Absolute stereostructure of carabrane-type sesquiterpene and vasorelaxant-active sesquiterpenes from Zedoariae Rhizoma

The aqueous acetone extract of Zedoariae Rhizoma was found to show inhibitory effects on contractions induced by high concentrations of potassium cation (K+) in isolated rat aortic strips. From the extract, two new carabrane-type sesquiterpenes

Absolute stereostructures of carabrane-type sesquiterpenes, curcumenone, 4S-dihydrocurcumenone, and curcarabranols A and B: Vasorelaxant activity of Zedoary sesquiterpenes

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.
