The syntheses of multiply 13 C-labelled derivatives of the two mammalian lignans, enterolactone and enterodiol, and two of their plant lignan precursors, secoisolariciresinol and matairesinol, are described. Three 13 C atoms were incorporated into each lignan using potassium [ 13 C]cyanide as the so
## Abstract The use of the nominal value of the chemical shift of the solvent to calibrate the spectrometer in ^13^C NMR spectroscopy was found to introduce errors due to the effect which the solute has on the solvent. In addition, hexamethyldisiloxane (HM) is proposed as an internal standard; owin
