A new prenylated flavanone glucoside (sophoraflavanone I 7-O-beta-gluc
opyranoside) and three new. resveratrol oligomers, stenophyllols A-C,
were isolated from the roots of Sophora (S.) stenophylla along with si
x known flavonoids and three known resveratrol oligomers. Their struct
ures were determined bg spectroscopic analysis of correlation spectros
copy involving long-range coupling and nuclear Overhouser effect exper
iments.
