spiraeoside

Spiraeoside is a naturally occurring flavonoid glycoside, specifically the 4'-O-glucoside of quercetin. It is a primary bioactive component of meadowsweet (*Filipendula ulmaria*) and is also found in other botanical sources such as onions. Spiraeoside exhibits antioxidant, anti-inflammatory, and geroprotective properties. Research has focused on its ability to modulate neuroinflammation and proteostasis, suggesting potential therapeutic applications in aging-related neurodegenerative disorders like Parkinson's disease. It is typically encountered as a constituent of herbal extracts or dietary supplements rather than as a purified pharmaceutical agent.
