A HPLC method that allows the separation of several anthocyanins present in red grapes
and red wines, using a linear gradient of acetonitrile in water at pH 1.3, using perchloric acid …

The genetics and biochemistry of anthocyanins and flavonol biosynthesis and their role in
plant organ pigmentation is well established in model species. However, the genetic basis of …

The wild grapevine, Vitis vinifera L. ssp. sylvestris (Gmelin) Hegi, considered as the ancestor
