Quercetagetin 7-methyl ether glycosides from Paepalanthus vellozioides and Paepalanthus latipes
Phytochemistry, 1999 Several new quercetagetin 7-methyl ether glycosides were characterized from the ethanolic extracts of scapes and leaves of Paepalanthus vellozioides and P. latipes. Their structures were determined mainly by 600 MHz NMR spectroscopy.

Naphthopyranone glycosides from Paepalanthus bromelioides
Phytochemistry, 1998Abstract Two new naphtho[2,3C]pyran-1-one glycosides, paepalantine-9-O-β- d -glucopyranoside and paepalantine-9-O-β- d -allopyranosyl(1 → 6)glucopyranoside, were isolated from an ethanolic extract of capitula from Paepalanthus bromelioides and identified from their spectrometric data.
