| Abstract: | Three new bisabolocurcumin ethers, named demethoxybisabolocurcumin ether ( 1 ), bisabolocurcumin ether ( 2 ), and didemethoxybisabolocurcumin ether ( 3 ), along with two known compounds, 4 and 5 , were isolated from the AcOEt extract of the rhizomes of Curcuma longa L. Their structures were established by the analysis of NMR and MS data. The new compounds 1 – 3 , which possess a new 1,7‐diarylheptanoid skeleton linked with a bisabolone‐type sesquiterpene substructure by a C? O bond, were found for the first time in a natural source. |
