抄録

Petroleum ether extract of the heartwood of Tecomella undulata affords radermachol, an unusual rare pigment and 2-isopropenylnaphtho[2,3-b]furan-4,9- quinone along with lapachol, tecomaquinone-I, dehydro-α-lapachone, α-lapachone, β-lapachone, cluytyl ferulate, stigmasterol and β-sitosterol. Radermachol and 2-isopropenylnaphtho [2,3-b]furan-4,9-quinone are being reported for the first time from genus Tecomella. Complete assignments of 1H and 13C NMR signals of polyketide, radermachol 1, have been achieved by the 13C NMR chemical shift prediction using ab initio MO and DFT/GIAO methods in addition to 2D-NMR techniques.
