Significant differences () were found among the five landraces with the highest pungency level in Aprilatica landrace. Both mixtures were left at room temperature for 15 min and filtered with Whatman filter paper (grade 1) and 10 mL of the filtrate was diluted ten times with bidistilled water. The slurry was transferred into the flask with 300 mL of distilled water and 1 μL of 2-octanol, as internal standard, and sonicated at 50 Hz for 30 minutes. The pungency of all landraces was found to be high according to pungency classification of the onion. The mobile phase was an acetonitrile-water solution (75 : 25), with a flow rate of 1.2 mL/min and a column temperature of 60°C. Traumatic chronic neuritis; Allium cepa has neuralgia of stump after amputation; burning and stinging pains. Generally, the results highlighted the growth temperature influence on the investigated quality parameters. Law, K. J. Hipwood, and P. H. Bellamy, “Non-structural carbohydrate profiles in onion bulbs influence taste preference,” in, G. Mennella, V. O. Sanaja', A. The antioxidant activity was expressed according to Albanese et al. and active principles as glycollic acid, etc. Onions are an important source of several phytonutrients as flavonoids, fructooligosaccharides (FOS), and thiosulfinates and other sulfur compounds, recognized as important elements of the Mediterranean diet [2]. The quantitative analyses were done assuming the response factors equal to the 2-octanol, used as internal standard [19]. De Ancos, C. Colina-Coca, D. Gonzalex-Pena, and C. Sanchez-Moreno, “Bioactive compounds from vegetable and fruit by-products,” in, V. Benítez, E. Mollá, M. A.

Functional benefits of quercetin include anti-inflammatory activity, antihistamine effect, allergy medication, and anticancer and antivirus activities. It is generally accepted that there is a high correlation between levels of enzymatically produced pyruvate (EPY) present in onions and the perception of pungency [12]. Other water soluble sugars (oligosaccharides of fructose, named fructans) were found by Davis et al. The quali-quantitative profile was determined by HPLC (1100, Agilent, Waldbronn, Germany) according to Cinquanta et al. One millilitre of sample was placed in a reaction tube with 1 mL of 2,4-dinitrophenyl hydrazine (DNPH) solution (0.0125% DNPH in 2 M HCl) and 1 mL of bidistilled water. The concentration of pyruvate produced by alliinase activity allows assessing the pungency of onions [12, 13]. Pharmacology: Constituents: Onion has been found to contain quercetin, fructose, quercetin-3-glucoside, isorhamnetin-4-glucoside, xylose, galactose, glucose, mannose, organosulfur compounds, allylsulfides, flavonoids, flavenols, S-alk (en)yl cysteine sulfoxides, cycloalliin, selenium, thiosulfinates, and sulfur and seleno compounds. The onion landraces were harvested at the end of the growth cycle corresponding to the ripening time and harvest month, respectively: February, March, April, May, and June. Laboratory work no. In regard to the investigation of onion volatile compounds, the volatile fraction was clearly dominated by sulfur compounds. 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. Before using Allium Cepa, inform your doctor about your current list of medications, over the counter products (e.g. Its close relatives include the garlic, scallion, shallot, leek, chive, and Chinese onion. Anti-cholesterol 4. Onion extracts in different concentrations were mixed with  M methanol solution of DPPH radical. High pungency values ranging from 9 to 14 μmol/g FW were found in all onion landraces investigated as enzymatically (alliinase) produced pyruvate (EPY). The production of the five white onion landraces was carried out using the conventional cultivation methods for this crop. The mobile phase used was (A) water/acetic acid (99 : 1, v/v) and (B) acetonitrile/acetic acid (99 : 1 v/v), with a gradient as follows: 0 min, 100% A; 6.5 min, 85% A and 15% B; 8.0 min, 80% A and 20% B; 12 min, 75% A and 25% B; 16 min, 70% A and 30% B; 25 min, 60% A and 40% B; 40 min, 60% A and 40% B. The slurry was subjected to steam distillation by a vertical steam distillation unit. 2017, Article ID 6873651, 9 pages, 2017. https://doi.org/10.1155/2017/6873651, 1Department of Industrial Engineering, University of Salerno, Via Giovanni Paolo II 132, 84084 Fisciano, Italy, 2Horticulture Research Center (CRA-ORT), Via Cavalleggeri 25, 84098 Pontecagnano Faiano, Italy, 3Institute for Microelectronics and Microsystems (IMM) of the National Council of Research (CNR), Via Pietro Castellino 111, 80131 Napoli, Italy. The antioxidant activity varied from 19.00 to 21.27 mg of extract/mL (Table 2). 4 Campus Boulevard Newtown Square, PA 19073 1-800-BOIRON-1. De Ancos, and C.

[43]. Chromatographic separation was performed on 2 μL of sample, using helium as carrying gas at constant flow of 1 mL/min. The amount of alk(en)yl-sulfenic acids (the lachrymator factor) was closely linked to the concentration of the aroma precursors: S-alkenyl cysteine sulfoxides (ACSOs). The landraces differ mainly in the bulb harvest time that is a function of the end of the growth cycle and so of the ripening time; the latter ranges from February to June. The concentration of identified phenols was calculated with external standards method. 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. Available 2C-30C, 200C, 4X-30X, 1M-100M, 30C, 200CH Raw onions (Allium cepa, Bianca di Pompei cv) were supplied by factories located in the Salerno area (Campania region, Italy). for the bioindicator Allium cepa L. of gels handled with 1% testosterone and 0.1% estradiol. Falend kinkhoestvaccin tijdens de zwangerschap, Corona (of Covid-19) homeopathisch bekeken, Het Corona virus, zo jong en nu al zo berucht…. Onion landraces were sliced in half longitudinally: 50 g was homogenized by Ultra-Turrax blender (T25, IKA Werke, Staufen, Germany) with 50 mL of distilled water for the determination of total pyruvate alliinase produced, whereas 50 g of onions was pretreated with 50 mL of 5% trichloroacetic acid solution to inactivate the alliinase in order to quantify pyruvate basal level. Other compounds, aldehydes and ketones, were found in a smaller amount ranging between 17–21% and 3–7% of the total volatile compounds, respectively, in landrace samples. Allium cepa. 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. The samples were centrifuged at 4000 rpm for 10 min and filtered through 0.45 μm syringe cellulose filter (Millipore, USA) before ion exchange chromatography analysis. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Onion (Allium cepa L.) is the most widely cultivated species of the genus Allium [1]. Among identified phenols, quercetin has an important role from a nutritional point of view. De bol van de uiplant is eetbaar. They are mainly inulin, kestose, nystose, and fructofuranosylnystose. The HPLC system was equipped with  mm (60 Å, 4 μm) carbohydrate-cartridge column (Waters, USA). In fact, the highest values were found for Aprilatica, Maggiaiola, and Giugnese without significant differences () among them. Heb je een vraag over dit artikel? The absorbance of solutions was read at 765 nm using a UV-Vis spectrophotometer (Lambda Bio 40; PerkinElmer, Waltham, MA, USA), after 2 hours of incubation in the dark. Anti-coagulant 14. A calibration curve of organic acid standards was obtained and used for quantitative analysis. Aldehydes content was different () for the five onion landraces investigated and it increased in landraces harvested from February (Febbrarese) to June (Giugnese). Chromatograms of phenols in onion samples at 280 and 350 nm (red and blue lines, resp.). The eluates were detected at 280 and 350 nm. Allium cepa. Nine out of fifteen S-compounds were di- and trisulfides and were the most numerous. The chemical composition of onion is organic sulphides, cotechol and protocatechnic acid, essential oils as allyl propyl disulphide, etc. Seven organic acids were identified and quantified in onion samples (Table 3). De ui wordt wereldwijd in de keuken gebruikt als groente en bestaat in allerlei vormen en kleuren. Bronchodilator 9. The main acids that contribute mostly to edible flesh acidity are malic (78.94–57.61 mg/100 g fw) and citric (63.32–19.70 mg/100 g fw) acids. This cultivar is actually composed of a set of locally named landraces, all sharing common shapes and colours (white-greenish flattened bulbs). The temperature program was as follows: 3 min at 40°C, first ramp at 2°C/min to 150°C, second ramp at 4°C/min to 220°C, and 10 min at 220°C. The volatile compounds were determined by GC-MS (Trace MS plus, Thermo Finnigan, USA) and by GC-FID (HP 6890, Agilent), both equipped with a capillary column (SUPELCOWAX 10; 60 m, 0.25 mm, and 0.25 μm, Supelco, USA). Herein, all onion landraces had high pungency values expressed by EPY amount, ranging from 9 to 14 μmol/g FW. 10 Laboratory of Ecotoxicology and LCA Department of Environmental Chemistry, ICT Prague Onion (Allium cepa) genotoxicity test 1. One hundred grams of edible part of onion samples was homogenized in an Ultra-Turrax blender (T25, IKA Werke, Staufen, Germany) at room temperature. 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. C than those harvested in winter. Allium Cepa Genotoxicity Test 1. Similarly, total phenols, phenols profile, and antioxidant activity increased in onion landraces harvested in spring months. Als je uien snijd krijg je ook tranende ogen en een loopneus. Also, other compounds such as organic acids and sugars can contribute to the sensory profile of onions. Analytical grade chemicals, methanol, dichloromethane, trichloroacetic acid, acetic acid, acetonitrile, sodium hydroxide, Folin-Ciocalteu reagent, gallic acid, 2,2-diphenyl-1-picrylhydrazyl (DPPH), dinitrophenyl hydrazine (DNPH), quercetin, kaempferol, 2-octanol, sodium sulfate, and ferulic and chlorogenic acids, were purchased from Sigma-Aldrich (St. Louis, MO, USA). Onion (ALLIUM CEPA) has following healing properties. Many people keep a supply of it with them if they are prone to suffering from hay fever. 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). After the incubation time, 5 mL of 0.6 M NaOH was added to the tube and allowed to stand for 5 min. Quercetin is the aglycone form of several other flavonoid glycosides such as rutin and quercitrin that are found in citrus fruits, buckwheat, and onions [35]. Flavonols are the most abundant in onions, present as their glycosides, that is, quercetin and kaempferol [5, 6], in higher concentration (280–400 mg/kg) than other vegetables (i.e., 100 mg/kg in broccoli, 50 mg/kg in apple) [7]. The least significant differences were obtained using an LSD test (). The results were in accordance with Santas et al. All c is daarvan een heel mooi voorbeeld. 100, USA) and concentrations were calculated with external standards method. Onions: a source of unique dietary flavonoids,”, G. Griffiths, L. Trueman, T.

These results were in agreement with Lanzotti [25] who proved that di- and trisulfides were the main compounds in the volatile fraction of the onion isolated by steam distillation. Anti-spasmodic 11. Onions (Allium Cepa L.) is one of the most popular seasoning in the world. The total content of volatile compounds as well as the sulfur-containing compounds inAprilatica was significantly () higher than the other landraces investigated. The DNP hydrazine derivative of pyruvate was measured using PerkinElmer Lambda 25  UV-Vis spectrometer at 420 nm. ), allergies, pre-existing diseases, and current health conditions (e.g. Allium cepa complex VSMis verpakt in een speciale sprayflacon die het gebruik van bewaarmiddelen overbodig maakt. No statistical difference () was found among the onion landraces as regards fructose, while significant differences () were found for glucose, sucrose, and the total sugar content. In fact, onions contain high levels of phenolic compounds, which have antioxidant properties besides beneficial effects against different degenerative pathologies (cardiovascular and neurological diseases, dysfunctions based on oxidative stress) [3]. The health benefits of these carbohydrates have been widely reported in the past years due to their prebiotic effect [8]. The GC injector was held at 40°C for 3 min, and the column temperature program increased up to 150°C at 2°C/min, from 150°C to 220°C at 4°C/min (held for 10 min). (2008) and Prakash et al. B.

Meld je dan aan voor onze nieuwsbrief. Homeopathie is bij klachten een middel  voorschrijven wat gelijksoortig is aan de klachten. 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. Analysis of parameters investigated was carried out on five different samples belonging to each onion group. A total of 22 compounds (Table 1) were identified in the volatile fraction of onion samples belonging to the following chemical classes: sulfur-containing compounds (S-compounds), aldehydes, and ketones. The organic phases were collected, dehydrated with anhydrous Na2SO4, filtered through Whatman filter paper, and finally concentrated using a Kuderna-Danish device. Total phenols, quantified in the onion samples, were reported in Table 2. Acute middelen zijn plantaardige of dierlijke middelen. Wil je op de hoogte blijven van het laatste nieuws over homeopathie, gezondheid en gezond leven? Ainsi, Allium vineale est formée en majorité d’allyltrisulfide (24 %) et diallyltetrasulfide (16 %) et Allium sativum (45 %) d’allyltrisulfide, (22 %) diallyldisulfide comme principaux constituants chimiques. The organic acids profile (malic, citric, succinic, pyruvic, oxalic, ascorbic, and tartaric acids) highlighted malic and citric acids in higher amounts in all landraces. Data from immobile/dead A. salina numbers after 24 h of exposure showed that the highest concentrations of testosterone (10 and 25 μg/mL) and the The analysis of variance (ANOVA) was applied to the data. Furthermore, the volatile S-compounds of Bianca di Pompei onion landraces were the typical molecules of the volatile fraction characterizing the onion’s pungent flavour [26–29]. The bioaccumulation of organosulfur compounds in onions depends on different factors but especially on the sulfur-based fertilization, the environment, and the genotype of the cultivars [14–16]. (2007) who studied quercetin in four (red, white, violet, and green) onion varieties. 3.1. Total antioxidant activity of pomegranate juice was determined by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method [22]. The higher content of di- and trisulfides than other volatile compounds in onion samples cultivated during warmer spring months was probably due to an increase of S-alkenyl cysteine sulfoxides (ACSOs), according to Randle and Coolong [31] who proved that growth temperature affected ACSOs concentration of Granex 33 onion. 'Snowball' is een zeer witte ui met een milde smaak. In fact, Febbrarese and Marzatica landraces grown and harvested in colder winter months showed lower concentrations of total volatile compounds than those found in Aprilatica, Maggiaiola, and Giugnese, which were characterized by a milder crop temperature. Het wordt bereid uit verse uien die in de zomer worden geoogst en worden fijngehakt en vermalen. Het hoofdkenmerk van All c is een waterige loopneus.

Sugars were determined by HPLC (Hewlett Packard, mod. Uien kunnen … The precursors of sulfur-containing compounds are S-alk(en)yl-L-cysteine sulfoxides (ACSOs, i.e., methiin, propiin, and isoalliin) which are hydrolysed by means of alliinase enzyme into pyruvate, ammonia, and a mixture of both volatile and nonvolatile sulfur compounds [11], after the breakage of the tissue caused by cutting, mastication, and cooking. Homeopathie: allium cepa (ui) In de klassieke homeopathie behoort allium cepa tot de acute middelen. The identification of flavonoids and anthocyanins, and their individual quantities, was determined by high-performance liquid chromatography (HPLC). Among the aldehydes, furfuraldehyde was the most abundant in all samples, and its highest content () was found in Aprilatica landrace. Uien hebben een sterke smaak en geur, die verminderen bij verhitting. The nutraceutical feature in… and A. sativum in the context of three different drying processes were assessed using metabolomics. The nutraceutical feature investigated through the total phenols, phenols profile, and antioxidant activity showed higher values for the samples harvested in spring months. These three onion landraces showed a concentration of volatile compounds almost five times higher than that in Febbrarese and Marzatica. (2007) who evaluated white Spanish and red, violet, and green onion varieties, respectively. The resulting mixture was homogenized and stirred for 30 minutes; homogenates were held for 15 min in an ultrasonic bath (Fungilab Ultrasound, Barcelona, Spain) and the extract was separated from the residue by centrifugation at 1900 ×g. The butyrolactone compound was detected only in landraces harvested in spring months (Aprilatica, Maggiaiola, and Giugnese). Chemistry of Allium cepa A. cepa is the source of various biologically active compounds, such as phenolic acids, thiosulfinates, and flavonoids. 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.
