Herbal medicines have unique therapeutic properties and therefore, used in rural areas to cure different diseases. The crude phytochemicals (total phenols, flavonoids, tannins, carbohydrates and protein), vitamins (thiamine, niacin, riboflavin and ascorbic acid) and trace elements (calcium, phosphorus and iron) were determined quantitatively from the flowers of Hibiscus rosa sinensis and Hibiscus syriacus. The secondary plant products such as phenols, tannins and flavonoids were found maximum in Hibiscus syriacus whereas the primary metabolite namely carbohydrates and protein were higher in Hibiscus rosa sinensis. All the vitamins were higher in Hibiscus rosa sinensis than Hibiscus syriacus. The trace elements such as calcium and phosphorus were greater in Hibiscus syriacus whereas the content of iron was higher in Hibiscus rosa sinensis.
