Epidemiologic and laboratory studies suggest that allium vegetables and garlic constituents have antitumor effects. In a population-based, case-control study conducted in Shanghai, China, we investigated the association between intake of allium vegetables, including garlic, scallions, onions, chives, and leeks, and the risk of prostate cancer. We administered in-person interviews and collected ...

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 identification of flavonoids and anthocyanins, and their individual quantities, was determined by high-performance liquid chromatography (HPLC). The potency of both ex...

Purple blotch, caused by Alternaria porri (Ellis) Cifferi, is a serious disease incurring heavy yield losses in the bulb and seed crop of onion and garlic worldwide. There is an immediate need for identification of effective resistance sources for use in host resistance breeding. A total of 43 Allium genotypes were screened for purple blotch resistance under field conditions. Allium cepa access...

Allium sp. vegetables are widely consumed for their characteristic flavour. Additionally, their consumption may provide protection against cardiovascular disease due to their antiplatelet and antioxidant activities. Although antiplatelet and antioxidant activities in Allium sp. are generally recognised, comparative studies of antiplatelet and antioxidant potency among the main Allium vegetable ...

The aim of this study was to evaluate plant extracts for antifungal activities against Phythopthora infestans (Mont.) de Bary, an important pathogen of potato which causes late blight disease. Acetone, ethyl acetate and water extracts of garlic (Allium sativum L.), Pawpaw (Carica papaya), Neem (Azadirachta indica), Mexican marigold (Tagetes minuta) and peri –winkle (Vinca rosea) were screened i...

In the present study we aimed to evaluate the effects of methanolic extracts of the bulbs of Garlic (Allium sativum L., Alliaceae) and Persian shallot (Allium ascalonicum L., Alliaceae ) and leaves of Sage (Salvia officinalis L., Lamiaceae ), ASE, AAE and SOE respectively, on the antioxidant enzymes such as superoxide dismutase (SOD), glutathione peroxidase (GPX) and catalase (CAT) activities a...

BACKGROUND The chemical assignment of metabolites is crucial to understanding the relation between food composition and biological activity. OBJECTIVE This study was designed to detect and chemically assign sulfur-containing metabolites by using LC-Fourier transform ion cyclotron resonance-mass spectrometry (FTICR-MS) in Allium plants. METHODS Ultrahigh resolution (>250,000 full width at ha...

epidemiologic studies show that the cardiovascular diseases are associated with multiple factors such as raised serum total cholesterol, increased ldl, increased platelet aggregation, hypertension and smoking. in-vitro studies have confirmed the ability of some plants of allium species to reduce these parameters. therefore, we evaluated anti-platelet aggregation effect of some allium species (a...
