Biochemical data

Hibiscus sabdariffa contains mainly heterogenous polysaccharides and many phenolic compounds.23,24

Anthocyanins - Anthocyanosids (about 1.5%)
Hibiscus sabdariffa contains basically monomeric and some copigmented and polymeric anthocyanins. These molecules are responsible for the red colour given to the herbal tea.1,23,27,28

Organic acids (15 to 30%) . protocatechuic acid, hibiscus acid, chlorogenic acid
The calyces of Hibiscus sabdariffa are characterized by a high level in organic acids. These organic acids are specific of the drug and are responsible for the pleasant acidic flavour or the soft drink made from Hibiscus.23,29

PACs

Flavonoïds, flavonols (Quercetin, Myricetin), flavons (Luteolin, luteolin glycoside) 23,27

Polysaccharides : forming mucilage (mainly galactose, galacturonic acid, rhamnose.8 – Other forms like rhamnogalacturonane, arabinogalactan and arabinan have also been detected) and pectin 27,30

The presence of many other components has also been reported : vitamins (B-carotene, riboflavin, thiamin, niacin) and minerals : the pharmacological properties of these compounds have not been completely explored – nevertheless, the medicinal effects that could be produced by Hibiscus sabdariffa have been attributed to the flavonoïds.10
