NMR spectral data of salazinic acid isolated from some species of Parmotrema

In the investigation of lichens from the genus Parmotrema, P. tinctorum and P. delicatulum were examined. Salazinic acid was isolated as the main compound (ca 16%) from both species. Although this depsidone has already been reported for some species of this genus, this is the first report for P. tinctorum. The complete 1H and 13C NMR spectral assignments are reported. These assignments were confirmed by data obtained from HMQC and HMBC spectral analyses. Copyright © 2000 John Wiley & Sons, Ltd.
