Pterosin D 3-O-glucoside is a secondary metabolite isolated from ferns, particularly species in the Pteridium genus. It exhibits antioxidant properties, making it suitable for skincare formulations to protect skin cells from oxidative stress and environmental damage. It shows potential in anti-aging products by supporting cellular repair mechanisms. Additionally, it is investigated for anti-inflammatory effects in topical applications to soothe irritated or sensitive skin. In plant biology, it plays a role in defense responses against environmental stressors, with possible applications in agricultural biotechnology as a natural protective agent.
