Antinociceptive Effect of Triterpenes from Cacti

Abstract

The antinociceptive effects of 20 triterpene sapogenins from cacti were examined by the acetic acid-induced writhing method. The isolation of some triterpenes from the hydrolysate of MeOH extracts of three cacti was also described, and alamosenogenin, bridgesigenins B and C, gummosogenin, thurberogenin and pachanol C, showed the activity.
