Phenolic Metabolites from the Stems and Leaves of Sophora flavescens

Two new compounds, (-)-(6aR,11aR)-4-methoxy-8,9-(methylenedioxy)pterocarpan 3-O-beta-D-glucopyranosid (1) and 5-hydroxy-7-methoxyisoflavone 4'-O-beta-D-xylopyranosyl-(1 -> 6)-beta-D-glucopyranoside (2), were isolated, together with 30 known compounds from the stems and leaves of Sophora flavescens AITION. Their structures were elucidated by extensive spectroscopic analysis, including HR-ESI-MS data. A preliminary comparison of phenolic metabolite profiles, based on the qualitative HPLC analysis, indicated that the composition of the roots and the aerial parts were significantly different.
