Crepis foetida L. subsp. rhoeadifolia (Bieb.) Celak. as a source of multifunctional agents: Cytotoxic and phytochemical evaluation

The cytotoxic, anticholinesterase, antityrosinase and antioxidant effects of methanol extract from the flower of C. foetida subsp. rhoeadifolia (CFRME) were evaluated. The cytotoxic effect was investigated using HepG2, Caco-2, MCF-7 and MCF-10A cell lines. Enzyme inhibitory activities were tested by spectrophotometric methods. Different chemical assays were used to determine the antioxidant effects. In addition, phenolic constituents were quantified. High-performance liquid chromatographic (HPLC) analysis revealed that chlorogenic acid was the major phenolic component in the extract. The extract showed a strong antiproliferative, antioxidant, and anticholinesterase and antityrosinase effects. These findings suggest that C. foetida subsp. rhoeadifolia may be considered as a source of ingredients that can be used as food supplements.
