Anthocyanins

Changes in anthocyanin, flavonoid and phenolic acid concentrations during development and storage of coloured potato (Solanum tuberosum L) tubers

“…A number of workers have reported that plants tend to produce more anthocyanins when cellular sugar levels are high (reviewed in Hrazdina). 19 After cold storage, the tubers had higher concentrations of anthocyanin in the bud end and, because the concentration of anthocyanin increased during cold storage, it was proposed that an increase in sugars (substrates for biosynthesis) promoted anthocyanin biosynthesis. It could be that because the sugars were mobilised towards the bud end (and the sprouts), anthocyanin biosynthesis was higher there than at the stem end, where the concentration of sugars was lower.…”

Analysis of Petal Anthocyanins to Investigate Flower Coloration of Zhongyuan (Chinese) and Daikon Island (Japanese) Tree Peony Cultivars

“…2) The anthocyanins found in tree peony flowers were based on a 3,4-and/or 4-hydroxylated structure, with 3-0-methylated anthocyanin which is the dominant character as a flower pigment. Flower anthocyanins have been used as genetic markers (Hrazdina 1982). We believe that the anthocyanins in tree peony flowers would provide a chemical classification of both origin and the cultivar level enabling us to understand not only the relationship between anthocyanin composition and flower coloration but also phylogeny of tree peony.…”

Phenetics in Tree Peony Species from China by Flower Pigment Cluster Analysis

“…Much research on anthocyanins as genetic markers was done in the 1960s and 1970s and the same methodology is Pseudo R-Squared still being used for plant chemical taxonomy today (Hrazdina 1982, Bohm 1998, lwashina 2000. Anthocyanidins, which have 3,4'-and/or 4'-hydroxylated structures (Table 2), were found in all 15 accessions of wild tree peony in this study.…”
