The cancer preventive activity of vitamin E has been extensively discussed, but the activities of specific forms of tocopherols have not received sufficient attention. Herein, we compared the activities of d-tocopherol (d-T), g-T, and a-T in a colon carcinogenesis model. Male F344 rats, seven weeks old, were given two weekly subcutaneous injections of azoxymethane (AOM) each at a dose of 15 mg/...
Although dietary intake of tomatoes and tomato products containing lycopene has been reported to reduce the risk of prostate cancer, few studies have been done on the relationship between plasma lycopene and other carotenoids and prostate cancer. This case-control study was conducted to investigate the effects of plasma lycopene, other carotenoids, and retinol, as well as alpha- and gamma-tocop...

abstract: the object of this study is to extract the oil from millets and evaluate the chemical properties of the extracted oil. commercial millet oil was obtained by cold solvent extraction adopting soxhlet procedure. quantitative and qualitative tests concerned with the non-saponifiable matter, fatty acid composition, phosphorus content representing total phospholipids, refractive index, pero...
A molecular gel system was assembled on carrier particles and the integrated effect of weak interaction sites enabled highly efficient separation of the bioactive and shape-constrained isomers of tocopherols, β-carotene, and polycyclic aromatic hydrocarbons (PAHs) by multiple interaction mechanisms.
Abstract Safflower is a minor oilseed crop in Australia where the market is dominated by canola, cottonseed and sunflower. Safflower however offers an alternative oilseed crop in marginal areas. This study was designed to evaluate current safflower lines and to determine their potential value both for edible oil and meal for animal feed. Two sets of samples were analysed. The first was a collec...
