Abstract Two acylated pelargonidin glycosides were isolated from red tubers of a anthocyanin-rich tetraploid potato which was successfully selected from hybrid seedlings between cultivars of Solanum tuberosum and S. andigena . The major pigment was identified as pelargonidin 3-O-[(4″-O-(trans-p- coumaroyl )-α- l -6″-rhamnopyranosyl -β- d -glucopyranoside ]-5-O-[β- d -glucopyranoside ] by chemical and spectral measurements, and another was determined to be pelargonidin 3-O-[(4″-O-(trans- feruloyl)-α- l -6″-rhamnopyranosyl-β- d -glucopyranoside ]-O-[β- d -glucopyranoside ] as a minor pigment.
