Abstract:
OBJECTIVETo study the chemical constituents of the whole plant of Viola yedoensis.
METHODThe compounds were isolated by various chromatographic techniques and their structures were elucidated by their physicochemical properties and the analysis of their spectral data.
RESULTSeven compounds were isolated and identified as esculetin (1), isoscopoletin (2), 6-hydroxymethyl-3-pyridinol (3),5,5-bi (6,7-dihydroxycoumarin) (4), 6,6,7,7-tetrahydroxy-5,8-bicoumarin (5), loliolide (6), dehydrololiolide (7).
