Rubus occidentalis is a black-fruited raspberry originating from North America. Its popularity and demand has been growing over the years, as studies outline its high anthocyanin and ellagitannin content and significance for human health. Interaction between chemical composition and pharmacological activity, mechanisms of action at cellular and molecular levels are all active areas of study. The vast majority of research concerning black raspberries is focused on chemoprevention and anticancer effects. This review summarizes the data on chemical composition and anticancer activity of black raspberry fruits throughout the years.

Department of Pharmacognosy with Medicinal Plant Garden, Faculty of Pharmacy, Medical University of Gdańsk, 80-416 Gdańsk, Poland.
The aim of this study was to compare the antioxidant potential in the fruits of different hybrids of and (four hybrids) against the fruit of known cultivars of both species (-three cultivars; -five cultivars) and, using chemometric analysis, to select factors affecting the level of polyphenols and antioxidant properties. Antioxidant activity was determined using the ABTS, DPPH and FRAP tests. Chemometric analysis enabled the separation of and cultivars and classified the hybrid / R1314701 as belonging to the species.

Over the last 10 years, global raspberry production has increased by 47.89%, based mainly on the red raspberry species (Rubus idaeus). However, the black raspberry (Rubus occidentalis), although less consumed, is resistant to one of the most important diseases for the crop, the late leaf rust caused by Acculeastrum americanum fungus.
