Abstract
- In this study, we prepared alcohol extracts of the larva, pupa, queen, and cocoon (clony) of B. ignitus, B. terrestris, and B. h. sapporoensis, and tested the anti-inflammatory activity of the extracts by using a rat model of adjuvant-induced edema. The extracts derived from the queen of B. ignitus, the queen of B. terrestris, and the cocoon of B. ignitus decreased hind paw edema after 1 day of i.p. administration. These extracts also induced vasorelaxation and NO production in calf pulmonary artery endothelial cells. These results suggest that bumblebee alcohol extracts has anti-inflammatory and vasorelaxant properties.
