Among the options for fruit species with market prospects, the blackberry (Rubus spp) stands out as one of the most promising. This is a species that has shown an increase of cultivated area in recent years in Rio Grande do Sul (main Brazilian producer). Regular consumption of fruits and vegetables is associated with low risk of incidence and mortality from cancer and heart disease due to the presence of compounds derived from secondary metabolism, especially flavonoids and anthocyanins, which have great capacity to react with free radicals that cause oxidative stress, and therefore contribute to the prevention of these diseases. The phenolic acids and flavonoids were identificated in the group of phenolic compounds in blackberry. Among the flavonoids, stands out the anthocyanins, which vary in concentration according to the stage of maturation of fruits. Based on the antocyanin content related in literature and the great variation between different genetic materials, there is great potential in the production of blackberry and its utilization as a natural colorant in the food and pharmaceuticals industry. In addition to these compounds, the blackberry also has other phytochemicals such as vitamin C, vitamin E and carotenoids. This paper aims to review literature of the main phytochemicals in blackberry (Rubus spp).
