[Chemical constituents of Paederia pertomentosa].
Five constituents were extracted from the aerial part of Paederia pertomentosa and isolated by column chromatography. Their structures were elucidated by physicochemical properties and spectroscopic data analysis. The isolated compounds were identified as 1,2-dimethoxy-3,4-dihydroxyanthraquinone named as paederone (1), paederoside (2), deacetyl asperulosidic acid methyl ester (3), paederosidic acid (4) and methylpaederosidate (5).
