Comparison of some bioactive compounds of four medicinal plants

In this study, determination of the antioxidant activity, total phenolic content (TPC) and Total flavonoid content (TFC) as well as some bioactive compounds in four medicinal plants is aimed. The plants: Urtica dioica, Peganum harmala, Citrullus colocynthis and Syzygium aromaticum clove were subject to test. The extraction technique used in this study included maceration extraction by employing methanol as a solvent. The obtained values are between 0.2-574 mg/g for TPC, 0.4-8.4 mg/g for TFC, 11.3-484 mg/g for FRAP, and 123-1979 mg/g MCC. Further, HPLC was utilized to evaluate the extrcats obtained. THe bioactive compoubds were determined by using HPLC – DAD device.
