Abstract:
Objective:To study the anti-inflammatory and analgesic effects of the volatile oil from Piper puberulum ( Benth. ) Max-im. in Guizhou. Methods:Fifty KM mice were randomly divided into five groups (10 ones in each), the model control group (sa-line), low concentration volatile oil group (0. 125 ml/100 ml), medium concentration volatile oil group (0. 25 ml/100ml), high con-centration volatile oil group (0. 5 ml/100 ml) and aspirin group (3 mg·ml-1). Mouse ear swelling induced by xylene and skin capil-lary permeability were used to evaluate anti-inflammatory activity of the volatile oil from Piper puberulum ( Benth. ) Maxim. in Guizhou. Acetic acid-induced abdominal eonstrietion test and hot-plate test were applied to evaluate anti-analgesic activity of the vola-tile oil from Piper puberulum ( Benth. ) Maxim. In Guizhou. Results:Compared with that in the model group, the mouse ear swelling in the medium concentration volatile oil group, high concentration volatile oil group and aspirin group was significantly reduced ( P<0. 05). The skin capillary permeability in the high concentration volatile oil group and aspirin group was significantly reduced (P<0. 05 or P<0. 01). Compared with that in the model group, the writhing times in the medium concentration volatile oil group, high concentration volatile oil group and aspirin group were significantly reduced (P<0. 05 or P<0. 01). The pain threshold in the high concentration volatile oil group was effectively reduced (P<0. 05 or P<0. 01). Conclusion: The volatile oil from Piper puberulum ( Benth. ) Maxim. in Guizhou has promising anti-inflammatory and analgesic activities.
