The pigment is called daphniphylline. It is formerly known as Hibiscin. This is the major pigment.
What is the pigment of the hibiscus flower called?
Hibiscus or Rosemallow is a large genus of about 200-220 species of flowering plants in the family Malvaceae, native to warm temperate, subtropical and tropical regions throughout the world. The genus includes both annual and perennial herbaceous plants, and woody shrubs and small trees. The leaves are alternate, simple, ovate to lanceolate, often with a toothed or lobed margin. The flowers are large, conspicuous, trumpet-shaped, with five petals, ranging from white to pink, red, purple or yellow, and from 4-15 cm broad.



so....which exactly pigment do u mean?



eight aglycones(Flavonoids) were found in the Hibiscus flower extracts, including delphinidin, cyanidin, petunidin, myricetin, pelargonidin, malvidin, quercetin, and kaempferol.



In the petals, the combined effects of the pigments can best be imagined by visualizing a paint mixture on an artist's palette: e.g., red and white give pink; red and yellow, orange.



Flavonoids include red or blue anthocyanins and white or pale yellow compounds such as rutin, quercitin, and kaempferol . Flavonoids in flowers and fruit provide visual cues for animal pollinators and seed dispersers to locate their target. They also occur in most other plant parts and in most genera. Flavonoids are located in the cytoplasm and plastids. Like carotenoids and flavonoids in flowers and fruit, betalains also are likely to play an important role in attracting animals . These red-violet (betacyanin) and yellow (betaxanthin) pigments, which are located in the cytoplasm of plant tissue, only occur in about 10 plant families (and always independent of anthocyanins).



Anthocyanin pigments in flowers are generally pink, red, or purple. Cyanidin is a red or pink pigment; pelargonidini is the brick-red pigment of geraniums. Both Cyanidin and Pelargonidin are found in Hemrocallis. The blue anthocyanin pigment, Delphinidin, is also found in Hemerocallis, but apparently in quantities too small to produce a blue appearance. Or perhaps the internal pH of the cell vacuole is not high enough to produce the blue color.



A red flower is red because it contains a red pigment called anthocyanin (the same pigment that dyes autumn leaves red). Similar pigments occur in pink, red, and, surprisingly, blue petals. The degree of acidity of cell sap influences the color. If the sap is acid, petals look red. If it is neutral, they look blue.



The principal blue/purple pigment is called cyanidin
