Anthocyanin profile in Monastrell grapes in six different areas from Denomination of Origen Jumilla during ripening stage

P>The aim of our research has been to investigate the pattern of accumulation of anthocyanins in the skin of Monastrell variety and to establish if the fingerprint of this cultivar changed in six different areas from Denomination of Origen Jumilla during ripening stage in two consecutive seasons (2007 and 2008). The results show that the anthocyanin profile for Monastrell variety is maintained: it could be observed a higher proportion of non-acylated anthocyanins, a higher proportion of coumarylated than acetyl derivatives and a higher proportion of trihydroxylated than dihydroxylated anthocyanins. During ripening period, in all zones studied, we observed the same trends: increasing of cyanidin, peonidin and malvidin-3-glucoside and decreasing of the other two monoglucosides (delphinidin and petunidin). Slightly quantitative differences were observed for the different zones in the 2 years studied, leading to the conclusion that edaphoclimatic factors also influence the accumulation of anthocyanin compounds.
