From leaves of Engelhardtia crysolepis HANCE (Juglandaceae), which have been used as a sweet tea in China, we have isolated a sweet dihydroflavonol glycoside, and the structure was elucidated on the basis of chemical and spectral evidence as 3-O-β-D-glucopyranosyl(1→3)-α-L-rhamnopyranosyl-(2R, 3R)-taxifolin.
