Data: 2010 - Rosa micrantha as a powerfull source of antioxidants. In International Symposium on the Patophysiology of Reactive Oxygen and Nitrogen Species. Salamancahttp://hdl.handle.net/10198/3697Reactive oxygen (ROS) and nitrogen (RNS) species production inevitably occurs during normal cell metabolism both in animals and plants. An excess of those species lead to oxidative and nitrosative stresses, resulting in damage for some cellular molecules such as DNA, proteins and lipids. Natural antioxidants have become a safety option to avoid biological oxidations involved in cellular damage and deterioration of food quality. Rosa micrantha is one of the rose species that grow feral in the Northeastern Portuguese region so called Nordeste Transmontano.engconference object
