Phyochemical Analysis of Aqueous Flower Extract of Hibiscus sadariffa (Zobo Flower)

The phytochemical analyses of Hibiscus sabdariffa was extensively carried out using Harborne method. The qualitative test of the phytochemical analyses revealed the presence of some secondary metabolites such as flavonoids, glycosides, tannins, acidic compounds and steroids. Macronutrients such as proteins, carbohydrates and reducing sugars were also found to be present. The results of the analyses also revealed the differences in solubility of the phytochemicals and macronutrients in polar solvent (water). In this study, flavonoids, tannins and carbohydrates were found to be present in higher concentration. On the other hand, bioactive compounds such as glycosides, steroids, acidic compounds, proteins and reducing sugars were found to be present in moderate concentration while alkaloids, saponins, terpenoids and fats and oil were absent in the zobo flower.
