New compounds with hepatoprotective effects from the stems of .

Three new compounds, (8)-2,2,7,7-tetramethyl-8-hydroxymethyl-6-indanone-(2,3-b)-2-pyran-9-O--d-glucopyranoside (), (7,8)-2,2,7-trimethyl-7-hydroxymethyl-8-hydroxy-2,7,8,9-tetrahydro-6-naphtho-(2,3-b)-pyran-10-O--d-glucopyranoside (), 1-deoxy-1-(3,4-dihydro-7-methyl-2,3-dioxo-1(2)-quinoxalinyl)pentitol-6-carboxylic acid (3), as well as six known compounds (), were obtained. Their structures were determined by spectroscopy and comparison with NMR data of related compounds. Absolute configurations were determined by ECD spectroscopy.
