Onion (Allium Cepa) contains high levels of flavonoids. Although there are many studies indicating the inhibitory effects of flavonoids on xanthine oxidase, there is no report on the effect of onion on this enzyme. Therefore, in the present study, the inhibitory effects of onion on xanthine oxidase are investigated. Fresh filtered juice of onion was prepared and its inhibitory effect on guine...

Onion (Allium cepa) is being studied as a potential anticancer agent, but little is known regarding its effect in multidrug resistance (MDR) cells. In this work, the cytotoxicity of crude onion extract (OE) and fractioned extract (aqueous, methanolic and ethyl acetate), as well as some onion compounds (quercetin and propyl disulfide) were evaluated in Lucena MDR human erythroleukemic and its K5...

Increasing onion yield and improving bulb quality are essential aims for growers to fulfill the requirements of the market and the consumers. Two field experiments were carried out during two successive seasons; 2011/2012 and 2012/2013 at the experimental station of National Research Centre, Beheira Governorate (North of Egypt) to find out the influence of some bio-stimulants i.e., yeast extrac...

Background. Onion extracts have been shown in vitro to accelerate wound healing. Results from clinical studies on surgical scars in Caucasians were disappointing. The aim of this study is to evaluate the effectiveness of onion extract gel in improving the cosmetic and symptoms of surgical scars in Asians. Patients/Methods. Twenty Asians who had new Pfannenstiel's cesarean section scars were rec...

This study was performed to investigate the inhibitory effect of green onion produced in Korea on the growth of A. parasiticus, a toxigenic strain. The effect was studied using different concentrations of freeze-dried green onion in solid culture with potato-dextrose agar (PDA) or in liquid culture with yeast-extract sucrose (YES) broth at 25°C for 15 days. The addition of green onion to the me...

this study was carried out to evaluate the effects of red onion (allium cepa l.) juice and green tea (camellia sinenses) extract on lipid oxidation and sensory characteristics of refrigerated (4ºc) sturgeon fillets (acipenser persicus). fresh fillets were tumbled in 1%, 2.5%, and 5% (v/v) aqueous solutions of onion juice (oj) and tea extract (te), and then stored for up to 8 days at 4°c in a re...

The Effect of tincture of Tinospora cordifolia was evaluated using onion root tip mitosis as the test system. The aqueous extract stimulated the mitotic activity significatory.

Objectives: This study aimed to investigate the estrogen-like activities of the outer scales of onion and garlic. Methods: This work compared the estrogenic effects induced by estradiol and the plant extract in vivo and in vitro models of immature mice. Uterine wet weight/body weight ratios were determined. Uterotrophic bioassay (increased epithelial cell height, and gland development), immunoh...

BACKGROUND A common question asked by patients who are healing from a surgical incision is, “What is the best product to use to minimize a scar?” Commercially, the many topical products on the market make it difficult to decide what is the best product to recommend. Each product claims to have its advantages in reducing scarring with its combination of ingredients. Often, many of these products...

We investigated the suppressive effects of Welsh onion (Allium fistulosum L.) on the hyper-production of mucins in NCI-H292 human lung cancer cells. Periodic acid-Schiff staining showed that the 50% (v/v) ethanol extract of Welsh onion suppressed mucus glycoprotein production in cells, whereas the water and ethanol extracts did not. A real-time RT-PCR analysis demonstrated that the 50% ethanol ...
