Anti-inflammatory studies on Euphorbia prostrata

Area of Science:

• Pharmacology and Ethnobotany
• Natural Product Chemistry

Background:

• Traditional medicine often utilizes plant-based remedies for inflammatory conditions.
• Euphorbia prostrata is a plant with a history of use in folk medicine.

Purpose of the Study:

• To investigate the anti-inflammatory potential of Euphorbia prostrata.
• To evaluate specific fractions of the plant extract for their efficacy in animal models of inflammation.

Main Methods:

• Rats were administered an ethanol extract and partitioned fractions of Euphorbia prostrata.
• Carrageenan-induced paw edema was used to assess acute anti-inflammatory activity.
• Histamine and bradykinin models were employed to determine the mechanism of action.

Main Results:

• The ethyl acetate fraction demonstrated significant inhibition (76%) of carrageenan-induced paw edema at 200 mg/kg.
• A specific isolate (KSE-23) from the ethyl acetate fraction inhibited pedal edema by 57% at 8 mg/kg.
• The extract selectively inhibited histamine-induced edema, indicating suppression of the early inflammatory phase.

Conclusions:

• Euphorbia prostrata possesses notable anti-inflammatory activity, particularly its ethyl acetate fraction.
• The findings suggest that Euphorbia prostrata may target the initial stages of acute inflammation, possibly via histamine pathways.
