Per 100 g serving providing 63 kilocalories, the raw fruit has high vitamin C content (218% of the Daily Value, DV) and moderate levels of iron and manganese (12% DV each). Other nutrients are present in negligible amounts (less than 10% DV, table). Polyphenol phytochemicals present in the fruit, seeds and leaves, are being investigated for their potential biological activities. Major anthocyanins in blackcurrant pomace are delphinidin-3-"O"-glucoside, delphinidin-3-"O"-rutinoside, cyanidin-3-"O"-glucoside, and cyanidin-3-"O"-rutinoside, which are retained in
