Arctigenin 4'-O-β-gentiobioside is utilized in cosmetic formulations due to its skin-brightening and anti-aging properties, reducing melanin production for an even skin tone and providing antioxidant protection against oxidative stress and environmental damage. It is commonly found in natural skincare products addressing hyperpigmentation and dullness. In pharmaceutical and biological research, it demonstrates anti-inflammatory effects, antiviral activity (e.g., inhibiting influenza virus propagation), anti-cancer potential by suppressing cancer cell growth, and neuroprotective benefits, making it a promising lead compound for treatments of neurological disorders like Alzheimer's disease.
