Currants are glossy red or black berries that grow on thornless upright shrubs. To be classified as a currant, the bush must be in the genus Ribes. Native to the Northern Hemisphere, these plants have been cultivated throughout Europe and Asia for centuries.
Black currant (Ribes nigrum L., Grossulariaceae) is known to contain high amounts of anthocyanins (250 mg/100 g fresh fruit). Black currant fruits have been used in Asian and European traditional medicine for the treatment of a variety of diseases.he aqueous extract yielded an anthocyanin-rich fraction with cyanidin-3-O-rutinoside as one of the major anthocyanins. This fraction exhibited a potent cytotoxic effect on HepG2 cells and this effect was more pronounced than that of delphinidin and cyanidin, two major aglycones of anthocyanins present in black currant.
