Centaurea pichleri subsp.
pichleri,
Conyza canadensis, and
Jasminum fruticans are traditionally used plants grown in Turkey. Methanol extracts were obtained from these plants and pharmacological activity studies and phytochemical analyses were carried out. To evaluate the phytochemical composition, spectrophotometric and chromatographic techniques were used. The extracts were evaluated for antioxidant activity by DPPH
●, ABTS
●+ radical scavenging, and FRAP assays. The cytotoxic effects of the extracts were investigated on DU145 prostate cancer and A549 lung cancer cell lines. The anti-inflammatory effects of extracts were investigated on the NO amount, TNF-α, IFN-γ, and PGE 2 levels in lipopolysaccharide-stimulated Raw 264.7 cells. The richest extract in terms of phenolic compounds (98.19 ± 1.64 mg
GAE/g
extract) and total flavonoids (21.85 ± 0.64 mg
CA/g
extract) was identified as
C. pichleri subsp.
pichleri methanol extract. According to antioxidant activity determinations, the
C. pichleri subsp.
pichleri extract was found to be the most active extract. Finally, the
C. pichleri subsp.
pichleri methanol extract was revealed to be the most effective inhibitor of viability in the cytotoxic activity investigation, and the extract with the best anti-inflammatory action. The findings point to
C. pichleri subsp.
pichleri as a promising source of bioactive compounds in the transition from natural sources to industrial uses, such as new medications, cosmeceuticals, and nutraceuticals.
