allium cepa composition
The presence of an extra chromosome of A. cepa obviously increases the nuclear DNA amount above the A. fistulosum value but also alters the apparent mean GC content. Traumatic chronic neuritis; Allium cepa has neuralgia of stump after amputation; burning and stinging pains. (2007) who studied quercetin in four (red, white, violet, and green) onion varieties. Uien worden in vele gerechten gebruikt. Purpose The Allium cepa assay is an efficient test for chemical screening and in situ monitoring for genotoxicity of environmental contaminants. and A. sativum in the context of three different drying processes were assessed using metabolomics. Organic acids (mg/100âgâfw; mean Â± SD), sugars (g/100âgâfw; mean Â± SD) content, and pungency (, Chemical Composition and Antioxidant Properties of Five White Onion (, Department of Industrial Engineering, University of Salerno, Via Giovanni Paolo II 132, 84084 Fisciano, Italy, Horticulture Research Center (CRA-ORT), Via Cavalleggeri 25, 84098 Pontecagnano Faiano, Italy, Institute for Microelectronics and Microsystems (IMM) of the National Council of Research (CNR), Via Pietro Castellino 111, 80131 Napoli, Italy, Different letters (a, b, c, etc.) Expectorant 10. Allium cepa complex VSMis verpakt in een speciale sprayflacon die het gebruik van bewaarmiddelen overbodig maakt. Seven organic acids were identified and quantified in onion samples (Table 3). The eluates were detected at 280 and 350ânm. 79852, USA) . About the aldehydes class, four compounds were detected in the volatile pattern of onion samples except for 2-methyl-2-pentenal which was not detected in Febbrarese landrace. In fact, the highest values were found for Aprilatica, Maggiaiola, and Giugnese without significant differences () among them. The GC injector was held at 40Â°C for 3âmin, and the column temperature program increased up to 150Â°C at 2Â°C/min, from 150Â°C to 220Â°C at 4Â°C/min (held for 10âmin). Malic acid was the most abundant organic acid for all onion samples except for Febbrarese landrace, where citric acid was the abundant organic acid. De ui (Allium cepa), of tuinui, in Zuid-Nederland en Vlaanderen ook wel ajuin of juin genoemd, en in Noord-Nederland siepel, is een plant uit de narcisfamilie. The analysis of variance (ANOVA) was applied to the data. Chromatographic separation was performed on 2âÎ¼L of sample, using helium as carrying gas at constant flow of 1âmL/min. Detector and transfer line were held at 250Â°C. A similar result has been documented by Arnault et al. The overall content of volatile compounds seems to be influenced by growth cycle and harvest month which is a function of temperature. The results were in accordance with those found in Recas cv onions , in four onion Greek cvs , and in six onion Spanish cvs  with fumaric and glutamic acids too. vitamins, herbal supplements, etc. (2007) who evaluated white Spanish and red, violet, and green onion varieties, respectively. Anti-inflammatory 3. White onion landraces were harvested at the end of the growth cycle and classified according to the harvest month: Febbrarese, Marzatica, Aprilatica, Maggiaiola, and Giugnese reaped in February, March, April, May, and June, respectively. Here, we report a comparative study of the phytochemical profile and the biological activity of two onion extracts, namely Allium cepa L. and Allium × cornutum (Clementi ex Visiani 1842), members of the family Amaryllidaceae. The resulting mixture was homogenized and stirred for 30 minutes; homogenates were held for 15âmin in an ultrasonic bath (Fungilab Ultrasound, Barcelona, Spain) and the extract was separated from the residue by centrifugation at 1900âÃg. D. Albanese, L. Cinquanta, G. Cuccurullo, and M. Di Matteo, âEffects of microwave and hot-air drying methods on colour, L. Liguori, P. Russo, D. Albanese, and M. Di Matteo, âEvolution of quality parameters during red wine dealcoholization by osmotic distillation,â, V. Lanzotti, âThe analysis of onion and garlic,â, C. Colina-Coca, D. González-Peña, E. Vega, B. The slurry was subjected to steam distillation by a vertical steam distillation unit. Cepa Sectio: A. sect. 3.1. The total content of soluble sugars in Bianca di Pompei landraces changed from 3 to 5âg/100âgâFW according to the ranges reported in the literature for other onion cultivars [38â42]. Uien hebben een sterke smaak en geur, die verminderen bij verhitting.

The 1,2-cyclopentanedione concentration differed at harvest time: in spring months, Aprilatica, Maggiaiola, and Giugnese landraces had a higher content () than those yielded in winter (Febbrarese and Marzatica). Furthermore, they have also protective effects against cardiovascular diseases. The purpose of this study was to examine the chemical composition of cell walls from the papery scales and outer fleshy scales of onion (Allium cepa L. cv. For all the investigated onion landraces, quantitative analysis showed that di- and trisulfides, such as cis- and trans-methyl-1-propenyl disulfide, methyl-2-propenyl disulfide, dipropyl disulfide, cis- and trans-propenyl propyl disulfide, methyl propyl trisulfide, and dipropyl trisulfide, were the largest part, whose sum represents about 60% of S-compounds. . and active principles as glycollic acid, etc. The aim of this paper was to characterize different onion landraces belonging to Bianca di Pompei cv in terms of main quality parameters for this crop (volatile compounds, organic acids, sugars, polyphenols, antioxidant activity, and pungency). The antioxidant activity was expressed according to Albanese et al. Allium cepa (onion) bulbs are used as spice in the preparation of virtually all meals in Nigeria, and some researchers had reported its medicinal values. All the other phenols increased in landraces harvested in spring months. Heb je een vraag over dit artikel? The plant portion commonly used is the bulb, which is utilized as a food ingredient to give flavour and aroma to a great variety of dishes. The organic acids profile (malic, citric, succinic, pyruvic, oxalic, ascorbic, and tartaric acids) highlighted malic and citric acids in higher amounts in all landraces. Cholesterol: wat is het en hoe ga je er mee om? The butyrolactone compound was detected only in landraces harvested in spring months (Aprilatica, Maggiaiola, and Giugnese). Environmental Contamination 138 The mitotic index and replication index are used as indicators of adequate cell proliferation (Gadano et al., 2002), which can be measured by the plant test system Allium cepa. The free radical scavenging activity determined by DPPH was expressed as the EC50 value: mg of the extract per mL required to reduce 50% of the initial DPPH radical activity. Allium cepa is a homeopathic remedy made from red onions that is commonly used to relieve the symptoms of hay fever, nasal congestion, or similar complaints.It is a popular remedy and may easily be obtained from a pharmacy that carries a range of homeopathic medicines. Cell-wall material (CWM) was prepared from the component tissues and analyzed for its carbohydrate and phenolic composition. A. cepa differs significantly from A. fistulosum in genome size (2C DNA = 33.2 pg in A. cepa and 23.3 pg in A. fistulosum) as well as in GC content (38.7% and 39.8%, respectively). (2007) in the characterization of different onion cvs cultivated in the United Kingdom. . 4 Campus Boulevard Newtown Square, PA 19073 1-800-BOIRON-1. De bol van de uiplant is eetbaar. Ze worden voorgeschreven in acute situaties of bij acute aandoeningen. The samples were centrifuged at 4000ârpm for 10âmin and filtered through 0.45âÎ¼m syringe cellulose filter (Millipore, USA) before ion exchange chromatography analysis. B. Tomsett, D. O'Connor, and M. G. Jones, âAssessment of the flavour of fresh uncooked onions by taste-panels and analysis of flavour precursors, pyruvate and sugars,â, G. Caruso, S. Conti, G. Villari et al., âEffects of transplanting time and plant density on yield, quality and antioxidant content of onion (. The onion landraces were also studied for their specific phenols composition (Figure 1 and Table 2). 100, USA) and concentrations were calculated with external standards method. Onions (Allium Cepa L.) is one of the most popular seasoning in the world. Anti-cancer 6. This research was financially supported by âMinistero dellâIstruzione, dellâUniversitÃ e della Ricercaâ and Regione Campania as part of project âAGRIGENETâNetwork per la Salvaguardia e la Gestione delle Risorse Genetiche Agro-Alimentari Campaneâ (PSR 2007â2013, Misura 214). Total antioxidant activity of pomegranate juice was determined by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method . Both mixtures were left at room temperature for 15âmin and filtered with Whatman filter paper (grade 1) and 10âmL of the filtrate was diluted ten times with bidistilled water. The extracts were redissolved in 10âmL of methanol  and were used for the determination of polyphenols and antioxidant activity.
