Roselle is associated with traditional medicine and is reported to be used as treatment for several diseases

such as hypertension and urinary tract infections. The plants are rich in anthocyanins, as well as protocatechuic

acid. The dried calyces contain the flavonoids gossypetin, hibiscetine and sabdaretine. The major pigment,

formerly reported as hibiscin, has been identified as daphniphylline. Small amounts of myrtillin, Chrysanthenin ,

and delphinidin are also present. Roselle seeds are a good source of lipid-soluble antioxidants, particularly

gamma-tocopherol .
