(±)-Gnetuparin A: a pair of stilbene enantiomers from Gnetum parvifolium and their xanthine oxidase inhibitory activity

Key Points

• To investigate the inhibitory activity of stilbene enantiomers derived from Gnetum parvifolium on xanthine oxidase.
• Isolation of (±)-gnetuparin A from Gnetum parvifolium stems
• Characterization of enantiomers using spectroscopic methods
• Assessment of xanthine oxidase inhibitory activity
• Both enantiomers demonstrate significant inhibition of xanthine oxidase
• Inhibition rates suggest potential therapeutic applications
• Structural analysis reveals a unique tricyclic ring system
