Science
Mechanism of Action
This extract exerts its anti-inflammatory effects by inhibiting the production of various pro-inflammatory molecules, including nitric oxide (NO), inducible nitric oxide synthase (iNOS), prostaglandin E2 (PGE2), and cyclooxygenase-2 (COX-2). It also suppresses inflammatory cytokines such as TNF-α, IL-1ß, and IL-6, and deactivates MAPK signaling pathways (p38, ERK, JNK). Rich in phenolic and flavonoid compounds, the extract provides potent antioxidant activity through free radical scavenging, ferrous ion chelation, and enhancing reducing power, thereby protecting skin cells from oxidative damage.

Key findings
- 01 An ethyl acetate fraction of Hypochoeris radicata extract (HRF-EA) significantly inhibited the production of pro-inflammatory molecules (NO, iNOS, PGE2, COX-2) and cytokines (TNF-α, IL-1ß, IL-6) in LPS-stimulated RAW 264.7 cells in a concentration-dependent manner. Specifically, HRF-EA at 100 µg/mL, 200 µg/mL, and 400 µg/mL decreased NO production by 35%, 51%, and 82%, respectively.
- 02 Methanolic extracts of leaf and root at 250 µg/mL showed significant scavenging activity against DPPH free radicals (97.99% for leaf and 96.44% for root). At higher concentrations, such as 5000 µg/mL, it exhibited ferrous ions chelating activity (38.69% for leaf and 40.52% for root).

Stability
Specific optimal pH range for the extract's stability in cosmetic formulations is not specified. While the plant itself tolerates a broad soil pH range (3.9 to 8.6), this information does not directly apply to extract stability in a cosmetic matrix.
Safety
Safety Profile
No direct safety assessments by regulatory bodies such as CIR, SCCS, or FDA have been found for Hypochoeris Radicata Extract. However, in vitro studies have shown no toxic effects on cells at tested concentrations, suggesting a favorable cellular safety profile.
