Eryngium species are commonly used for the treatment of
skin diseases and inflammation, as well as wound healing in folk medicine. It
has been revealed that Eryngium sp.
rich in compounds such as triterpene saponins, phenolic acids, flavonoids, and
steroids show antioxidant, antimicrobial and anti-inflammatory activity. The
aim of this study was to investigate the antioxidant, antityrosinase and
photoprotective potential of the ethanol extracts prepared from the aerial
parts of E. billardieri F.Delaroche using maceration and ultrasonic-assisted
microwave extraction methods. Antioxidant capacity was determined by ferric
reducing antioxidant power (FRAP), cupric ion reducing antioxidant capacity
(CUPRAC) and 1,1-Diphenyl-2-picrylhydrazyl radical (DPPH) assays and
photoprotective activity by in vitro
sun protection factor (SPF) determination. The phytochemical profile of the
more active extract was then determined using a validated LC-MS/MS method.
According to the activity results, the ethanol extract obtained by
ultrasonic-assisted microwave extraction was found to be more active in all
experiments. LC-MS/MS analysis of this extract confirmed the presence of 28
compounds including isoquercitrin, quercitrin, rosmarinic acid, hesperidin,
nicotiflorin, astragalin. Although further studies are needed, it is concluded
that the extract of E. billardieri
prepared using ultrasonic-assisted microwave extraction has significant
potential as a cosmetic product ingredient.
