Abstract

Chemical studies on the constituents of Eranthis cilicica led to isolation of ten chromone derivatives, two of which were previously known. Comprehensive spectroscopic analysis, including extensive 1D and 2D NMR data, and the results of enzymatic hydrolysis allowed the chemical structures of the compounds to be assigned as 8, 11-dihydro-5-hydroxy-2, 9- dihydroxymethyl-4H-pyrano [2, 3-g][1] benzoxepin-4-one, 5, 7-dihydroxy-8-[(2E)-4- ...
