Malvidin-3-acetylglucoside

Fig. 2.101. Chromatograms of Cabernet Sauvignon and TempraniUo wines recorded at 520 nm. Peak identification Df-3-GL = delphinidin-3-O-glucoside Cy-3-Gl = cyanidin-3-O-glucoside Pt-3-Gl = petunidin-3-O-glucoside Pn-3-Gl = peonidin-3-O-glucoside Mv-3-Gl = maMdin-3-O-glucoside Pn-3-Gl-Ac = paeonidin-3-O-acetylglucoside Mv-3-Gl-Ac = maMdin-3-O-acetylglucoside Pn-3-Gl-Cm = peonidin-3-coumaroylglucoside Mv-3-Gl-Cm = malvidin-3-coumarylglucoside.

Two series of ions are evident, representing monoglucosides (1-5) and acetylglucosides (6-10) of the following aglycones cyanidin (1, 6 1.40), peonidin (2, 7 1.41), delphinidin (3, 8 1.42), petunidin (4, 9 1.43) and malvidin (5, 10 1.44). These results were obtained with a first-generation (continuous mode) MALDI mass spectrometer that did not have delayed... 

Complex anthocyanin patterns are observed in red grapes. The 3-glucosides, 3-acetylglucosides and 3-/J-coumaroylglucosides of cyanidin, peonidin, delphinidin, petunidin and malvidin are present.
