Screening of Effective Parts of Anti-inflammatory from Ageratum Conyzoide L.
Objective:With different polar extraction of Ageratum Conyzoide L.,Screening of effective parts of anti-inflammatory from Ageratum Conyzoide L.. Methods:the different polar extractions of Ageratum Conyzoide L.were extracted by the petroleum ether,the ethyl acetate,n-butanol and the water in sequence.The effect of different polar extraction of Ageratum Conyzoide L on inflammation was studied by the ear swelling experiment of mice induced by xylene and the capillary permeability in abdominal cavity of mice induced by acetic acid. Results: The degree of ear swelling experiment of mice was significantly inhibited by the extract parts of petroleum ether, the ethyl acetate, n-butanol (P<0.01 or P<0.05), and the capillary permeability in abdominal cavity of mice induced by acetic acid was decreased significantly by the extract parts of water P<0.05).Conclusion:all polar extractions of Ageratum Conyzoide L.had anti-inflammatory effect.
