Abstract:
:A new dehydrodigallic acid derivative (1), along with 19 known compounds, including 6 phenolic derivatives, 2 steroids and 11 triterpenoids were isolated from the ethanol extract of the root of Geum urbanum. Herein, there is the first report of steroid and triterpene in Geum urbanum. The purified metabolites were characterised by NMR spectroscopic and mass spectrometric analyses. The identification of the known compounds (2-20) was based on the comparison of their NMR spectroscopic features with previously published data. The structural characteristics of compound 1 were elucidated by comprehensive 1D and 2D NMR spectroscopic methods and acid hydrolysis.
