Phytochemical profile and multi-target biological activities of Sideritis lanata water extract: antioxidant, enzyme inhibition, and anti-inflammatory potential. (PubMed, Prep Biochem Biotechnol)
Phenolic profiling by liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) revealed a phenolic-acid-dominated signature, mainly hydroxycinnamic acids led by chlorogenic acid (691 µg/g), followed by caffeic acid (231 µg/g), p-coumaric acid (211 µg/g), and ferulic acid (50.4 µg/g), together with abundant hydroxybenzoic acids such as 3- and 4-hydroxybenzoic acids (188 and 183 µg/g, respectively)...In A549 lung carcinoma cells, viability decreased concentration-dependently; at the half-maximal inhibitory concentration (IC50), tumor necrosis factor-alpha (TNF-α) increased to 26.73 ng/mL, whereas transforming growth factor-beta (TGF-β) and interleukin-1 beta (IL-1β) decreased to 9.4 and 10.83 pg/mL, respectively, while at ½ × IC50 TNF-α was 1.3 ng/mL and TGF-β reached 46.6 pg/mL. Overall, this hydroxycinnamate- and hydroxybenzoate-rich aqueous extract exhibits moderate, target-selective antioxidant and enzyme-inhibitory activities together with dose-dependent immunomodulatory effects.
