To study the anti-inflammatory and analgesic activities of different fractions extracted from Clematis manshurica Rupr.Methods:The parts of petroleum ether,chloroform,ethyl acetate and n-butanol were obtained by abstracting,extracting and concentrating.The experiment was divided into three groups:negative control group,positive control group and experimental group.In the study,mouse acetic acid writhing and lipopolysaccharide (LPS) induced RAW264.7 cell model were used to evaluate analgesic and anti-inflammatory activity of the four fractions.Results:In the experiment of analgesic,the inhibition rate of writhing was the most significant in the ethyl acetate fraction.The results of anti-inflammatory experiment suggested that the ethyl acetate fraction showed significant inhibitory effect on nitric oxide (NO).Conclusion:The anti-inflammatory and analgesic effects of different parts of Clematis mandshurica were different,and ethyl acetate fraction showed the most significant anti-inflammatory and analgesic activity.
