Abstract
Chemical investigation of the lichen Parmotrema dilatatum led to
the isolation of a new chlorinated compound, named dilatatone
(1), along with a known compound, sernanderin (2). Their chemical
structures were determined by analysis of their 1D and 2D
NMR spectra, HRESIMS, and ECD data. Both compounds showed
weak a-glucosidase inhibitor activity.
