Abstract:
Two new cadinane sesquiterpenes (1 and 2) were isolated from Curcuma parviflora, and their structures were elucidated by spectroscopic data. Compound 1, 4α-acetoxycadina-2,9-diene-1,8-dione, possesses two conjugated enone chromophores, while compound 2, 1α,3α,4β-trihydroxy-9-cadinen-8-one, has an enone moiety with three hydroxy groups. Isolation of these cadinane monomers may reasonably suggest that parviflorenes are biogenetically classified as cadinane dimers.
