Analysis of flavonoid in Allium cepa L., Allium sativum, Allium tuberosum, and Allium victorialis var. platyphyllum at various drying methods and processing method were investigated using HPLC. Many studies reported to have the high levels of flavonoids in onion and garlic but little information for Allium tuberosum and Allium victorialis var. platyphyllumexists on their containing flavonoids. As a result of this study, four species of Allium vegatables was identified quercetin at a RT of 25.52 min, commonly. Using various drying methods, the levels of quercetin were higher in skin part (0.89mg/ml) of Allium cepa L than different parts of other Allium vegetables at air dry. Highest quercetin content of Allium cepa L. was 50.0 mg/ml and 47.5 mg/ml at 100℃ for 5min and 60℃ for 10min, respectively. In addition, the content of quercetin in the different species and portions were higher heating treats than various drying treat.

Hazardous phytotoxic nature of cobalt and zinc oxide nanoparticles assessed using <i>Allium cepa</i>

Ghodake, Gajanan,Seo, Yeong Deuk,Lee, Dae Sung Elsevier 2011 Journal of hazardous materials Vol.186 No.1

<P><B>Abstract</B></P><P>The increasing use of nanotechnology requires the clarification of the behavior and the effects of nanoparticles (NPs) as they are released into the environment. This study was to investigate the phytotoxicity of cobalt and zinc oxide NPs using the roots of <I>Allium cepa</I> (onion bulbs) as an indicator organism. The effects of cobalt and zinc oxide NPs on the root elongation, root morphology, and cell morphology of a plant, as well as their adsorption potential, were determined through the hydroponic culturing of <I>A</I>. <I>cepa</I>. <I>A. cepa</I> roots were treated with dispersions of the cobalt and zinc oxide NPs having three different concentrations (5, 10, and 20μgml<SUP>−1</SUP>). With increasing concentrations of the NPs, the elongation of the roots was severely inhibited by both the cobalt and the zinc oxide NPs as compared to that in the control plant (untreated <I>A. cepa</I> roots). Massive adsorption of cobalt oxide NPs into the root system was responsible for the phytotoxicity. Zinc oxide NPs caused damage because of their severe accumulation in both the cellular and the chromosomal modules, thus signifying their highly hazardous phytotoxic nature.</P>

Alterations in the blood glucose, serum lipids and renal oxidative stress in diabetic rats by supplementation of onion (Allium cepa. Linn)

Bang, Mi-Ae,Kim, Hyeon-A,Cho, Young-Ja The Korean Nutrition Society 2009 Nutrition Research and Practice Vol.2 No.2

This study examined the anti-diabetic effect of onion (Allium cepa. Linn) in the streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats were divided into normal rats fed control diet or supplemented with onion powder (7% w/w) and diabetic rats fed control diet or supplemented with onion powder. Diabetes was induced by a single injection of STZ (60 mg/kg, ip) in citrate buffer. The animals were fed each of the experimental diet for 5 weeks. Blood glucose levels of rats supplemented with onion were lower than those of rats fed control diet in the diabetic rats. Onion also decreased the total serum lipid, triglyceride, and atherogenic index and increased HDL-cholesterol/total cholesterol ratio in the diabetic rats. Glutathione peroxidase, glutathione reductase and glutathione S-transferase activities were high in the diabetic rats compared to normal rats and reverted to near-control values by onion. These results indicate that onion decreased blood glucose, serum lipid levels and reduced renal oxidative stress in STZ-induced diabetic rats and this effect might exert the anti-diabetic effect of onion.

Kwak, Jung-Ho,Seo, Jeong Min,Kim, Na-Hyung,Arasu, Mariadhas Valan,Kim, Sunggil,Yoon, Moo Kyoung,Kim, Sun-Ju Elsevier 2017 Saudi journal of biological sciences Vol.24 No.6

<P><B>Abstract</B></P> <P>The aim of this study was to quantify the contents of individual quercetin glycosides in red, yellow and chartreuse onion by High Performance Liquid Chromatography (HPLC) analysis. Acid hydrolysis of individual quercetin glycosides using 6M hydrochloric acid guided to identify and separate quercetin 7,4′-diglucoside, quercetin 3-glucoside, quercetin 4′-glucoside, and quercetin. The contents of total quercetin glycosides varied extensively among three varieties (ranged from 16.10 to 103.93mg/g DW). Quercetin was the predominant compound that accounted mean 32.21mg/g DW in red onion (43.6% of the total) and 127.92mg/g DW in chartreuse onion (78.3% of the total) followed by quercetin 3-glucoside (28.83 and 24.16mg/g DW) respectively. Quercetin 3-glucoside levels were much higher in yellow onion (43.85mg/g DW) followed by quercetin 30.08mg/g DW. Quercetin 4′-glucoside documented the lowest amount that documented mean 2.4% of the total glycosides. The varied contents of glycosides present in the different onion varieties were significant.</P>

The Effect of Allium Vegetable Intake on the Redistribution of Pyridoxal 5'-phosphate Levels in Exercising Rats

Cho Youn-Ok,Yoon Mi-Kyung The Korean Nutrition Society 2005 Nutritional Sciences Vol.8 No.3

This study investigated the effect of allium vegetable intake on the storage and utilization of energy substrates before, during, and after exercise in tissues of rats. Ninety mts were fed either a control diet or a diet with added allium sativum (AS), allium cepa (AC), allium fistulosum (AF), or allium tuberosum (AT) for 4 weeks and then subdivided into 3 groups: before-exercise (BE) during-exercise (DE) after-exercise (AE). The DE group exercised on treadmill for 1 hour just before being sacrificed at the end of the 4th week of the dietary treatment Rats in the AE group were allowed to recuperate for 2 horns after being exercised like the DE group. Pyriooxal 5'-phospwe (PLP) levels were compared in plasma, liver and skeletal muscle of rats. There was no difference between AS animals and control animals in plasma PLP levels regardless of exercise. The plasma PLP levels of AC animals were higher than those of control animals before exercise but this PLP was decreased with exercise and lower than that of control animals after exercise. The plasma PLP levels of AF animals were higher than those of control animals during exercise but there was no difference before and after exercise. The plasma PLP levels of AT animals were higher than those of control animals regardless of exercise. Compared to those of control mts, the PLP levels of liver and muscle were significantly lower in AS, AC, AF and AT mts before exercise. The levels of liver PLP were significantly decreased in control mts while not changed in AS, AC, AF and AT mts during exercise. The levels of liver PLP tended to decrease in AS, AC and AF mts after exercise. The levels of muscle PLP were significantly decreased in control rats, while not changed in AS, AC and AF mts during exercise. The levels of muscle PLP were decreased in control mts but not changed in AS, AC and AF mts after exercise. Thus, it is suggested that the changes of PLP concentrations in plasma and tissues induced by exercise are affected by allium vegetable diet and demonstrated that allium vegetable intake induced an alteration in the redistribution of PLP among tissues.

Allium vegetable diet can reduce the exercise induced oxidative stress but does not alter plasma cholesterol profile in rats

Choi, Eun-Young,Cho, Youn-Ok 덕성여자대학교 대학원 2006 덕성여자대학교 대학원 논문집 Vol.8 No.-

Aims and Methods: This study investigated the effect of allium vegetable intake on the antioxidative activity and on plasma cholesterol profile during exercise in rats. Ninety rats were fed either a control diet or a diet with added allium sativum(AS), allium cepa (AC), allium fistulosum(AF), or allium tuberosum(AT) for 4 weeks and were then subdivided into 3 groups: before-exercise (BE); during-exercise (DE); after-exercise (AE). The DE group was exercised on treadmill for 1 hour just before being sacrificed. Animals in the AE group were allowed to take a rest for 2 hours after being exercised like the DE group. The antioxidative activity of the allium vegetables was evaluated with the activities of catalase in plasma and superoxide dismutase(SOD), the ratio of reduced glutathione/ oxidized glutathione (GSH/GSSG) and the level of malondialdehyde(MDA) in liver. The plasma concentrations of triglyceride(TG), total cholesterol(TC), high-density lipoprotein-cholesterol(HDL-C)) were also compared. Results: In AS, AC, AF and AT animals, the ratios of GSH/GSSG were significantly higher than those of control animals in BE and AE. The level of liver MDA was lower than that of control animal in AE. Compared to control animals, catalase activity of AS animals was higher in BE but was lower in AE while SOD activity of AS animals was lower in both BE and AE. Catalase activity of AC animals was higher in BE and DE while SOD activity of AC animals was higher in DE. There were no differences between AF and control in catalase activities regardless of exercise. There were no differences between control animals and AT animals in SOD activities regardless of exercise. Plasma cholesterol profiles were not significantly different in rats fed different allium vegetable diets. Conclusion: It is suggested that alliumvegetable diets have antioxidative activities and can reduce the oxidative stress driven from exercise in rats but does not alter plasma cholesterol profile.

Effects of Allium Vegetables on Energy Stores and Utilization in Exercising Rats

Kong, Eun-Young,Cho, Youn-Ok The Korean Society of Food Science and Nutrition 2004 Preventive Nutrition and Food Science Vol.9 No.1

This study investigated the effect of allium vegetable intake on the storage and utilization of energy substrates before, during, and after exercise in tissues of rats. Ninety rats were fed either a control diet or a diet with added Allium sativum (AS, garlic), Allium cepa (AC, onion), Allium fistulosum (AF, spring onion), or Allium tuberosum (AT, Chinese chives) for 4 weeks and were then subdivided into 3 groups: before-exercise (BE); during-exercise (DE); after-exercise (AE). The DE group was exercised on treadmill for 1 hour just before being sacrificed at the end of 4th week of the dietary treatment rats in the AE group were allowed to recuperate for 2 hours after being exercised like the DE group. The levels of glycogen (GLY), triglyceride (TG) and protein (PRO) were compared in liver and skeletal muscle. In the AS diet animals, the level of liver GLY was significantly higher than those of control animals in the BE, DE and AE groups. The level of muscle TG also tended to be higher in BE, but lower in AE than in control animals. In AC animals, the level of muscle GLY was significantly lower than those of control animals in BE, DE and AE. The level of muscle TG also tended to be higher than those of control animals in BE and DE but tended to be lower in AE. In AF animals, the level of muscle GLY was significantly lower than those of control animals in BE, DE and AE. The level of muscle TG was also significantly lower than those of control animals in BE, DE and AE groups. In AT animals, the level of muscle GLY was significantly lower than those of control animals in BE, DE and AE. These results suggest that Allium sativum diets enhance the capacity to store fuel before as well as during exercise and increases the potential to utilize the stored fuel during exercise.
