Data from: Effects of undergrowth removal and edge proximity on ground beetles and vascular plants in urban boreal forests

2019

Urban forests are regularly managed for human safety and aesthetic reasons, but they are crucial habitat for many species. Removals of undergrowth occur commonly in these forests, yet the ecological consequences of these operations are poorly understood. We sampled ground beetles (Coleoptera, Carabidae) and vascular plants along 20-m edge gradients in Finnish urban forests, in five stands treated 0.5−2.5 years earlier with undergrowth removal and in five untreated stands. We hypothesized that undergrowth removal and edge proximity would benefit opportunistic and open-habitat species, whereas shady-habitat species would be affected negatively. (1) Regarding carabids, diversity and evenness i…

Gestione ecocompatibile delle infestanti nel finocchio da seme (Foeniculum vulgare Mill.)

2009

Nelle coltivazioni officinali, l'adozione di tecniche a basso impatto ambientale (tra cui la produzione in regime di agricoltura biologica) costituisce una scelta quasi obbligata per consentire al prodotto un'adeguata competitività sui mercati nazionali ed esteri. In quest'ambito, gli evidenti effetti che le infestanti esercitano sulla produzione e sui suoi parametri qualitativi pongono la gestione delle infestanti tra i principali nodi dell'agrotecnica delle colture officinali. Nel quadriennio 2004 -2007, il DAAT dell'Università di Palermo ha pertanto svolto una serie di sperimentazioni in campo tendenti a verificare l'efficacia contenitiva e gli effetti sulla coltura di alcune tecniche di…

Influence of enzyme-aided extraction and ultrasonication on the phenolics content and antioxidant activity of Paeonia officinalis L. petals

2020

Peony is a less utilized herbaceous plant of ornamental and medicinal relevance. The petals are rich in bioactive phenolics and hence, the development of efficient extraction is required for maximum recovery and bioactivity. In this study, the optimal conditions for the ultrasound-assisted extraction of peony phenolics were first investigated by comparing to conventional extraction and testing the data fit by mathematical models (linear, two factor interactions, quadratic) followed by investigation of cellulase pre-treatment combined with ultrasonication. High amounts of flavonoids, phenolics and tannins were extracted in 30 min under ultrasound conditions of 150 W, 40 kHz, 50 % amplitude, …

Natural products for the treatment of Type 2 Diabetes Mellitus

2015

Type 2 diabetes mellitus is a metabolic disease characterized by persistent hyperglycemia. High blood sugar can produce long-term complications such as cardiovascular and renal disorders, retinopathy, and poor blood flow. Its development can be prevented or delayed in people with impaired glucose tolerance by implementing lifestyle changes or the use of therapeutic agents. Some of these drugs have been obtained from plants or have a microbial origin, such as galegine isolated from Galega officinalis, which has a great similarity to the antidiabetic drug metformin. Picnogenol, acarbose, miglitol, and voglibose are other antidiabetic products of natural origin. This review compiles the princi…

Genetic variation and evolutionary analysis of Cucumber mosaic virus in medicinal, aromatic and ornamental plants from Northern Italy

2011

The genetic variation and evolution of Cucumber mosaic virus (CMV) (1) infecting aromatic, medicinal and ornamental plants in Northern Italy were studied by sequence analysis of the movement protein gene and comparison with equivalent sequences of isolates from other countries. Comparison of nonsynonymous and synonymous substitutions at each codon suggested that 30% of amino acid sites were under negative selection and only one was under positive selection. Phylogenetic inference, nucleotide diversity estimation, neutrality tests and genetic differentiation analysis revealed a high nucleotide diversity of CMV in Northern Italy with respect to areas of other countries [1,2] and suggested tha…

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…

Chemical composition and anticancer activity of essential oils of Mediterranean sage (Salvia officinalis L.) grown in different environmental conditi…

2013

Salvia officinalis L. can be found worldwide and its leaves are commonly used as ingredient in food industry. Sage essential oil is applied in the treatment of a range of diseases and has been shown to possess different biological activities. The objectives of our research were to study the effects of environment on crop, chemical composition and anticancer activity on S. officinalis essential oil. Sage was cultivated at eighteen experimental sites in south-central Italy (Molise) in different growing environments. The essential oils (S1-S18), extracted by hydrodistillation, were analyzed by GC and CG/MS. Results show that the main components were α-thujone, camphor, borneol, γ-muurolene and…

Prove di coltivazione di Calendula (Calendula officinalis L.) in ambiente semi-arido

2008

Inside the family Asteraceae, Marigold is one of the most relevant species bearing some herbal interest. The evaluation of the bio-agronomical and yield response of the species to the field cropping conditions, especially when a low input cropping technique is applied, is the base for its full exploitation. With this objective, a long-term research activity has been started out by the DAAT (Department of Environmental and Land Agronomy) of the University of Palermo in the experimental farm “Sparacia” (Cammarata – AG – Sicily), performing observations on Marigold plants managed with a minimum recourse to external technical inputs (nor pesticides neither chemical weeding, and a light (50 kg h…
