Science
Mechanism of Action
This extract’s anti-inflammatory action stems from salicylate derivatives and its ability to suppress phosphorylation of mitogen-activated protein kinases (MAPKs) and p65-nuclear factor-kappa B (NF-κB), thereby reducing inflammation triggered by irritants. As a robust antioxidant, it actively scavenges free radicals, suppresses reactive oxygen species (ROS) production, attenuates lipid peroxidation, and enhances the Nrf2 pathway, leading to increased endogenous antioxidant enzyme activity and restored glutathione concentrations. The presence of tannins contributes astringent properties, promoting skin cleansing, tightening pores, and fostering a firmer, rejuvenated skin appearance.

Key findings
- 01 In vitro studies demonstrate that Spiraea prunifolia var. simpliciflora extract effectively scavenges DPPH radicals and suppresses reactive oxygen species production in NCI-H292 cells, showcasing its significant antioxidant capacity.
- 02 A murine model of acute lung injury showed that oral administration of Spiraea prunifolia var. simpliciflora (50 or 100 mg/kg) significantly reduced inflammatory markers such as TNF-α, IL-1β, and IL-6. This was accompanied by suppressed MAPK and NF-κB phosphorylation and enhanced Nrf2 activation, confirming its robust anti-inflammatory and anti-oxidative potential.
