2004

Phytochemicals and phytomedicines are now an expanding research fields. A great number of active agents occurring in plants and herbs have been discovered, which is fundamental to find a rationale for the health effects of these herbs, in many cases used for centuries as traditional remedies. The knowledge of the mechanisms and molecular basis of their action is the final objective to understand the mode of action of the discovered principles. Studies on the bioactivity of cactus pear are very recent and results obtained so far, while exciting, now generate new questions. In vivo studies on healthy humans showed a strong protection of the body antioxidant system, and a marked reduction of p…

Antioxidant activity of cactus pear fruits and bioavailability of betalan components in healthy humans

2008

Consumption of fruit and vegetables is now associated with protection against various pathologies, including cancer and cardiovascular and cerebrovascular diseases, in which oxidative damage is an important etiologic factor. Various compounds from plant food, acting independently of known nutrients and micronutrients, have appeared very important in protecting human health. Most of these components can act as antioxidants or affect redox-dependent cell activities involved both in physiological and pathological events. In this scenery fruits of cactus pear (Opuntia ficus-indica), and the characteristic betalain pigments have recently attracted the attention of researchers. While suggesting m…
