Anthocyanin - Wikipedia
Anthocyanins (from Ancient Greek ἄνθος (ánthos) 'flower' and κυάνεος / κυανοῦς (kuáneos/kuanoûs) 'dark blue'), also called anthocyans, are water-soluble vacuolar pigments that, depending on their pH, may appear red, purple, blue, or black.

2023年12月28日 · The review summarizes current information about anthocyanins (AnC) and their localization in various plant organs and tissues. The pathways and regulation of AnC biosynthesis, the functional significance, and ecological role of these compounds in metabolism and adaptation of plants to environmental conditions are considered.
Anthocyanins impart color (from pink to blue) to various plant tissues and organs. The wide color spec-trum of AnC depends on the structural formula of the pigment (degree of hydroxylation, number or type of substituted groups), pigment concentration, pH of the medium, and the formation of complexes with metal cations.
