Phytochemical and antimicrobial activity of aqueous extract of Hibiscus sabdariffa
Abstract
The calyces of Hibiscus sabdariffa are widely taken in the Northern and South-Western part of Nigeria for the treatment of diseases. Aqueous extract of Hibiscus sabdariffa was investigated for its phytochemical constituents and antibacterial activity. The extract was found to contain carbohydrates, tannins, saponins, flavonoids and exhibit antibacterial activity against Staphylococcus aureus and Escherichia coli and other organisms such as Klebsiella and Salmonella species at different concentrations (10-160mg/ml). The present result support the use of this plant in the treatment of diseases like abscesses, urinary tract infections, coughs and pneumonia in traditional medicine and also provide the basis for isolating antibacterial agents from Hibiscus sabdariffa.
