The seeds of Nigella sativa Linn contain a new isobenzofuranone derivative, 5‐hydroxy‐2,2‐dimethyl‐2,8‐dihydro‐6 H ‐furo[3,4‐ g ]chromen‐6‐one (1), obtained from the CHCl 3 extract. Complete 1 H and 13 C assignments of the compound were carried out using one‐dimensional steady‐state difference NOE together with HMQC and HMBC experiments. Copyright © 2001 John Wiley & Sons, Ltd.
