Abstract

5,7,3′-trihydroxy-2′,4′,5′-trimethoxyflavone Compositae diterpene kaurane LR-HETCOR NMR NOESY Psiadia arabica psiadin X-ray
The aerial parts of Psiadia arabica yielded two new constituents: a flavone, 5,7,3′-trihydroxy-2′,4′,5′-trimethoxyflavone, the structure of which was derived from spectral data and chemical derivatization, and a kaurane diterpene named psiadian, which was characterized unambiguously from its chemical and spectral data in conjunction with X-ray crystallography.
