乌药提取物的镇痛、抗炎作用研究

Studies on the Analgesic and Antiinflammatory Action of Radix Linderae Extract

乌药的水提液、醇提物水溶液在5、10g/kg两个剂量组下能够明显延长小鼠热板法痛阈值。20g/kg剂量能够显著抑制小鼠因酒石酸锑钾刺激引起的扭体反应,与生理盐水组比较差异有显著性。20g/kg剂量能对抗混合致炎剂所致小鼠耳肿胀,降低肿胀率。乌药中进一步分离所得组分能够有效对抗角叉菜胶大鼠足跖肿胀。

Both of aqueous extract and alconol extract of Radix Linderae at a dose 5g/kg and JO g/kg could length obviously pain threshold in mice in hot plate test. The samples at a dose 20g/kg could inhibit significantly the writhing frequency induced by potassium antimony tartate in mice, also antagonize the swelling of ear induced by inflammatory agent and decrease the swelling rate. The component further isolated from the plant could antagonize the swelling of rat toes induced by carrageenin.
