Anti-aging Effects of Rosa damascena Extract Containing Low Molecular Glycoprotein

In this study, we investigated the anti-aging effect of Rosa damascena extract containing low molecular glycoprotein (RELG) converted from the high molecular glycoprotein by bioconversion. Free radical scavenging activities were performed by 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. Antioxidant activities (IC50) of RELG and the positive control ascorbic acid were 22.6 μg/mL and 21.1 μg/mL, respectively. For skin cells, 15 μg/mL RELG showed 28% antioxidant activity by inhibiting the production of active oxygen species induced by ultraviolet ray and hydrogen peroxide. 15 μg/mL RELG prevented 10% the cell death caused by stress in human hair follicle dermal papilla cells (HDPC) and reduced 90% the production of active oxygen species. In addition, the glycoprotein showed not only anti-wrinkle effect but also moisturizing effect by 48% inhibition of matrix metallo proteinase-1 (MMP-1) production by ultraviolet stress and 10 μg/mL RELG enhanced 10% neutral lipid synthesis with 44% aquaporin 3 (AQP3) expression, which is moisture factor. In conclusion, the RELG can be used as an anti-aging cosmetic material.
