In vitro and in vivo anti-inflammatory activity of oenothein B from Eucalyptus leaves and its amelioration mechanism on colitis mice by regulating fecal microbiota and metabolism

Key Points

• In vivo results showed a significant anti-inflammatory effect associated with oenothein B administration.
• Treatment led to improved gut health by regulating intestinal microbiota and reducing oxidative stress.
• Assessment of bioactivities highlighted the biological activity of polyphenols extracted from Eucalyptus leaves.
• These findings suggest potential therapeutic applications for oenothein B in managing inflammation.
