Abstract
Abstract Mammalian cells have evolved a complex network of enzymatic and non-enzymatic molecules that protect them from the detrimental effects of reactive oxygen species (ROS). These endogenous antioxidant agents are supplemented by dietary antioxidants, obtained mainly from plants. Although many studies have assessed the antioxidant properties of fruits and vegetables, much less is known about the antioxidant characteristics of another commonly ingested plant product, tobacco. The antioxidant properties of 16 commercially available tobacco products were determined using an oxygen radical absorbance capacity (ORAC) assay. The concentrations of polyphenols in these products also were determined. The tobacco products tested had a range of antioxidant activity from modest to high. A significant linear relationship was observed between the overall antioxidant capacity and total phenolic content. The high antioxidant activity in smokeless tobacco may partially explain the low cancer risk associated with long-...
期刊介绍：
Chinese Tobacco Science is an academic scientific journal (bimonthly) under the supervision of the Ministry of Agriculture and Rural Affairs of the People's Republic of China, and sponsored by the Tobacco Research Institute of the Chinese Academy of Agricultural Sciences and the Qingzhou Tobacco Research Institute of China National Tobacco Corporation. It was founded in 1979 and is publicly distributed nationwide. The journal mainly publishes academic papers on scientific research results, new production technologies, and modern management in my country's tobacco science research and tobacco production technology. In addition, it also publishes forward-looking review articles in the field of tobacco research. There are columns such as tobacco genetics and breeding, cultivation technology, modulation and processing, physiology and biochemistry, plant protection, review or monograph, quality chemistry, etc.
