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
