Volatile and semivolatile components of 11 wild edible mushrooms, Suillus bellini, luteus, granulatus, Tricholomopsis rutilans, Hygrophorus agathosmus, Amanita rubescens, Russula cyanoxantha, Boletus edulis, Tricholoma equestre, Fistulina hepatica, Cantharellus cibarius, were determined by headspace solid-phase microextraction (HS-SPME) liquid extraction combined with gas chromatography-mass spectrometry (GC-MS). Fifty volatiles nonvolatiles formally identified 13 others tentatively...
Latex is a sticky emulsion that exudes upon damage from specialized canals several plants. It contains biologically active compounds, such as phytosterols, fatty acids, and amino acids. In plants, these compounds are involved in the interaction between insects, environment. Despite its chemical, biological, ecological importance, Ficus carica latex still poorly studied. To improve knowledge on metabolite profile of this matrix, targeted analysis was performed representative sample F. latex....
The phenolic profile of barley (Hordeum vulgare L.) leaves, seeds, awns, and stems, collected in two different locations from Portugal, was determined by a high-performance liquid chromatography/diode array detector (HPLC/DAD). A total 28 compounds were identified quantified, which included 4 acids, 6 C-glycosylflavones, 18 O-glycosyl-C-glycosyl flavones, with some them acylated. Distinct profiles noticed among the analyzed materials. greatest diversity found leaves (26 flavonoids 2 acid...
Capsella bursa-pastoris (L.) Medik. (Brassicaceae) is a wild herb with high nutritional value that can be eaten raw or cooked. A metabolomic study was performed different extracts of its aerial parts were tested concerning their antiradical, acetylcholinesterase inhibitory and antibacterial activities. Phenolic compounds identified quantified by HPLC-DAD, organic acids amino determined HPLC-UV, while free fatty sterols analysed GC-ITMS. The vegetal material rich in kaempferol-3-O-rutinoside...
Underwater acoustic networks can be quite effective to establish communication links between autonomous underwater vehicles (AUVs) and other or control units, enabling complex vehicle applications scenarios. A communications framework support the use of sample application scenarios are described for single multi-AUV operation.
Colocasia esculenta (L.) Shott, commonly called taro, is an ancient species selected for its edible tuber. Its huge "elephant ear" like leaves are also consumed in sauces and stews or as soups. Forty-one phenolic metabolites (11 hydroxycinnamic acid derivatives 30 glycosylated flavonoids) were identified by high-performance liquid chromatography-diode array detection-electrospray ionization/mass spectrometry (HPLC-DAD-ESI/MS(n)) the of two C. varieties cultivated Azores Islands. To our...
Tamarix aphylla (L.) Karst. has a wide geographic distribution and was employed in traditional medicine as astringent, anti-rheumatic to treat fever. T. leaves stems extracts were studied from both chemical biological points of view assess the antidiabetic, anticholinesterase antioxidant potential this species. The HPLC/Diode Array Detector (DAD) analysis showed presence 14 phenolic compounds (gallic, caffeic, p-coumaric, ferulic ellagic acids, kaempferol, quercetin, quercetin...
Volatile and semi-volatile components of internal external leaves Brassica oleracea L. var. costata DC, grown under different fertilization regimens, were determined by headspace solid-phase microextraction (HS-SPME) combined with gas chromatography/ion trap mass spectrometry (GC/ITMS). Forty-one volatiles non-volatile formally identified thirty others tentatively identified. Qualitative quantitative differences noticed between leaves. In general, exhibited more aldehydes sulfur volatile...
Abstract Piper betle is a species growing in South East Asia, where its leaves are economically and medicinally important. To screen the highest possible number of volatile semivolatile components, were subjected to headspace solid‐phase microextraction, hydrodistillation Soxhlet extraction, prior analysis by GC/MS. Fifty compounds (identified comparison with standard or tentatively National Institute Standards Technology database) determined, 23 being described for first time this matrix....
Zinc tolerance, accumulation, and organic acid production by Solanum nigrum, a known Zn accumulator, was studied during pre- post-flowering stages of development. The plants, when challenged with concentrations lethal to plantlets, showed an increase in tolerance from pre-flowering post-flowering, which accompanied reduction translocation the aerial plant parts. Treatment induced differential response acids according organ developmental stage. In roots, where were similar general decrease...
The need of new anti-inflammatory drugs has led to the search for safer and more potent molecules in distinct sources, such as natural products. This work aimed explore potential aqueous extracts from two herbal teas (Annona muricata L. Jasminum grandiflorum L.) RAW 264.7 macrophages cells cell-free assays. Furthermore, phenolic composition both their hydrolysates was characterized by HPLC-DAD, order establish possible relationships with biological activity. In a general way, A. displayed...
This paper presents the Mission Review and Analysis module of a C3I (Command, Control, Communication Information) infrastructure - Neptus framework. is mix-initiative environment that it's being developed in Underwater Systems Technology Laboratory (USTL/LSTS) with goal to support coordinated operation heterogeneous teams vehicles. includes autonomous remotely operated underwater, surface, land, air vehicles people. People perform fundamental role, not only case vehicles, but also where...
