic close species recently described from the coastal relief of eastern Sicily. The analysis of diagnostic characters of these two taxa does not reveal significant differences that justify a treatment at species level of the population of B. raimondoi. On this base, the authors deemed to include this taxon in the infraspecific variability of B. incana and consider most appropriate the rank of subspecies. Therefore is here proposed the establishment of the trinomial com- bination B. incana subsp. raimond…

Neotrinia gen. nov. and Pennatherum sect. nov.in Achnatherum (Poaceae: Stipeae)
2019
Stipa splendens (syn. Achnatherum splendens) has been transferred to Neotrinia (Tzvelev) M. Nobis, P. Gudkovaet A. Nowak gen. nov.as N. splendens (Trin.) M. Nobis, P. Gudkova et A. Nowak, based on a comparison of the macromorphology and lemma micromorphology of the Asian representatives of the tribe Stipeae. Lemma epidermal patterns in the examined species are presented and discussed. Additionally, a new section Pennatherum M. Nobis comprising Achnatherum pelliotii, a species recently transferred to Achnatherum from Ptilagrostis is also proposed. This taxon clearly differs from Ptilagrostis by the lemma micromorphology. The species with typical maize-like lemma micromorphological pattern is…
