摘要

杉木素3- o -糖苷异构体[(2R, 3R)-, (2R, 3S)-, (2S, 3R)-和(2S, 3S)-]分别从柏科Chamaecyparis obtuse(柏科)叶片中分离得到。利用UV、MS、CD、1H-和13C-NMR光谱数据,包括二维位移相关,对它们的结构进行了分析。利用1H- nmr和13C-NMR谱数据可以区分化合物。

Separation and identification of Taxifolin 3-O-glucoside isomers from Chamaecyparis obtusa (Cupressaceae).

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, 1H- and 13C-NMR spectral data, including 2D shift correlation. It was found that the compounds could be distinguished by the use of 1H- and 13C-NMR spectral data.
