New carabrane-type sesquiterpenes, curcarabranols A and B, were isolated from zedoary together with the two known carabrane-type sesquiterpenes curcumenone and 4S-dihydrocurcumenone. The absolute stereostructures of these carabrane-type sesquiterpenes were determined on the basis of physicochemical and chemical evidence. Zedoary sesquiterpenes including 4S-dihydrocurcumenone and curcarabranols A and B were found to inhibit the contraction induced by a high concentration of K⁺ in isolated rat aortic strips.
