The aim of this study was to characterize the phenolic composition and evaluate bioactivity several samples Lavandula pedunculata (Mill.) Cav, compare aqueous hydroethanolic extracts. Plant materials were obtained by growing some accessions (seed samples) various wild populations from different regions Portugal conserved at Portuguese Genebank in Braga. Phenolic compounds analised HPLC-DAD-ESI/MSn, antioxidant potential through vitro assays (DPPH radical scavenging activity, reducing power...
This study aimed to analyse the chemical profile and biological activities of 29 accessions Brassica rapa (turnips) 9 napus (turnips seeds) collections, maintained ex situ in Portugal. HPLC-HRMS allowed determination glucosinolates (GLS) polyphenolic compounds. The antioxidant antimicrobial were determined by using relevant assays. profiles showed that glucosamine, gluconasturtiin, neoglucobrassin most abundant GLS extracts from turnip accessions. Minor forms include gluconapoleiferin,...
Oregano (Origanum vulgare L.) and thyme (Thymus mastichina are popular aromatic plants used in the culinary sphere known for their antioxidant capacity. This study investigates variability capacity phenolic profiles, focusing on flavonoids acids, of oregano accessions from Portuguese Bank Plant Germplasm. The was assessed by measurements using ferric-ion-reducing power DPPH radical scavenging activity assays, Total Phenolic Content, individual compounds. extracts presented highest total...
The main goal of this work was to study the genetic erosion risk plants with aromatic, medicinal and gastronomic applications in Portugal, particularly Alentejo region. target species were coriander (Coriandrum sativum L.), hart's pennyroyal (Mentha cervina L.) pulegium L.). methodology involved direct observations surveys (2002/2003 2011). GE formula applied Hammer's studies used estimate erosion. factors causing primary drivers biodiversity loss: habitat loss, invasive species,...
Coriandrum sativum L. and Foeniculum vulgare Mill. are two aromatic medicinal Apiaceae species commonly grown in Portugal, whose essential oils (EOs) used the food, pharmaceutical, cosmetics industries. The present study evaluated EOs isolated from fruits vegetative aerial parts (VAPs) of 11 samples 19 plant material was experimental fields, after collection several regions mainland Portugal. were by hydrodistillation analyzed gas chromatography chromatography-mass spectrometry. coriander...
Coriander is a medicinal and aromatic plant (MAP) traditionally cultivated used in Alentejo, Portugal. However, few publications are available about its ethnobotanical applications. Four independent surveys were carried out: throughout the region (2002–2003), three villages (2013), city markets (2007 2022). was most common fresh MAP (75% of total area) also representative herb markets. The leaves, mostly, or frozen transformed piso. Some recipes have agro-industrial potential, such as piso...
Origanum vulgare L. is a well-known aromatic and medicinal plant, whose essential oil (EO) has recognised flavouring properties. In this study, subsp. virens (Hoffmanns. & Link) Ietsw. EOs, isolated from accessions grown in experimental fields, were evaluated. The plant material was rooted cuttings or nutlets (fruits), originally collected 20 regions mainland Portugal harvesting for EO isolation performed two years. EOs by hydrodistillation analysed gas chromatography chromatography-mass...
Genebanks and other ex situ collections have a significant role in the conservation, management use of crop genetic diversity, including that wild relatives.Efficient depends on insight into patterning distribution diversity as well obtaining baseline information phenotypic characters traits.Wild carrot (Daucus carota L.) is closest relative cultivated L. subsp.sativus (Hoffm.)Arcang.), potential source useful traits for improvement.There are over 900 accessions D. described European...
Abstract One hundred accessions of a “core collection” Diplotaxis tenuifolia (L.) DC. and Eruca spp. were screened at seedling stage for resistance to downy mildew. Accessions tested the assigned 0–6 interaction phenotypes. All cultivated rocket ( spp.) exhibited resistant (R) response both in cotyledons young leaves. The wild D. ) higher susceptibility than 1st 2nd leaves, with 16 47 classified as or partially (PR) cotyledon leaves stages, respectively. Only three displayed an R phenotype...
The Vaccinium genus contains about 500 species distributed worldwide but only a limited number of have been studied for genetic diversity using molecular markers. In this study, analysis was conducted on three (four cultivars V. corymbosum, four wild populations myrtillus, and two ashei), total 95 genotypes, eight microsatellite (SSR) loci. A 57 alleles were detected. per locus ranged from 2 to 14, with an average 7.25. Six unique in ashei, myrtillus identified as being potential dendrogram...
