Introduction. Raspberry is an economically important berry crop;
its fruit contains numerous phenolic compounds with potential health benefits. It is known
that the chemical content of the fruit is affected by processing factors, but limited
information is available on the influence of production factors or impact of genotypes.
Materials and methods. The raspberry cultivars tested in our study were
Autumn Bliss, Batum, Heritage, Polana (red fruits) and Golden Bliss (yellow fruits); a
hybrid boysenberry and a black raspberry (black fruits). The plants were grown in two
subtropical areas in Brazil. Harvested fruits were used to determine the contents of
bioactive compounds (anthocyanins, ascorbic acid, β-carotene, lycopene and total phenols),
antioxidant activity and mineral composition (nitrogen, phosphorus, potassium, calcium,
magnesium, sulfur, boron, copper, manganese, zinc and iron). Results. Our
results revealed a strong influence of the site on the parameters evaluated and indicated
the existence of variation among the cultivars. In general, colored raspberries are a rich
source of nutrients, especially nitrogen, potassium, iron and manganese, and contain
significant amounts of bioactive compounds.
