In addition to the known mutisicoumarin A, the aerial parts of the shrub Mutisia friesiana afforded five new methylphenones, two new 5-methylcoumarins and a new related chromone. Their structures were elucidated by spectroscopic methods 13C NMR data for mutisicoumarin A are reported for the first
In addition to the known mutisicoumaranones A (1) and B (2), the methanolic extract of the aerial parts of the shrub Mutisia friesiana afforded two new 5-methylcoumaranones, mutisicoumaranones C (3) and D (4). Their structures were elucidated by spectroscopic methods. (13)C NMR data for
