Centaurea iberica trevir. Ex spreng. Phytochemical content and evaluation of cytotoxicity, phytotoxicity, anti-inflammatory, larvicidal and anti-inflammatory potentials

Due to their tremendous therapeutic ability to treat a wide range of illnesses, medicinal plants are employed as a rich source and nutraceuticals practically in all civilizations. The goal of the current study was to evaluate phytochemistry and biological potentials of medicinal plant Centaurea iberica as previously no research work has been reported. To prepare plant extracts, five different solvents, methanol, ethanol, n-hexane, ethyl acetate and chloroform were used. Total phenolic content of the investigated plant was recorded highest in the methanolic extract ranges from 91 ± 1.2 mg/g, total flavonoid content recorded 24 ± 1.1 mg/g. Moreover, maximum LC₅₀ value (9.95 µg/mL) was recorded for methanolic extract using cytotoxicity assay. Radish seed germination phytotoxicity assay indicated the highest phytotoxic potential in n-hexane (55 % seed inhibition) extract of C. iberica. However, in anti-inflammatory assay less than 50 % inhibition was observed for methanolic extract and plant was found to be inactive against larvicidal activity. Based on the results of this study, it is recommended that more in vitro and in vivo research activities be done in the future, as well as chemical characterization to identify various compounds that may be utilized to treat various illnesses.
