Abstract
|
|
|
|
A flavone glycoside was isolated from the leaves of Betula platyphylla var. latifolia and characterized as by method of chemical and NMR spectral analysis. 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.
