Via HPLC-MS, 19 anthocyanins were identified as monoglucosides and their derivatives. Anthocyanin composition and concentration varied among grape organs and by developmental stage. Skin anthocyanins were mainly composed of malvidin-derivatives, while peonidin-derivatives were the most dominant anthocyanins in the pulp. In carpopodia (swollen pedicel at point of berry attachment), berry pedicels, leaf lamina, vein and petioles, and living bark at the base of the shoot, both malvidin- and peonidin-derivatives were predominant components. Anthocyanins were very low before veraison, and then sharply increased at veraison in berry skin and pulp. Anthocyanins in carpopodia and berry pedicels also showed sharp increases, though occurring later than in berry skin and pulp. Anthocyanins were high in young and senescing leaf lamina, and low in expanding and mature lamina. Anthocyanins did not vary much in leaf vein and petiole tissue, or in bark, throughout the growing season.}, issn = {0002-9254}, URL = {https://www.ajevonline.org/content/early/2012/02/06/ajev.2011.11063}, eprint = {https://www.ajevonline.org/content/early/2012/02/06/ajev.2011.11063.full.pdf}, journal = {American Journal of Enology and Viticulture} }
