the sepals is an anthocyanin, delphinidin- o -glucoside ( Takeda et al., 1985 ), whose flavylium cation provides the characteristic pink-red color to hydrangea sepals ( Moncada et al., 2003 ). Sepals turn blue because this anthocyanin forms a complex

Eggplant fruit color is influenced by the presence or absence of anthocyanins and chlorophylls and the concentration as well as distribution of these compounds. Anthocyanins are located in fruit epidermal cells and chlorophylls are found in

of anthocyanins, the prominent pigments in higher plants. The biochemistry and genetics of the anthocyanin-generating flavonoid biosynthetic pathway have been extensively studied ( Davies, 2000 ; Griesbach, 2005 ; Irani et al., 2003 ; Koes et al

Pigmentation of plant vegetative tissue, including leaves, stems, and roots and reproductive tissue in flowers and fruit, is attributed to anthocyanin and carotenoid pigments. These colored compounds are produced by independent metabolic pathways

Flavonoids are generated via a branched biosynthetic pathway that yields both colorless compounds (e.g., flavonols) and colored pigments, such as anthocyanins, polymeric phlobaphenes, and proanthocyanidins ( Koes et al., 2005 ). Flavonoids

Anthocyanins are plant pigments responsible for the coloration in many fruits, vegetables, and flowers, whereas others are colorized by carotenoids and betalains. These red/violet pigments impart an aesthetic appeal to the cultivars in which they

. (1979) demonstrated that anthocyanins were the main pigments responsible for the various spathe colors of anthurium and identified two anthocyanins [cyanidin 3-rutinoside (red) and pelargonidin 3-rutinoside (orange)] in red-, orange-, pink-, and coral
