Therefore, determination of anthocyanin content of Ethiopian Roselle genotypes was an aim for this study. Besides, the superior anthocyanin that yielded Roselle genotype was selected and determined its nutritional profile and standardized the herbal tea preparation protocol from the calyx. The standardization was governed by determining the principal active constituent (anthocyanin) based on the pH differential method through UV-Visible spectrophotometer.
