Two novel anthocyanins, delphinidin 3-O-(6-O-(2-O-acetyl-α-rhamnopyranosyl)-β-glucopyranoside) and delphinidin 3-O-(6-O-(3-O-acetyl-α-rhamnopyranosyl)-β-glucopyranoside), were identified from the anthers of Tulipa gesneriana. These and delphinidin 3-O-(6-O-(α-rhamnopyranosyl)-β-glucopyranoside) made up over 80% of the anthocyanin content in the dark purple anthers and could be responsible for the intense color of the anthers. 
Red-purple flower color and delphinidin-type pigments in the flowers of Pueraria lobata (Leguminosae).
TLDR
It may be assumed that the unusually low pH in the vacuole of fresh petals plays an important role to form red-purple flower color against weak acidic pH inThe vacuoles of old violet P. lobata petals. Expand
Anthocyanin content of Tulipa species and cultivars and its impact on tepal colours
TLDR
Flowers of tulips (17 species and 25 cultivars) were subjected to qualitative and relative quantitative examination for anthocyanins, finding that orange coloured tepals were to a large extent correlated with high relative proportions of the pelargonidin derivatives, 3 and 5 . Expand
Anthocyanins of grasses
TLDR
Anthocyanins acylated with one and/or two malonic acid moieties dominated the anthocyanin profiles of all the species in the subfamilies Pooideae and Panicoideae. Expand
Anthocyanins in the Bracts of Curcuma Species and Relationship of the Species Based on Anthocyanin Composition
TLDR
Cluster analysis based on four major anthocyanins formed two clusters that consisted of only one species, C. alismatifolia, and the other consisted of five, which further formed sub-clusters depending on either species or habitats. Expand
Perianth bottom-specific blue color development in Tulip cv. Murasakizuisho requires ferric ions.
TLDR
It is established that Fe(3+) is essential for blue color development in the tulip. Expand
Comparison of anthocyanin components, expression of anthocyanin biosynthetic structural genes, and TfF3′H1 sequences between Tulipa fosteriana ‘Albert heijn’ and its reddish sport
TLDR
Investigating the molecular basis underlying this color difference in a reddish flower tulip sport Tulipa fosteriana ‘SN09’ found that the insert mutation in the Tf3′H1 promoter hampered the accumulation of cyanidin anthocyanins in SN09 through the reduction of TfF3′ H1 transcription. Expand
Anthocyanins of the anthers as chemotaxonomic markers in the genus Populus L.. Differentiation between Populus nigra, Populus alba and Populus tremula.
TLDR
These analyses have revealed intraspecific differences among samples that point out to different clones or varieties of a same species, and anthocyanins of the anthers of this species are valuable chemotaxonomic markers for this species. Expand
Anthocyanin Components and Mechanism for Color Development in Blue Veronica Flowers
TLDR
3-Di-p-coumaroylsophoroside-5-malonylglucoside and its demalonyl derivative were isolated from blue petals of Veronica persica Poiret and only the demaloneylated pigment was detected in the blue anthers. Expand
Coloration and Anthocyanin Profile in Tulip Flowers
TLDR
Anthocyanins seem to be tissue-specifically bio-synthesized, resulting in formation of a color pattern between inner and outer parts of the tulip flower. Expand
Regulation of gene expression involved in flavonol and anthocyanin biosynthesis during petal development in lisianthus (Eustoma grandiflorum)
To elucidate gene regulation of flower colour formation, the gene expressions of the enzymes involved in flavonoid biosynthesis were investigated in correlation with their product during floralExpand
