The distribution of phenylpropanoid glycosides in Chilean calceolaria Spp.

Abstract The distribution of phenylpropanoid glycosides in Chilean species of Calceolaria belonging to Reiche's section III was investigated by HPLC. Verbascoside, calceolariosides A-E, forsythoside A and isoarenarioside were detected. All species investigated contained verbascoside and/or calceolarioside A. The patterns of these phenolic constituents seem to be characteristic of species and groups of species rather than of higher infrageneric taxa.
