Science
Mechanism of Action
This extract leverages a diverse array of bioactive compounds, including vitamins, flavonoids, and phenolic compounds, to exert its effects. It effectively alleviates oxidative stress by activating the Nrf2 pathway, which in turn enhances the expression of vital antioxidant enzymes such as superoxide dismutase and catalase. Simultaneously, it modulates inflammatory responses by inhibiting key signaling pathways, including JAK1/STAT1 and NF-κB, thereby suppressing inflammatory cytokines (e.g., IL-33, IL-6, and IL-8). Furthermore, its amino acid content supports skin health and regeneration, contributing to improved texture and a more youthful appearance. The extract also functions as a skin protectant, reinforcing the natural skin barrier by increasing the expression of essential barrier proteins like filaggrin and claudin-1.

Key findings
- 01 Petroselinum crispum leaf and stem extracts, at a concentration of 400 µg mL⁻¹, demonstrated 50.9% protection against H₂O₂-induced DNA damage in mouse fibroblasts.
- 02 At 300 µg mL⁻¹, Petroselinum crispum leaf and stem extracts inhibited H₂O₂-induced MCF-7 cell migration by 41% ± 4%.
- 03 Hydro-ethanolic extracts of parsley (HEP) exhibited in vitro antioxidant and anti-inflammatory properties on human keratinocytes (HaCaT cells) at concentrations of 1, 5, and 10 µg/mL, showing no cytotoxicity at 25 µg/mL or lower.
- 04 An aqueous extract of Petroselinum crispum displayed high antioxidant activity, with an EC50 of 15.50 mg mL⁻¹ as measured by the DPPH method.
