Abstract

Taxifolin 3-O-glucoside isomers, [(2R, 3R)-, (2R, 3S)-, (2S, 3R)- and (2S, 3S)-] were isolated from leaves of Chamaecyparis obtuse (Cupressaceae). Their structures were elucidated on the basis of UV, MS, CD, H-1- and C-13-NMR spectral data, including 2D shift correlation. It was found that the compounds could be distinguished by the use of H-1- and C-13-NMR spectral data.
