A combined technique has been developed for the preparative isolation of anthocyanins from blackcurrant (Ribes nigrum) fruits. Frozen berries (370 g) were extracted three times with 11 of methanol containing 0.1 per cent TFA at 4°C for 6 h. The combined exracts were concentrated, diluted to 250 ml with water and extracted with ethyl acetate. The aqueous phase was concentrated to 100 ml and applied in an ion-exchange column. The column... 

Novel pyranoanthocyanins have also been isolated and identified in blackcurrant (Ribes nigrum) seed using HPLC, 2D NMR and ES-MS. Blackcurrant seeds were extracted with acetone-water (70 30, v/v) and the components of the extract were separated in a polyamide column followed by HPLC-DAD. The new pigments were finally separated in an MCI-HP20 column. The chemical structures of anthocyanins 1-2 and the novel pyranoanthocyanins 3-6 with the pyrano[4,3,2-de]-l-bcn/opyrylium core structure are shown in Fig. 2.110. It was stated that the analytical method developed separated well the novel pyranoanthocyanins [245],...

Anthocyanins occur in abundance in berries where they provide the fruits with their distinctive and vibrant palate of colors. Cranberry (Vaccinium macrocarpori), blackberry, and elderberry (Sambucus nigra) contain derivatives of only one type of anthocyanin (i.e., cyanidin), while a wide array of anthocyanins is found in blueberry (Vaccinium corymbosum) and blackcurrant (Ribes nigrum) (Fig. 1.21).
