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...

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...

Catharanthus roseus (L.).G. Don, a highly valued medicinal plant suffers from a serious disease. A survey on the symptom and severity of the leaf blight of C. roseus was performed in the nurseries of the Institute of Forestry and Environmental Sciences (IFESCU), Bangladesh Council of Industrial Research (BCSIR) and Bangladesh Forest Research Institute (BFRI), Bangladesh. An observation was also...

This study was performed for comparison of meristem culture technique with shoot tip culture technique for obtaining virus-free plant, comparison of micropropagation success of two different nutrient media, and determination of effectiveness of real-time PCR assay for the detection of viruses. Two different garlic species (Allium sativum and Allium tuncelianum) and two different nutrient media ...

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...

The chromosome numbers and karyotypes of eight species the genus Allium distributed in Turkey were analyzed. These taxa are A. armerioides Boiss., orientale stamineum tuncelianum (Kollmann) Özhatay, B.Mathew & Şiraneci, subakaka Razyfard Zarre, muratozelii Armağan, dumanii Koyuncu Koçyiğit colchicifolium Boiss. Four them (A. armerioides, tuncelianum, dumanii) endemic Turkey. all studied determi...
