research Wound Healing Effect of Supercritical Carbon Dioxide Datura Metel L. Leaves Extracts: An In Vitro Study of Anti-Inflammation, Cell Migration, MMP-2 Inhibition, and the Modulation of the Sonic Hedgehog Pathway in Human Fibroblasts
This study investigates the wound healing properties of Datura metel L. leaf extracts obtained through supercritical carbon dioxide extraction. The extracts, Dm1 and Dm2, were analyzed for their phytochemical profiles and biological activities, including antioxidant and anti-inflammatory effects, cell migration, and modulation of the sonic hedgehog pathway in human fibroblasts. Both extracts demonstrated antioxidant properties comparable to l-ascorbic acid and significantly inhibited nitrite production. Dm1 showed notable wound closure rates of 58.46% and 82.62% after 36 and 48 hours, respectively, similar to commercial treatments. Additionally, both extracts suppressed MMP-2 expression, and Dm1 upregulated genes in the sonic hedgehog pathway, suggesting that the scCO2 extraction technique could enhance D. metel's potential for effective wound healing.
