A flavone glycoside was isolated from the leaves of Betula platyphylla var. latifolia and characterized as $4, 6-Dimethoxy-5-hydroxyflavone-7-O-{\beta}-D-glucoside(pectolinarigenin-7-O-{\beta}-D-glucopy-ranoside)$ by method of chemical and NMR spectral analysis. $^13C-^1H$ long range coupling was confirmative for determination of its substituted position. In connection with this study, 6-C-Glucosylnalingenin and 6-C-Glucosylaromadendrin were confirmed its structures using this technique.
