Resumen

SILVA, Tania Maria Sarmento da et al. Constituintes químicos do extrato acetato de etila das partes aéreas de Solanum paludosum Moric. Rev. bras. farmacogn. [online]. 2002, vol.12, suppl.1, pp. 85-86. ISSN 0102-695X.  http://dx.doi.org/10.1590/S0102-695X2002000300042.

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.
