Anti-inflammatory and analgesic activities from roots of Angelica pubescens.

Source

Department of Pharmacology, China Medical College, Taiwan.

In the present study, we extracted Angelica pubescens (AP) with various solvents in order to find the bioactive constituents that demonstrated analgesic and anti-inflammatory effects.

 

The results were obtained as follows:

(1) Methanol-, chloroform-, and ethyl acetate-extracts effectively reduced the pain that was induced by 1% acetic acid and a hot plate.

(2) Methanol-, chloroform-, and ethyl acetate-extracts reduced the edema that was induced by 3% formalin or 1.5% carrageenan.

(3) Sixteen compounds have been isolated and identified from the roots of AP. Among these compounds, columbianadin, columbianetin acetate, bergapten, umbelliferone, and caffeic acid significantly demonstrated anti-inflammatory and analgesic activities at 10 mg/kg.

 

However, only osthole and xanthotoxin revealed anti-inflammatory activity. Isoimperatorin only demonstrated an analgesic effect.

These results revealed that the anti-inflammatory and analgesic constituents from roots of AP were related to peripheral inhibition of inflammatory substances and to the influence on the central nervous system.
