Chemical constituents from root of Glycyrrhiza uralensis / 中草药

Object To investigate the chemical constituents from the roots of Glycyrrhiza uralensis Fisch. Methods The constituents were isolated on normal and reversed silica gel column chromatography and their structures were identified by spectral evidence. Results A new oleanane-type triterpenoid saponin and twelve known compounds, including two triterpenoid saponins, two cumarins and eight flavonoids, were isolated. Conclusion The new compound was elucidated as 3-O-[β-D-(6-methyl) glucuronopyranosyl (1→2)-D-glucuronopyranosyl]-24-hydroxy-glabrolide on the basis of ESI-MS, 1HNMR,13CNMR, HMQC and HMBC spectral evidence.
