Abstract:
Notopterol was identified as the analgesic component of Notopterygium incisum TING by using the acetic acid-induced writhing method. Notopterol also indicated an anti-inflammatory activity by its inhibitory effect in the vascular permeability test. The intensive prolongation of pentobarbital-induced hypnosis was possibly caused by its inhibitory effect on the drug metabolism in liver. Pharmacological differences between the analgesic components of N. incisum, Aralia cordata and Angelica pubescens were also discussed.
