This study was designed to investigate in vitro biological activities and phytochemical composition of aqueous and ethanolic extracts from Achillea sintenisii Hub-Mor. (AS). To deter-mine the chemical composition of AS extracts, phytochemical analyses were performed by using HPLC-ESI-Q-TOF-MS-MS. Afterwards, both extracts were investigated in terms of their effect on fibroblast proliferation, collagen synthesis, and hydrogen peroxide-induced damage. In addition to cell culture analysis, antibacterial, antioxidant, hyaluronidase inhibitory activities and total phe-nolic contents of the extracts were analyzed in cell-free systems. Our results demonstrated that the aqueous and ethanolic extracts did not show cytotoxic activity on fibroblasts, on the contrary, pro-moted fibroblast proliferation. Both AS extracts potently inhibited hyaluronidase activity and the inhibitory effect of ethanolic extract was comparable with the positive control, especially at high concentrations. The aqueous extract was the potent stimulator of collagen synthesis at 200 mg/mL concentration. Although the ethanolic extract showed antibacterial activity against all gram -positive bacteria, the aqueous extract was only effective against K. pneumoniae and B. subtilis. The ability of AS extracts, which have a rich phenolic compound content (>= 50 mg GAE/g), to scav-enge free radicals and protect fibroblasts against hydrogen peroxide-induced damage can be consid-ered as a result of their antioxidant potential. Our findings scientifically support the widespread use of this plant, by demonstrating the pharmacological properties of the extracts.(c) 2022 The Author(s).
