Phase II xenobiotic metabolizing enzymes confer amelioration of risk arising from potentially carcinogenic chemicals derived both endogenously, and exogenously, from food and the environment. In this study, efforts were made to isolate and identify potentially cancer preventive constituents from

Newly identified bicyclic sulfoxides, welsonins A1 (1) and A2 (2), were isolated from acetone extracts of the bulbs of the Welsh onion (Allium fistulosum). In this study, the structures of 1 and 2, which are tetrahydrothiophene-S-oxide derivatives, were characterized by spectroscopic analysis. These

Bunching onion [Allium fistulosum L. (Liliaceae)] secretes mucus in the cavities of its green leaves. The effects of the mucus, which is consumed as food, were examined. The mucus augmented the production of tumor necrosis factor (TNF)-α and monocyte chemotactic protein (MCP)-1 from RAW 264 cells

In this study, the new stable sulfur-containing compounds onionins A2 (1) and A3 (2) were isolated from the acetone extracts of the bulbs of Allium cepa L. and identified as the stereoisomers of onionin A1 discovered in our previous study. Their chemical structures,

Colorectal cancer is a common malignancy and a leading cause of cancer death worldwide. Diet is known to play an important role in the etiology of colon cancer and dietary chemoprevention is receiving increasing attention for prevention and/or alternative treatment of colon cancers. Allium

We succeeded in purifying the fraction containing the major glycolipids in monogalactosyl diacylglycerol, digalactosyl diacylglycerol and sulfoquinovosyl diacylglycerol (SQDG) from dried vegetables. This glycolipids fraction was an inhibitor of DNA polymerase alpha (pol alpha) in vitro and also the

The anti-inflammatory effects of an aqueous extract of Welsh onion green leaves (WOE) in mice was investigated. Administration of WOE, in the range of 0.25-1g/kg, showed a concentration dependent inhibition on paw edema development after carrageenan treatment in mice. The anti-inflammatory effects

The objective of the study was to isolate and identify potential cancer preventive constituents from green onion based on the ability to induce quinone reductase (QR, a representative phase II enzyme) in murine hepatoma cells (Hepa 1c1c7). Crude nonpolar solvent extracts were prepared from

Rice porridge containing Allium fistulosum (Welsh onion) root water extract (RAFR) has anti-inflammatory bioactive compounds. We examined whether the long-term administration of rice porridge with RAFR would prevent or delay the progression of osteoarthritis and menopausal symptoms in

To study the relation between allium vegetable intake and cancer of the esophagus (EC) and stomach (SC) in Yangzhong city, which is one of the highest-risk areas for these cancers in Jiangsu province, China, a simultaneous case-referent study was conducted using histopathologically confirmed cases

The present study investigated the effects of quercetin glucosides, which were isolated from the Chinese onion (Allium chinense), garlic (Allium sativum), onion (Allium cepa L.) and the Welsh onion (Allium fistulosum L.) in HepG2, HT-29 and PC-3 cancer cell lines. Quercetin-3,4'-di-O-glucoside

Many studies have found links between diet and cancer. The summary estimates of the association between dietary factors and cancer risk were investigated using previously reported studies of the Korean population. Gastric cancer risk was inversely associated with the high intake of soy foods [OR

OBJECTIVE The chemopreventive effects of Allium vegetables (onions, garlic, shallots, leeks, chives, and so forth) have been studied extensively, although their effect on gastric cancer risk is controversial. We performed a meta-analysis of cohort and case-control studies to analyze this

It has been shown that Allium species may help to prevent tumor promotion, cardiovascular diseases and aging; all processes that are associated with free radicals. Therefore the Allium species of both cultivated species (Allium nutans L., Allium fistulosum L., Allium vineale L., Allium psekemense B.
