RESUMO
Phytochemical investigation of the aerial parts of S. paludosum afforded 3,4,7,8-tetramethyl gossypetinr, 3,7- dimethyl kaempferol, 3-methyl kaempferol, 3-methyl apigenin, and 3-methyl quercetin ethers, besides N-p-transcoumaroyltiramine, and protocatecuid acid. The structures were established from spectral data of the natural substances and the permethyl and acetyl derivatives of tetramethyl gossypetin.
